| Title |
Iceland Glacier Recession 1997 to 2000 |
| Abstract |
This animation is a close up zoom into largest area of glacier recesion at the Breidamerkurjokull glacier in Iceland. The data from 1997 is taken from Landsat 5 and the 2000 data is from Landsat 7. The Breidamerkurjokull glacier in Iceland has been measured by Landsat to be receding since 1973. In 1997, Landsat 5 took several other images of the glacier. It was thought by some glacierologists that this particular glacier was receding quicker in the late 1990s than it did in the late 1980s or 1970s. After careful analysis Goddard's Glacierologist, Dorothy Hall, concluded that the recession from 1997 to 2000 occurs at a similar rate to the recession between 1973 and 2000. It is extremely controversial whether or not this recession is caused by global warming. |

| Title |
Mt. St. Helens from Landsat: 1973 to 1992 |
| Abstract |
These images show Mt. St. Helens almost a decade before the May 18, 1980, eruption, approximately three years after the eruption, then a pair of images over the following decade, as the landscape recovered. Notice in particular the area northwest of the mountain, past the Toutle River, where forest coverage has recovered somewhat in the past ten years. North is up in all these images. The 1973 Landsat 1 image used MSS bands 7, 5, and 4 (called MSS 4, 2, and 1 on the later Landsat satellites) displayed as red, green, and blue respectively. The other images mapped TM bands 4, 3, and 2 to red, green, and blue. This color combination is often referred to as 'false color infrared' since it has a similar appearance and tone to color infrared photography. Reds represent vegetation (which is a strong reflector of near infrared light), greys are exposed land, and light blues show snow on the peaks of Mt. St. Helens and neighboring Mt. Adams. The Columbia River snakes into view in the lower left corner, just north of Portland, Oregon. |

…
| Title |
Cucharas Canyon & Spanish Peaks, Colorado |
| 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. The Landsat Thematic Mapper image used here came from an on-line mosaic of Landsat images for the continental United States (http://mapus.jpl.nasa.gov), a part of NASA's Digital Earth effort.*Size:* scale varies in this perspective image *Location:* 37.5 deg. North lat., 104 deg. East lon. *Orientation:* looking southwest *Image Data:* Landsat Bands 5, 4, 3 as red, green, blue, respectively *Original Data Resolution:* SRTM 1 arcsecond (30 meters or 99 feet), Thematic Mapper 1 arcsecond (30 meters or 99 feet) *Date Acquired:* February 2000 (SRTM) Image courtesy NASA/JPL/NIMA/USGS |

Deadly Tornado Rips Across I

| Title |
Deadly Tornado Rips Across Indiana and Kentucky |
| Description |
A large tornado cut a 66-kilometer (41-mile) swath of destruction across southern Indiana and northwestern Kentucky in the early morning hours of November 6, 2005. The tornado killed 23 and left at least 200 injured. Ranked a strong F2 or weak F3 on the Fujita Tornado Damage Scale [ http://www.spc.noaa.gov/faq/tornado/f-scale.html ], the storm destroyed more than 100 buildings and homes as it tore across the two states with winds estimated at 320 kilometers per hour (200 miles per hour) at about 2 a.m. Central Standard Time. Four days later, on November 10, 2005, the Landsat 5 satellite captured this image of the storm-hit section of Indiana and Kentucky. A pale, interrupted stripe across the image—like someone dragged an eraser across the scene—shows the track the tornado made as it moved from southwest to northeast along the outskirts of Evansville, Indiana. The tornado's track begins on the northern banks of the Ohio River on the lower left side of the image. It sliced across Ellis Park, the oval-shaped Churchill Downs horse-racing track, killing at least three horses stabled in the track's barns, the Associated Press reported. The tornado then moved northeast across open fields into the neighborhoods southeast of downtown Evansville. Populated areas are cement white, black, and brown. Here, the contrast between the still-standing structures and the white swath of destruction becomes greater, making the tornado track easier to follow. Every year, some 1,000 tornadoes strike the United States, though their toll has decreased as weather forecasts and warning systems have improved. The November 6 tornado was the deadliest to date in 2005. To learn more about tornado safety, please visit the National Oceanic and Atmospheric Administration's National Weather Service [ http://www.crh.noaa.gov/pah/1925/gi_body.php#TORNADO%20SAFETY%20INFORMATION ] web site. The National Weather Service's Weather Forecast Office [ http://www.crh.noaa.gov/pah/?n=evansvilletornado-nov.6,2005 ] also provides an analysis of the November 6 tornado, including photos.

