| Description |
Mount Oyama is a 820-meter-high (2,700 feet) volcano on the island of Miyake-Jima, Japan. In late June 2000, a series of earthquakes alerted scientists to possible volcanic activity. On June 27, authorities evacuated 2,600 people, and on July 8 the volcano began erupting and erupted five times over that week. The dark gray blanket covering green vegetation in the image is the ash deposited by prevailing northeasterly winds between July 8 and 17. This island is about 180 kilometers (110 miles) south of Tokyo and is part of the Izu chain of volcanic islands that runs south from the main Japanese island of Honshu. Miyake-Jima is home to 3,800 people. The previous major eruptions of Mount Oyama occurred in 1983 and 1962, when lava flows destroyed hundreds of houses. An earlier eruption in 1940 killed 11 people. This image is a perspective view created by combining image data from the Advanced Spaceborne Thermal Emission and Reflection Radiaometer (ASTER) aboard NASA's Terra satellite with an elevation model from the Shuttle Radar Topography Mission (SRTM). Vertical relief is exaggerated, and the image includes cosmetic adjustments to clouds and image color to enhance clarity of terrain features. The ASTER instrument is a cooperative project between NASA, JPL, and the Japanese Ministry of International Trade and Industry. ASTER is operating on-board NASA's Terra platform. Elevation data used in this image was acquired by the Shuttle Radar Topography Mission (SRTM) aboard the Space Shuttle Endeavour, launched on February 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X- Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. SRTM was designed to collect three-dimensional measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter-long (200-foot) mast, installed additional C-band and X-band antennas, and improved tracking and navigation devices. The mission is a cooperative project between the National Aeronautics and Space Administration (NASA), the National Imagery and Mapping Agency (NIMA) of the U.S. Department of Defense (DoD), and the German and Italian space agencies. It is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Earth Science Enterprise, Washington, DC.

| Description |
Southern California's dramatic topography plays a critical role in the region's climate, hydrology, ecology, agriculture and habitability. This image of Southern California from NASA's Shuttle Radar Topography Mission (SRTM) shows a variety of landscapes and environments from the desert at Mojave to the ocean at Ventura. Winds usually bring moisture to this area from the west, moving from the ocean, across the coastal plains to the mountains, and then to the deserts. Most rainfall occurs as the air masses rise over the mountains and cool with altitude. Continuing east, and now drained of their moisture, the air masses drop in altitude and warm as they spread across the desert. The mountain rainfall supports forest and chaparral vegetation, seen here, and also becomes ground water and stream flow that supports citrus, avocado, strawberry, other crops, and a large and growing population on the coastal plains. This perspective view was generated by draping a Landsat satellite image over a preliminary topographic map from SRTM. It shows the Tehachapi Mountains in the right foreground, the city of Ventura on the coast at the distant left and the easternmost Santa Ynez Mountains forming the skyline at the distant right. Landsat has been providing visible and infrared views of Earth since 1972. SRTM elevation data matches the 30-meter (33-yard) resolution of most Landsat images and will substantially help in analyses of the large and growing Landsat image archive. The elevation data used in this image was acquired by SRTM aboard the Space Shuttle Endeavour, launched on February 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. SRTM was designed to collect three-dimensional measurements of Earth's surface.

| Description |
Los Angeles may be the world's entertainment capital, but it is a difficult place to locate television and radio antennas. The metropolitan area spreads from the Pacific Ocean to Southern California's upper and lower deserts, valleys, mountains, canyons and coastal plains. While this unique geography offers something for everyone in terms of urban, suburban, small-town, and even semi-rural living, reception of television and radio signals can be problematic where there is no line-of-sight to a transmitting antenna. Broadcasters must choose antenna sites carefully in order to reach the greatest number of customers. Most local television towers are located atop Mount Wilson (elevation 1740 m =5710 ft), which is located on the front range of the San Gabriel Mountains (indistinctly visible, just right of the image center). This site is preferable to the highest peak seen here (Mount Baden-Powell, 2865 m =9399 ft) because it's closer to the urban center and has fewer obstructing peaks. It is also situated at a protruding bend in the mountain front and has few obstructions to the left and right. Computer automated methods combined with elevation models produced by SRTM will quantitatively optimize such factors in the siting of future transmission antenna installations worldwide. This perspective view looks northeastward from the Santa Monica Bay. The San Fernando Valley is on the left, Pasadena is against the mountain front at right-center, and downtown Los Angeles is on the coastal plain directly in front of Mount Baden-Powell. This image was generated by draping a Landsat satellite image over a preliminary topographic map from the Shuttle Radar Topography Mission (SRTM). Landsat has been providing visible and infrared views of the Earth since 1972. SRTM elevation data matches the 30-meter resolution of most Landsat images and will substantially help in analyses of the large and growing Landsat image archive.

