| Description |
The earthquake that struck western India on January 26, 2001, was the country's strongest in the past 50 years. This perspective view from NASA's Shuttle Radar Topography Mission (SRTM) 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 in 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 152 people, 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 meters (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 (98-foot) 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 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, Calif., for NASA's Earth Science Enterprise, Washington, D.C. Image: NASA/JPL/NIMA |

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. Original Data Resolution: 30 meters (99 feet). Vertical Exaggeration: 3 times. |

Lake Mead Shrinks!
| Title |
Lake Mead Shrinks! |
| Abstract |
Lake Mead reservoir is nestled between Arizona and Nevada and runs up to the Hoover Dam. The reservoir stores Colorado River water and supplies it to farms, homes and business in Southern Nevada, Arizona, southern California and northern Mexico. Scientists at NASA are releasing dramatic pictures of the dwindling water supplies in the drought-stricken western United States. According to the Bureau of Reclamation, the Colorado Basin is in its fourth year of drought and computer models project water levels will go down another 15 to 20 feet (4.6 to 6.1 m) by next year. Despite low water levels, The National Park Service says there is still plenty of water for recreation. The Landsat 7 satellite captured images of Lake Mead May 2000, and May 2003. The 2003 image clearly shows a shrinking lake. |

Hurricane Katrina Floods the Southeastern United States |
| Description |
Although the Mississippi River undulates across the bottom of these images virtually unchanged, big changes are visible within the city of New Orleans on August 30, 2005 (top image), compared to April 26, 2000 (bottom.). In 2000, the urban landscape appears in lavender (developed areas) and pale green (springtime vegetation). The city neatly separates the blue ribbon of the Mississippi from Lake Pontchartrain to the north, although several narrow canals are visible as straight blue lines, such as the ones surrounding City Park. In the wake of Katrina, standing water creates a blue, bruised appearance to large sections of the city, especially the eastern part. New Orleans sits in a low-lying area between Lake Pontchartrain to the north and the Mississippi River to the south. When storm surge and heavy rainfall from Hurricane Katrina weakened some levees—hills of earth that line the lake shores, the river, and canal banks—gravity took its course. Water was still flowing from Pontchartrain into New Orleans as of August 31, and many houses were swamped up to their rooftops. Among the locations being slowly inundated are the Superdome, where tens of thousands of refugees are staying, and the French Quarter, which was thought to be one of least flood-prone areas of the city. As the waters build, the risk of people coming into contact with chemical- or sewage-contaminated water increases rapidly.

Hurricane Katrina Floods the Southeastern United States |
| Description |
The floods that buried up to 80 percent of New Orleans had noticeably subsided by September 15, 2005, when the top image was taken by the Landsat 7 satellite. In the two and a half weeks that had passed since Hurricane Katrina flooded the city, pumps had been working nonstop to return the water to Lake Pontchartrain. As portable pumps were brought in to supplement the permanent pumps already hard at work, as much as 380 cubic meters (380,975 liters or 11,300 cubic inches) of water were being pumped out of New Orleans every second, according to the U.S. Army Corps of Engineers [ http://www.hq.usace.army.mil/cepa/katrina/pumps/pumps.html ]. The progress in draining the city is evident when the September 15 image is compared with an image taken one week earlier. In the lower image, taken by the Landsat 5 satellite on September 7, black flood water covers much of the city. By September 15, the dark flood water had all but disappeared, lingering only in a few sections of the city. The September 7 image does not show the full extent of the flooding. Taken more than a week after the hurricane struck New Orleans, the image shows a flooded city that had already started to drain. In a similar (but cloudy) image taken on August 30 [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13094 ], the flood water in St. Bernard Parish, image right, extends almost to the Mississippi River.

Fires In Alaska and Northern Canada |
| Description |
This colorful image shows the fires in east-central Alaska and west-central Yukon Territory, Canada, on June 30, 2004. The area shown is located to the south and east of the Yukon-Charley Rivers National Preserve. To make the image, scientists add color to electromagnetic energy that Landsat is able to detect, but that our eyes cannot normally see. So, for example, infrared energy (heat) appears bright pink around the perimeters of actively burning fires, while burned areas appear a deeper pink. Bare ground or low vegetation appears orange, while vegetation appears in shades of green. The blue river running diagonally across the scene is the Yukon. This false-color composite uses data from shortwave infrared, infrared, and green wavelengths (ETM+ bands 7, 4, and 2). The image has been gap-filled to correct for the failure of the Scan Line Corrector (SLC) on Landsat's Enhanced Thematic Mapper Plus (ETM+) instrument.