The Atlantic?s powerful waters gouged a new inlet across Hatteras Island in North Carolina?s Outer Banks on September 18, 2003 when Hurricane Isabel came ashore. The top image, taken by the Landsat 5 satellite on September 26, 2003, shows how the storm split Hatteras Island into two. The bottom image, taken on October 25, 1999, shows the southern tip of Hatteras Island before Isabel wrought her damage. The inlet cut across Highway 12 near a section of Cape Hatteras National Seashore Park, to the right of the break in the top image. The park houses the famous Cape Hatteras Lighthouse. Cape Hatteras Village to the south of the break on the green pointed section of land (left) is now isolated from the rest of the island.

Hurricane Katrina Erodes the U.S. Gulf Coast |
| Description |
The graceful curve of the Chandeleur Islands resembles a multi-boned spine connecting the Mississippi Gulf coast to the delta of the Mississippi River in Louisiana. Like all barrier islands, the Chandeleur Islands form a thin protective wall between the open sea and the mainland, in this case Louisiana's St. Bernard Parish. The islands absorb the strongest waves, sheltering the mainland during large storms. It is no surprise, then, that barrier islands along the U.S. Gulf Coast changed dramatically in the wake of Hurricane Katrina, and no change is as dramatic as that seen in the Chandeleur Islands. Hurricane Katrina's strong winds, storm surge, and battering waves scoured the islands, leaving them reduced or gone altogether. These images of the islands were taken by the Landsat 5 satellite. The top image, taken on September 16, 2005, shows the Mississippi and Alabama coast line, including the line of islands that bore the brunt of Katrina's fury. The lower images show the northern section of the Chandeleur Islands at full resolution. In the 11 months that passed between October 15, 2004, when the right image was taken, and September 16, 2005, when the left image was taken, the islands have wasted away. Barrier islands like the Chandeleur Islands are constantly building, eroding, and shifting under the normal actions of wind and waves. A powerful storm like Katrina can produce changes that otherwise may have taken many years, and most of the change seen here is probably a result of Katrina. Hurricane Dennis also gave the islands a glancing blow on July 10, 2005, and may be responsible for some of the change. The other barrier islands shown in the top image were also scoured by Katrina. The large images show that the Ship Islands [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13130 ] are now significantly smaller than they were in 2004, and Dauphin Island [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13132 ] has been cut in two.

| Title |
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.

Esperanza Fire
| Title |
Esperanza Fire |
| Description |
In late October, a fierce forest fire flared up in the mountainous terrain west of Palm Springs, California. The Esperanza Fire started in the foothills at the southern outskirts of the town of Cabazon, apparently as an act of arson. Driven by Santa Ana winds out of Great Basin deserts to the east, the fire raced over more than 40,000 acres in a matter of days, destroying 34 homes and 20 outbuildings in the area. Several firefighters died while battling the blaze.This high-resolution satellite image of the fire was captured on October 26, 2006, by the Thematic Mapper sensor on NASA's Landsat 5 satellite. The image was captured at 11:16 a.m. Pacific Daylight Time, roughly 10 hours after fire officials believe the fire began. At the top of the scene, the towns of Banning and Cabazon line Interstate 10, which appears as a thick, gray ribbon running through the dry, brown valley of San Gorgino Pass. Regular geometric shapes—straight lines and rectangles—are roads and buildings. Meandering, pale tracings show the paths of dry creeks and rivers. To the south, the foothill ranges of the San Jacinto Mountains begin. Fire was burning along ridgelines near McMullen and Hurley Flats. Gray-brown smoke stretches southwest in long plumes. A towering column of smoke west-southwest of McMullen flat casts a dramatic black shadow to the northwest. At the time of this image, the fire had already burned almost the entire landscape between Hurley Flat and the valley floor to the north, as well as nearly all the terrain bounded by the smoke plumes. Although the difference is subtle, burned areas appear charcoal-tinged when compared to unburned vegetation, such as the forested slopes of the Black Mountain Scenic Area at lower right. Unburned vegetation appears brownish-green. NASA image created by Jesse Allen, Earth Observatory, using data provided courtesy of Laura Rocchio, Landsat Project Science Office.