| Description |
The 1,200-kilometer (800-mile) San Andreas is the longest fault in California and one of the longest in North America. This perspective view of a portion of the fault was generated using data from the Shuttle Radar Topography Mission (SRTM), which flew on NASA's Space Shuttle last February, and an enhanced, true- color Landsat satellite image. The view shown looks southeast along the San Andreas where it cuts along the base of the mountains in the Temblor Range near Bakersfield. The fault is the distinctively linear feature to the right of the mountains. To the left of the range is a portion of the agriculturally rich San Joaquin Valley. In the background is the snow-capped peak of Mt. Pinos at an elevation of 2,692 meters (8,831 feet). The complex topography in the area is some of the most spectacular along the course of the fault. To the right of the fault is the famous Carrizo Plain. Dry conditions on the plain have helped preserve the surface trace of the fault, which is scrutinized by both amateur and professional geologists. In 1857, one of the largest earthquakes ever recorded in the United States occurred just north of the Carrizo Plain. With an estimated magnitude of 8.0, the quake severely shook buildings in Los Angeles, caused significant surface rupture along a 350-kilometer (220-mile) segment of the fault, and was felt as far away as Las Vegas, Nev. This portion of the San Andreas is an important area of study for seismologists. For visualization purposes, topographic heights displayed in this image are exaggerated two times. The elevation data used in this image was acquired by SRTM aboard the Space Shuttle Endeavour, launched on February 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on Endeavour in 1994. SRTM was designed to collect three-dimensional measurements of Earth's land surface. To collect the 3-D SRTM data, engineers added a mast 60 meters (about 200 feet) long, installed additional C-band and X-band antennas, and improved tracking and navigation devices. The mission is a cooperative project between the NASA, the National Imagery and Mapping Agency (NIMA) of the U.S. Department of Defense, and the German and Italian space agencies. It is managed by NASA's Jet Propulsion Laboratory, Pasadena, Calif, for NASA's Earth Science Enterprise, Washington, D.C. JPL is a division of the California Institute of Technology in Pasadena.

| Description |
Japan's Mt. Fuji presents a beautiful backdrop for the city of Tokyo in this perspective view generated using data from the Shuttle Radar Topography Mission. Occupying most of the image foreground, Tokyo's metropolitan area, at about 13,388 square kilometers (5,169 square miles), is home to more than 32 million people, making it the most densely populated urban area in the world. Tokyo residents live within striking distance of Japan's tallest volcano, which is also the country's highest point at 3,776 meters (12,388 feet). Mt. Fuji is still considered active, although the last major eruption of this perfectly symmetrical stratovolcano came in 1707. Because of its height and spectacular scenery, Mt. Fuji is a favorite for touring, mountain climbing and hiking. In this image, elevations are represented by color, height increases from white to green to brown. For visualization purposes, topographic heights are exaggerated two times. Other SRTM views of Mt. Fuji and Tokyo can be seen in PIA-02791 and PIA-02792. The elevation data used in this image was acquired by SRTM aboard the Space Shuttle Endeavour, launched on February 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on Endeavour in 1994.

| description |
The Earth's surface is broken. Cracks in the Earth's crust known as faults can run for hundreds of kilometers. These faults are frequently the sites of major earthquakes as the tectonic plates that cover the surface of the Earth shift. Pictured above is San Andreas Fault in California, one of the longest and most active faults. Visible as the linear feature to the right of the mountains, San Andreas Fault reaches 15 kilometers deep and is about 20 million years old. The above exaggerated-height image was created by combining radar deployed by the Space Shuttle Endeavour in February 2000 with a true-color Landsat picture. Along San Andreas Fault, the titanic Pacific Plate is shifting relative to the huge North American Plate by an average of a few centimeters per year. At that rate, in a few million years, the Earth's surface will look quite different than it does today. |

3-D Perspective Kamchatka Peninsula Russia |
| Full Description |
This perspective view shows the western side of the volcanically active Kamchatka Peninsula in eastern Russia. The image was generated using the first data collected during the Shuttle Radar Topography Mission (SRTM). In the foreground is the Sea of Okhotsk. Inland from the coast, vegetated floodplains and low relief hills rise toward snow capped peaks. The topographic effects on snow and vegetation distribution are very clear in this near-horizontal view. Forming the skyline is the Sredinnyy Khrebet, the volcanic mountain range that makes up the spine of the peninsula. High resolution SRTM topographic data will be used by geologists to study how volcanoes form and to understand the hazards posed by future eruptions. This image was generated using topographic data from SRTM and an enhanced true-color image from the Landsat 7 satellite. This image contains about 2,400 meters (7,880 feet) of total relief. The topographic expression was enhanced by adding artificial shading as calculated from the SRTM elevation model. The Landsat data was provided by the United States Geological Survey's Earth Resources Observations Systems (EROS) Data Center, Sioux Falls, South Dakota. SRTM, launched on February 11, 2000, used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. To collect the 3-D SRTM data, engineers added a 60- meter-long (200-foot) mast, installed additional C-band and X-band antennas, and improved tracking and navigation devices. SRTM collected three dimensional measurements of nearly 80 percent of the Earth's surface. SRTM is a cooperative project between NASA, the National Imagery and Mapping Agency (NIMA) of the U.S. Department of Defense, and the German and Italian space agencies. Size: 33.3 km (20.6 miles) wide x 136 km (84 miles) coast to skyline. Location: 58.3 deg. North lat., 160 deg. East long. Orientation: Easterly view, 2 degrees down from horizontal.