Fires in Wyoming and South Dakota |
| Description |
Burning next door to the South Dakota towns of Deadwood and Lead, the Grizzly Gulch fire forced the evacuation of many residents in the first week of July, 2002. In addition, smoke closed many of the roads in the area. At the time the fire?s behavior was extreme, with ?torching, spotting, and running.? In other words, the fire was primarily burning along the ground, with entire trees occasionally erupting into flame (torching). At the same time, burning embers were being thrown ahead of the fire (spotting). In some areas the fire was spreading from the crown of one tree to another (running). (This glossary of fire terms [ http://www.fs.fed.us/r6/mbs/fire/glossary.html ] has a good list of definitions) The above image shows the fire on the morning of July 1, 2002. Actively burning areas, concentrated on the east (right) side of the fire, are colored red and orange. Dark red areas indicate burn scars, while forest and other vegetation appears green. The exposed rock of the Homestake gold mine, now the National Underground Science Laboratory, [ http://earthobservatory.nasa.gov/cgi-bin/redirect?http://mocha.phys.washington.edu//NUSL/ ] is pinkish-brown. The total extent of the fire is oulined in yellow. The image was acquired by the Enhanced Thematic Mapper plus (ETM+) aboard the Landsat 7 [ http://earthobservatory.nasa.gov/cgi-bin/redirect?http://landsat.gsfc.nasa.gov/ ] satellite. More news about current wildfires in the United States is available from the National Fire Information Center.

Tornadoes Strike Northern Wisconsin |
| Description |
A series of tornadoes ripped through the Upper Midwest region of the United States in the evening of June 7, 2007. At least five different tornadoes touched down in Wisconsin, according to the Associated Press, one of which tore through the Bear Paw Resort in northern Wisconsin. Despite dropping as much as fifteen centimeters (six inches) of rain in some places and baseball-size hail in others, authorities were reporting no deaths attributable to the storm system, and only a smattering of injuries, but considerable property damage in some areas. The Enhanced Thematic Mapper Plus (ETM+) instrument on Landsat 7 examined the tornado damage on June 15, 2007. This natural-color image shows the area around the Wolf River and Bear Paw Resort just north of the Menominee Indian Reservation. The diagonal slash across the landscape from one of the tornadoes is quite dramatic in this full-resolution image, which discerns details as small as 28.5 meters (95 feet), including roads such as Wisconsin Route 55 and the Wolf River, a favorite whitewater river for kayakers. The wide, bare swath of destruction from the tornado is very evident here, where trees were torn down by winds, leaves stripped from their branches, or where agricultural fields outside the Reservation were flattened.

Fires on Hispaniola
| Title |
Fires on Hispaniola |
| Description |
Since March 14, 2005, at least two large fires have been burning in the Cordillera Central, the mountains that run down the spine of Hispaniola. The fires started in the José del Carmen Ariza National Park, on the lower reaches of Pico Duarte, the highest mountain in the Dominican Republic. The flames raced up the mountain, consuming the pine, palm, and broadleaf rainforests that grow at higher elevations. Local news reports say that more than 700 people have gathered to fight the flames, and the government is requesting firefighting airplanes from the United States. The fires were still burning when Landsat 7 ETM+ captured this image on March 21, 2005. The newly burned mountain slopes are dark brown, while unburned forest is green. The image is a false-color image (opposed to a photograph-like image) created from light in the shortwave infrared, near infrared, and green wavelengths. The hot fire fronts glow red in the infrared bands, revealing the extent of the active fire on March 21. Thick smoke, tinted blue in this image, rises from the fires. The highest elevations of Pico Duarte where the fires are burning are covered with rare mountain cloud forests, rainforests that draw water from the clouds. Because the forests can take water directly from the sky, they play an important role in providing water to the Dominican Republic, particularly during the dry season, which runs from December to May. The headwaters of 17 of the country?s rivers can be found in the Cordillera Central. These rivers are used for drinking water, irrigation, and to produce energy. In March 2005, the forests have been particularly prone to large fires. An unusually severe dry season dried the vegetation on Hispaniola, making the region susceptible to fire. Officials don?t know how these fires started, but dry weather has probably contributed to the severity of the fires. NASA image created by Jesse Allen, Earth Observatory, using data provided courtesy of the Landsat Project Science Office. |

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. 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.

It is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Earth Science Enterprise,Washington, DC. Size: 13.8 x 9.6 kilometers ( 8.6 x 5.9 miles) Location: 23.2 deg. North lat., 69.8 deg. East lon. 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. 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(33-yard) 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. 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 |

SRTM Perspective View with Landsat Overlay: Bhuj and Anjar, India |
| Description |
Science Enterprise,Washington, DC. Size: scale varies in this perspective image Location: 23.4 deg. North lat., 69.8 deg. East lon. 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. 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.

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.

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. 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.