3-D Perspective Pasadena, California |
| Full Description |
This perspective view shows the western part of the city of Pasadena, California, looking north towards the San Gabriel Mountains. Portions of the cities of Altadena and La Canada, Flintridge are also shown. The image was created from three datasets: the Shuttle Radar Topography Mission (SRTM) supplied the elevation data, Landsat data from November 11, 1986 provided the land surface color (not the sky) and U.S. Geological Survey digital aerial photography provides the image detail. The Rose Bowl, surrounded by a golf course, is the circular feature at the bottom center of the image. The Jet Propulsion Laboratory is the cluster of large buildings north of the Rose Bowl at the base of the mountains. A large landfill, Scholl Canyon, is the smooth area in the lower left corner of the scene. This image shows the power of combining data from different sources to create planning tools to study problems that affect large urban areas. In addition to the well-known earthquake hazards, Southern California is affected by a natural cycle of fire and mudflows. Wildfires strip the mountains of vegetation, increasing the hazards from flooding and mudflows for several years afterwards. Data such as shown on this image can be used to predict both how wildfires will spread over the terrain and also how mudflows will be channeled down the canyons. The Shuttle Radar Topography Mission (SRTM), launched on February 11, 2000, uses the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. The mission was designed to collect three dimensional measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter-long (200-foot) mast, an additional C-band imaging antenna and improved tracking and navigation devices.

3D View of Mount Miyake-Jima, Japan |
| Description |
This 3D perspective view shows the Japanese island called Miyake-Jima viewed from the northeast. This island?about 180 kilometers (110 miles) south of Tokyo?is part of the Izu chain of volcanic islands that runs south from the main Japanese island of Honshu. Dominated by the 820-meter-high (2,700 feet) volcano Mount Oyama, Miyake-Jima is home to 3,800 people. In late June 2000, a series of earthquakes alerted scientists to possible volcanic activity and on June 27 authorities evacuated 2,600 people. On July 7, the island was hit by a typhoon passing overhead, and on July 8 the volcano began erupting. The volcano erupted five times over the next week, spreading gray ash over surrounding areas. Detailed topographic information can be used to predict the directions that lava flows will take. The previous major eruption of Mount Oyama occurred in 1983, when lava flows destroyed hundreds of houses, and an earlier eruption in 1940 killed 11 people. This three-dimensional perspective view was generated using topographic data from the Shuttle Radar Topography Mission. A computer-generated artificial light source illuminates the elevation data to produce a pattern of light and shadows, while colors show the elevation as measured by SRTM. Slopes facing the light appear bright, while those facing away are shaded. On flatter surfaces, the pattern of light and shadows can reveal subtle features in the terrain. The elevation is indicated by colors. Lowest elevation areas appear blue, medium elevations appear green, while higher elevations appear brown and white. The Shuttle Radar Topography Mission (SRTM), launched on February 11, 2000, used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. SRTM was designed to collect three-dimensional measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter-long (200-foot) mast, installed additional C-band and X-band antennas, and improved tracking and navigation devices. The mission is a cooperative project between the National Aeronautics and Space Administration (NASA), the National Imagery and Mapping Agency (NIMA) of the U.S. Department of Defense (DoD), and the German and Italian space agencies.

| Description |
This dramatic view looks west along the Cucharas River Canyon in Colorado toward the 4,152 meter (13,623 ft) high Spanish Peaks, in the foothills of the Sangre De Cristo Mountains. The Peaks are the remnants of a 20-million-year-old volcano. Rising 2,100 meters (7,000 ft) above the plains to the east, these igneous rock formations with intrusions of eroded sedimentary rock historically served as guiding landmarks for travelers on the Mountain Branch of the Santa Fe Trail. This three-dimensional perspective view was generated using topographic data from the Shuttle Radar Topography Mission [ http://www.jpl.nasa.gov/srtm/ ] (SRTM) and an enhanced false-color Landsat 5 satellite image. Colors are from Landsat bands 5, 4, and 2 as red, green, and blue, respectively. The height of the terrain is exaggerated by two times. Landsat has been providing visible and infrared views of the Earth since 1972. SRTM elevation data matches the 30-meter resolution of most Landsat images and will substantially help in analyses of the large and growing Landsat image archive.

Earthquake in Northern Chile

Earthquake in Northern Chile |
| Description |
A 7.8 earthquake rattled northern Chile on June 13, 2005, at 6:44 p.m. local time, killing 11 and leaving hundreds homeless, according to the Associated Press. The large quake shook much of South America and was felt in Brasilia, Brazil, approximately 2,400 kilometers to the east and in Santiago, Chile, 1,515 kilometers to the south. The most damage occurred near the earthquake?s center in the rural, mountainous section of the Tarapaca Province, where the shaking triggered landslides and flattened houses. This topographical image of northern Chile shows the geology that produced this earthquake. The center of the earthquake is represented with a plus sign in the image. To the east, pink represents the higher elevation of the mountains, with the highest peaks tipped in white. Among the tallest is the 5,995-meter-high Cerro Sillajhuay on the border with Bolivia. The steeply changing elevation and folds in the land around the earthquake?s center make it easy to see why the earthquake caused landslides. To the west of the center, the land gradually flattens into the flat Pampa del Tamarugal, a broad green ribbon of low-elevation land. Far to the west of the region shown here, the Nazca Plate (a section of the Earth?s crust that carries part of the Pacific Ocean) pushes steadily under the South American Plate, pushing up the Andes Mountains along the western edge of South America. Earthquakes happen frequently where sections of the Earth?s crust collide, and Chile is particularly prone to geologic activity. The same conditions that give rise to earthquakes have also produced some 620 volcanoes throughout the country. The June 13 earthquake occurred east of the plate?s surface boundary, near the base of the Cordillera Occidental, a range of the Andes. The quake was centered deep in the Earth, 119 kilometers (74 miles) from the surface, where the land is being forced up by the now subducted Nazca Plate. This topographical image was created using data from the Shuttle Radar Topography Mission (SRTM) [ http://www2.jpl.nasa.gov/srtm/ ]. SRTM was designed to collect three-dimensional measurements of the Earth?s surface using a radar instrument that flew aboard the Space Shuttle Endeavour in February 2000.

Earthquake in Sulawesi
| Title |
Earthquake in Sulawesi |
| Description |
In the quiet of the earliest hours of the morning on January 24, 2005, a magnitude 6.2 earthquake rattled Palu, Sulawesi, killing one and injuring four others. The earthquake was centered approximately 35 kilometers (20 miles) south of Palu, 10 kilometers (6.2 miles) beneath the surface. Located in the center of the arc of islands that forms Indonesia, Sulawesi is at the heart of one of the most geologically active regions in the world. The effect of millennia of shifting ground on the island is readily apparent in this elevation image, created using data from the Shuttle Radar Topography Mission (SRTM). SRTM was designed to collect three-dimensional measurements of the Earth's surface using a radar instrument that flew aboard the Space Shuttle Endeavour in February 2000. In the above image, the highest elevations are white and pink, while low elevations are green. Two mountain ranges run north-south from the center of the island to the shore. Between the two ranges, a finger of green marks out a straight valley that was formed by the fault. As this image reveals, the January 24 earthquake was centered just a few kilometers west of this fault. Like the San Andreas fault, Sulawesi's fault is a transform fault formed when two tectonic plates slide past one another. Indonesia sits on top of three major tectonic plates—giant slabs of the Earth's crust that float on the planet's molten core. The majority of the islands in the nation sit on the Eurasian plate, caught between the north-moving Australian plate, and the west-moving Pacific plate. Around Sulawesi, three smaller plates clash, adding to the seismic activity. All of this jostling between plates leads to frequent earthquakes and active volcanoes, Indonesia has more historically active volcanoes (76) than any other region on Earth.

Earthquakes near Niigata, Japan |
| Description |
A series of powerful earthquakes over the weekend shook Niiagata Prefecture on Northwest Honshu, 260 km (160 miles) north of Tokyo. The first quake registered 6.5 on the Richter Scale, according to the National Earthquake Information Center, and occurred at 8:56 Universal Time on October 23, 2004, in the early evening local time as many residents were starting their dinners. As of October 25, some 24 deaths have been attributed to the quake, or to the series of strong aftershocks, some above 6.0 in magnitude. Rescuers are still looking for missing people and, unfortunately, the death toll may climb further. The quakes also injured approximately 2,000 people, stretching local hospitals to their limits. Electrical power has been cut off for some 300,000 residents. Many people remain in emergency shelters, fearful of returning to homes that may be unstable from the damage caused by the quakes. Earthquakes are not uncommon in Japan, which rests on the Pacific ?Rim of Fire,? where the North American plate (on which northern Honshu rests) grates up against the Eurasian Plate. This visualization shows the topography of northwestern Japan around the initial epicenter. Color represents elevation and shading shows slope (illuminated from the lower left, as the area would appear at this time of year in the early morning). The land surface elevation data shown here were collected by NASA?s Shutte Radar Topograph Mission (SRTM) in February 2000. The locations and information about the quakes were obtained from the USGS National Earthquake Information Center.

Eruption of Sicily's Mt. Etna |
| Description |
Italy?s Mount Etna is the focus of this 3-D perspective view made from data collected by the Advanced Spaceborne Thermal and Emission Radiometer (ASTER), flying aboard NASA?s Terra spacecraft, and overlaid on Shuttle Radar Topography Mission (SRTM) topography. The image is looking south with dark lava flows from the 1600s (center) to 1981 (long flow at lower right) visible in the foreground and the summit of Etna above. The city of Catania is barely visible behind Etna on the bay at the upper left. In late October 2002, Etna erupted again, sending lava flows down the south and east sides of the volcano, out of sight in this view. In addition to the terrestrial applications of these data for understanding active volcanoes and hazards associated with them such as lava flows and explosive eruptions, geologists studying Mars find these data useful as an analog to martian landforms and geologic processes. In late September 2002, a field conference with the theme of Terrestrial Analogs to Mars focused on Mount Etna, allowing Mars geologists to see in person the types of features they can only sample remotely. Elevation data used in this image was acquired by SRTM aboard the Space Shuttle Endeavour, launched on Feb. 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. SRTM was designed to collect 3-D measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter (approximately 200-foot) mast, installed additional C-band and X-band antennas, and improved tracking and navigation devices. The mission is a cooperative project between NASA, the National Imagery and Mapping Agency (NIMA) of the U.S. Department of Defense and the German and Italian space agencies.

Mt. Ruapehu, New Zealand
| Title |
Mt. Ruapehu, New Zealand |
| Description |
All around the world, people live in places where the threat of natural disaster is high. On the North Island of New Zealand, the Mount Ruapehu volcano is just such a threat. A towering, active stratovolcano (the classic cone-shaped volcano), snow-capped Ruapehu Volcano is pictured in this enhanced-color image. The image is made from topography data collected by the Shuttle Radar Topography Mission aboard the Space Shuttle Endeavour, launched on February 11, 2000, and imagery collected by the Landsat satellite on October 23, 2002. Ruapehu is one of New Zealand?s most active volcanoes, with ten eruptions since 1861. The eruptions aren?t the only threat from the volcano, however. Among the most serious threats is a volcanic mudflow called a lahar. In between eruptions, a lake forms in the volcano?s caldera from melting snow. If a previous eruption has deposited a dam of ash, rocks and mud in the lake?s natural overflow point, then the lake becomes dangerously full, held back only by the temporary dam. In this scene, the lake is nestled among the ridges at the top of the volcano. Eventually, the dam gives way and a massive flow of mud and debris churns down the mountain toward farmland and towns below. Scientists estimate that Ruapehu has experienced 60 lahars in the last 150 years. A devastating lahar in 1953 killed more than 150 people, who died when a passenger train plunged into a ravine when a railroad bridge was taken out by the lahar. The flank of the volcano below the lake is deeply carved by the path of previous lahars, the gouge can be seen just left of image center. Currently scientists in the region are predicting that the lake will overflow in a lahar sometime in the next year. There is great controversy about how to deal with the threat. News reports from the region indicate that the government is planning to invest in a high-tech warning system that will alert those who might be affected well in advance of any catastrophic release. Others feel that the government should combat the threat through engineering at the top of the mountain, for example, by undertaking a controlled release of the lake.

Relief Map, Yucatan Peninsul
…
| Title |
Relief Map, Yucatan Peninsula, Mexico |
| Description |
This shaded relief image of Mexico's Yucatan Peninsula show a subtle, but unmistakable, indication of the Chicxulub impact crater. Most scientists now agree that this impact was the cause of the Cretatious-Tertiary Extinction, the event 65 million years ago that marked the sudden extinction of the dinosaurs as well as the majority of life then on Earth. Most of the peninsula is visible here, along with the island of Cozumel off the east coast. The Yucatan is a plateau composed mostly of limestone and is an area of very low relief with elevations varying by less than a few hundred meters (about 500 feet.) In this computer-enhanced image the topography has been greatly exaggerated to highlight a semicircular trough, the darker green arcing line at the upper left corner of the peninsula. This trough is only about 3 to 5 meters (10 to 15 feet) deep and is about 5 km. wide (3 miles), so subtle that if you walked across it you probably would not notice it, and is a surface expression of the crater's outer boundary. Scientists believe the impact, which was centered just off the coast in the Caribbean, altered the subsurface rocks such that the overlying limestone sediments, which formed later and erode very easily, would preferentially erode on the vicinity of the crater rim. This formed the trough as well as numerous sinkholes (called cenotes) which are visible as small circular depressions. Two visualization methods were combined to produce the image: shading and color coding of topographic height. The shade image was derived by computing topographic slope in the northwest-southeast direction, so that northwestern slopes appear bright and southeastern slopes appear dark. Color coding is directly related to topographic height, with green at the lower elevations, rising through yellow and tan, to white at the highest elevations.

SRTM Anaglyph: Haro and Kas
…
| Title |
SRTM Anaglyph: Haro and Kas Hills |
| Description |
On January 26, 2001 the Kachchh region in western India suffered the most deadly earthquake in India's history. This three-dimensional view of landforms northeast of the city of Bhuj depicts geologic structures that are of interest in the study the tectonic processes that may have led to that earthquake. However, preliminary field studies indicate that these structures are composed of Mesozoic rocks that are overlain by younger rocks showing little deformation. Thus these structures may be old, not actively growing, and not directly related to the recent earthquake. The Haro Hills are on the left and the Kas Hills are on the right. The Haro Hills are an "anticline," which is an upwardly convex elongated fold of layered rocks. The anticline is distinctly ringed by an erosion resistant layer of sandstone. The east-west orientation of the anticline may relate to the crustal compression that has occurred during India's northward movement toward, and collision with, Asia. In contrast, the largest of the Kas Hills appears to be a tilted (to the south) and faulted (on the north) block of layered rocks. Also seen here, the curvilinear ridge trending toward the southwest from the image center is an erosion resistant "dike," which is an igneous intrusion into older "host" rocks along a fault plane or other crack. The dike also appears to extend northeast from the image center as a dark line having very little topography. Its location between the tilted block and a smaller anticline to the north (directly east of the larger anticline) probably indicates that the dike fills the fault that separates these contrasting geologic structures. These features are simple examples of how digital elevation data can stereoscopically enhance satellite imagery to provide a direct input to geologic studies. The stereoscopic effect of this anaglyph was created by first draping a Landsat satellite image (taken just two weeks after the earthquake) over preliminary digital elevation data from the Shuttle Radar Topography Mission (SRTM), and then generating two differing perspectives, one for each eye. When viewed through special glasses, the result is a vertically exaggerated view of the Earth's surface in its full three dimensions. Anaglyph glasses cover the left eye with a red filter and cover the right eye with a blue filter. Landsat has been providing visible and infrared views of the Earth since 1972. SRTM elevation data matches the 30-meter resolution of most Landsat images and will substantially help in analyses of the large and growing Landsat image archive. The Landsat 7 Thematic Mapper image used here was provided to the SRTM project by the United States Geological Survey, Earth Resources Observation Systems (EROS) Data Center, Sioux Falls, South Dakota. Elevation data used in this image was acquired by the Shuttle Radar Topography Mission (SRTM) aboard the Space Shuttle Endeavour, launched on February 11,2000.

Orientation: North toward the top Image Data: Landsat Panchromatic Band (visible and near infrared) Date Acquired: February 2000 (SRTM), February 9, 2001 (Landsat), These two images are two-dimensional (top) and three-dimensional (bottom)views of the same area, southeast of Bhuj, India. Together they demonstrate how NASA's Shuttle Radar Topography Mission(SRTM) elevation models can be used to help in the interpretation of satellite imagery. The image was acquired by the Landsat 7 satellite. The top view is a standard panchromatic (visible and near infrared) satellite picture. The bottom view is the same scene projected into an anaglyph, based upon SRTM data. Anaglyphs are generated by creating two differing perspectives of a single satellite image, one perspective for each eye. Note that there are several dark lines crossing parts of the image. Some of these lines are roads but some are geologic dikes. Dikes are sheet-like rocks formed when volcanic fluids intrude cracks in older host rocks. The intersections of these "sheets" with the topographic surface appear as linear or curvilinear traces across the terrain. The dikes traverse varied terrains and they intersect each other - much like roads. In the two dimensional view, roads and dikes are confusingly similar in appearance. However, in three dimensions, dikes can be seen to be ridge-forming features and geographically related to other geologic features (left and lower right of image). In contrast, roads generally traverse less rugged terrain and pass through ridge gaps(upper right and left center of image). Thus the added topographic information provided by SRTM greatly helps in the image interpretation.

Orientation: looking East Image Data: Landsat Bands 5, 4, 3 as red, green, blue respectively Original Data Resolution: SRTM 30 meters (99 feet) Date Acquired: four days in February, 2000 (SRTM), February 9, 2001 (Landsat), This perspective view shows the city of Bhuj, India, in the foreground near the right side (dark gray area). Bhuj and many other towns and cities nearby were almost completely destroyed by the January 26, 2001, earthquake in western India. This magnitude 7.6 earthquake was the deadliest in the history of India with some 20,000 fatalities and over a million homes damaged or destroyed. The epicenter of the earthquake was in the area in the upper left corner of this view. The city of Anjar is in the dark gray area near the top center of the image. Anjar was previously damaged by a magnitude 6.1 earthquake in 1956 that killed 152 people and suffered again in the larger 2001 earthquake. The red hills to the left of the center of the image are the Has and Karo Hills, which reach up to 300 meter (900 feet) elevation. These hills are formed by folded red sandstone layers. Geologists are studying these folded layers to determine if they are related to the fault that broke in the 2001 earthquake. The city of Bhuj was the historical capital of the Kachchh region. Highways and rivers appear as dark lines. Vegetation appears bright green in this false-color Landsat image. The Gulf of Kachchh (or Kutch) is the blue area in the upper right corner of the image, and the gray area on the left side of the image is called the Banni plains. This three-dimensional perspective view was generated using topographic data from the Shuttle Radar Topography Mission (SRTM) and an enhanced false-color Landsat 7 satellite image. Colors are from Landsat bands 5, 4, and 2 as red, green and blue, respectively. Topographic expression is exaggerated 5X.

SRTM Perspective View with Landsat Overlay: Mt. Pinos, California |
| Description |
Prominently displayed in this image, Mt. Pinos, at 2,692 meters (8,831 feet) is the highest peak in the Los Padres National Forest. Named for the mantle of pine trees covering its slopes and summit, it offers one of the best stargazing sites in Southern California. Shuttle Radar Topography Mission (SRTM) elevation data were combined with Landsat data to generate this perspective view looking toward the northwest. Not only is the mountain popular with astronomers and astro-photographers, it is also popular for hiking trails and winter sports. The broad low relief area in the right foreground is Cuddy Valley. Cuddy Valley Road is the bright line on the right (north)side of the valley. Just to the left and paralleling the road is a scarp (cliff) formed by the San Andreas fault. The fault slices through the mountains here and then bends and continues onto the Carrizo Plain (right center horizon). This entire segment of the San Andreas fault broke in a major earthquake in 1857. Landsat has been providing visible and infrared views of the Earth since 1972. SRTM elevation data match the 30-meter(98-foot) resolution of most Landsat images and will substantially help in analyses of the large and growing Landsat image archive. For visualization purposes, topographic heights displayed in this image are exaggerated two times. Colors approximate natural colors. The elevation data used in this image was acquired by SRTM aboard Space Shuttle Endeavour, launched on February 11,2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on Endeavour in 1994. SRTM was designed to collect three-dimensional measurements of Earth's land surface. To collect the 3-D SRTM data, engineers added a mast 60 meters (about 200 feet)long, installed additional C-band and X-band antennas, and improved tracking and navigation devices. The mission is a cooperative project between the NASA, the National Imagery and Mapping Agency (NIMA) of the U.S. Department of Defense, and the German and Italian space agencies. It is managed by NASA's Jet Propulsion Laboratory, Pasadena, Calif., for NASA's Earth Science Enterprise, Washington, D.C. JPL is a division of the California Institute of Technology in Pasadena.

SRTM Perspective View with Landsat Overlay: Rann of Kachchh, India |
| Description |
The earthquake that struck western India on January 26,2001, was the country's strongest in the past 50 years. This perspective view shows the area of the earthquake's epicenter in the lower left corner. The southern Rann of Kachchh appears in the foreground. The Rann is an area of low-lying salt flats that shows up with various shades of white and blue in this false-color Landsat image. The gray area on the middle of the image is called the Banni plains. The darker blue spots and curving lines in the Rann and the Banni plains are features that appeared after the January earthquake. Their true colors are shades of white and gray, but the infrared data used in the image gives them a blue or turquoise color. These features are the effects of liquefaction of wet soil, sand and mud layers caused by the shaking of the earthquake. The liquefaction beneath the surface causes water to be squeezed out at the surface forming mud volcanoes, sand blows and temporary springs. Some of the residents of this dry area were hopeful that they could use the water, but they found that the water was too salty in almost every place where it came to the surface. The city of Bhuj, India, appears as a gray area in the upper right of the image. Bhuj and many other towns and cities nearby were almost completely destroyed by the January 2001 earthquake. This magnitude 7.7 earthquake was the deadliest in the history of India with some 20,000 fatalities and over a million homes damaged or destroyed. The city of Bhuj was the historical capital of the Kachchh region. Highways and rivers appear as dark lines. Vegetation appears bright green in this false-color Landsat image. The city of Anjar is in the dark gray area near the upper left of the image. Previously damaged by a magnitude 6.1 earthquake in 1956 that killed 152people, Anjar suffered again in the larger 2001 earthquake. The red hills in the center of the image are the Has and Karo Hills, which reach up to 300 m (900 feet) elevation. Geologists are studying the folded red sandstone layers that form these hills to determine if they are related to the fault that broke in the 2001 earthquake. This three-dimensional perspective view was generated using topographic data from the Shuttle Radar Topography Mission (SRTM) and an enhanced false-color Landsat 7 satellite image. Colors are from Landsat bands 5, 4, and 2 as red, green and blue, respectively. Topographic expression is exaggerated 5X. Landsat has been providing visible and infrared views of the Earth since 1972. SRTM elevation data matches the 30-meter resolution of most Landsat images and will substantially help in analyses of the large and growing Landsat image archive. The Landsat 7 Thematic Mapper image used here was provided to the SRTM by the United States Geological Survey, Earth Resources Observation Systems(EROS) Data Center, Sioux Falls, South Dakota. Elevation data used in this image was acquired by the Shuttle Radar Topography Mission (SRTM) aboard, the Space Shuttle Endeavour, launched on February 11,2000.

SRTM Perspective View with Landsat Overlay: Santa Barbara Coastline, California |
| Description |
This image of the Santa Barbara, California, region provides a beautiful snapshot of the area's rugged mountains and long and varied coastline. Generated using data acquired from the Shuttle Radar Topography Mission (SRTM) and an enhanced Landsat image this is a perspective view toward the northeast, from the Goleta Valley in the foreground to a snow-capped Mount Abel (elevation 2,526 m or 8,286 feet) along the skyline at the left. On a clear day, a pilot might see a similar view shortly before touching down on the east-west runway of the Santa Barbara Airport, seen just to the left of the coastline near the center of image. This area is one of the few places along the U.S. West Coast where because of a south-facing beach, fall and winter sunrises occur over the ocean. Landsat has been providing visible and infrared views of the Earth since 1972.

SRTM Stereo Pair: Haro and Kas Hills, India |
| Description |
February 11,2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. SRTM was designed to collect three-dimensional measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter-long (200-foot) mast, installed additional C-band and X-band antennas, and improved tracking and navigation devices. The mission is a cooperative project between the National Aeronautics and Space Administration (NASA), the National Imagery and Mapping Agency (NIMA) of the U.S. Department of Defense(DoD), and the German and Italian space agencies. It is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Earth Science Enterprise,Washington, DC. Size: 22.3 x 14.3 kilometers ( 13.8 x 8.9 miles) Location: 23.4 deg. North lat., 69.8 deg. East lon. Orientation: North toward the top Image Data: Landsat Bands 1, 2+4, 3 as blue, green, red, respectively Date Acquired: February 2000 (SRTM), February 9, 2001 (Landsat), On January 26, 2001 the Kachchh region in western India suffered the most deadly earthquake in India's history. This stereoscopic view of landforms northeast of the city of Bhuj depicts geologic structures that are of interest in the study the tectonic processes that may have led to that earthquake. However, preliminary field studies indicate that these structures are composed of Mesozoic rocks that are overlain by younger rocks showing little deformation. Thus these structures may be old, not actively growing, and not directly related to the recent earthquake. The Haro Hills are on the left and the Kas Hills are on the right. The Haro Hills are an "anticline," which is an upwardly convex elongated fold of layered rocks. The anticline is distinctly ringed by an erosion resistant layer of sandstone. The east-west orientation of the anticline may relate to the crustal compression that has occurred during India's northward movement toward, and collision with, Asia. In contrast, the largest of the Kas Hills appears to be a tilted (to the south) and faulted (on the north) block of layered rocks. Also seen here, the curvilinear ridge trending toward the southwest from the image center is an erosion resistant "dike," which is an igneous intrusion into older "host" rocks along a fault plane or other crack. The dike also appears to extend northeast from the image center as a dark line having very little topography. Its location between the tilted block and a smaller anticline to the north (directly east of the larger anticline) probably indicates that the dike fills the fault that separates these contrasting geologic structures. These features are simple examples of how digital elevation data can stereoscopically enhance satellite imagery to provide a direct input to geologic studies. This stereoscopic image was generated by draping a Landsat satellite image(taken just two weeks after the earthquake) over a preliminary Shuttle Radar Topography Mission (SRTM) elevation model. Two differing perspectives were then calculated, one for each eye. They can be seen in 3-D by viewing the left image with the right eye and the right image with the left eye (cross-eyed viewing), or by downloading and printing the image pair and viewing them with a stereoscope. When stereoscopically merged, the result is a vertically exaggerated view of the Earth's surface in its full three dimensions. Landsat has been providing visible and infrared views of the Earth since 1972. SRTM elevation data matches the 30-meter resolution of most Landsat images and will substantially help in analyses of the large and growing Landsat image archive.

STS-99 crew exits the O&C enroute to Launch Pad 39A |
| Description |
The STS-99 crew wave to onlookers as they walk to the astrovan which will take them to Launch Pad 39A and liftoff of Space Shuttle Endeavour, targeted for 12:47 p.m. EST. In their orange launch and entry suits, they are (foreground) Pilot Dominic Gorie and Commander Kevin Kregel. Behind them (left to right) are Mission Specialists Janice Voss (Ph.D.), Mamoru Mohri (Ph.D.), Gerhard Thiele and Janet Lynn Kavandi (Ph.D.). Mohri is with the National Space Development Agency (NASDA) of Japan, and Thiele is with the European Space Agency. The SRTM will chart a new course to produce unrivaled 3-D images of the Earth's surface, using two antennae and a 200-foot-long section of space station-derived mast protruding from the payload bay. The result of the Shuttle Radar Topography Mission could be close to 1 trillion measurements of the Earth's topography. Besides contributing to the production of better maps, these measurements could lead to improved water drainage modeling, more realistic flight simulators, better locations for cell phone towers, and enhanced navigation safety. The mission is expected to last about 11days, with Endeavour landing at KSC Friday, Feb. 11, at 4:55 p.m. EST. |