Mount St. Helens
| Title |
Mount St. Helens |
| Description |
The tip of Mount St. Helens glowed red when the Landsat 5 satellite passed overhead on October 14, 2004. At the time, the volcano was at alert level 2 in a three level warning system, level two indicates that the volcano is restless and may erupt at any time, but an eruption is not imminent. By this time, hot lava had broken to the surface of the growing lava dome inside the crater. The red dot seen here actually represents pixels that were saturated in Landsat's thermal bands and corresponds to the lava seeping out of the lava dome. The false-color image also emphasizes the contrast between the lush temperate forests and farmland and the lava and ash covered volcano. In this image, all vegetation is bright green and bare land is grey and tan. Spirit Lake is the black lake northeast of the volcano.

Perspective View, Mount Shasta, California |
| Description |
At more than 4,300 meters (14,000 feet ), Mount Shasta is California?s tallest volcano and part of the Cascade chain of volcanoes extending south from Washington. This computer-generated perspective viewed from the west also includes Shastina, a slightly smaller volcanic cone left of Shasta?s summit and Black Butte, another volcano in the right foreground. This 3-D perspective view was generated using topographic data from the Shuttle Radar Topography Mission [ http://earthobservatory.nasa.gov/cgi-bin/redirect?http://www.jpl.nasa.gov/srtm/ ] (SRTM) and an enhanced color Landsat 5 satellite image. Topographic expression is exaggerated two times. 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 analyzing the large and growing Landsat image archive. Elevation data used in this image was acquired by the Shuttle Radar Topography Mission (SRTM) aboard the Space Shuttle Endeavour, launched on Feb. 11, 2000. Size: scale varies in this perspective image Location: 41.4 deg. North lat., 122.3 deg. West lon. Orientation: looking east Image Data: Landsat Bands 3,2,1 as red, green, blue, respectively Original Data Resolution: SRTM 1 arcsecond (30 meters or 98 feet), Thematic Mapper 1 arcsecond (30 meters or 98 feet) Date Acquired: February 2000 (SRTM) For more information, read: Pictures from the Real Edge: NASA Posts U.S. Topography Data [ http://earthobservatory.nasa.gov/cgi-bin/redirect?http://www.jpl.nasa.gov/releases/2002/release_2002_19.html ].

Perspective View: San Diego, California |
| Description |
The influence of topography on the growth of the city of San Diego is seen clearly in this computer-generated perspective viewed from the south. The Peninsular Ranges to the east of the city have channeled development of the cities of La Mesa and El Cajon, which can be seen just above the center of the image. San Diego itself clusters around the bay enclosed by Point Loma and Coronado Island. In the mountains to the right, Lower Otay Lake and Sweetwater Reservoir show up as dark patches. This 3-D perspective view was generated using topographic data from the Shuttle Radar Topography Mission (SRTM) and an enhanced color Landsat 5 satellite image. Topographic expression is exaggerated two times. 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 analyzing the large and growing Landsat image archive. Elevation data used in this image was acquired by the Shuttle Radar Topography Mission (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.

Picnic Rock Fire, CO |
| Description |
This image of the Picnic Rock Fire near Ft. Collins, Colorado was taken mid-morning on April 1, 2004 when the fire covered approximately 5,500 acres. Data from the shortwave, near-infrared, and visible portions of the electromagnetic spectrum reveal actively burning areas (yellow and pink pixels). The burn scar appears brown, while fields cleared for planting are tan and emerging crops and grasslands are light green. Developed areas, including Fort Collins in the lower right corner of the image, are purple. By April 7th the fire was 95% contained, and had consumed 8,900 acres in a mostly uninhabited area. The image was acquired by the Thematic Mapper instrument aboard the Landsat [ http://landsat7.usgs.gov/index.php ] 5 satellite.

Fires in Quebec
| Title |
Fires in Quebec |
| Description |
More than 80 fires were triggered by lightning in late May in Quebec. The flaming fronts of wildfires burning in Quebec, Canada, on June 2, 2005, are bright pink in this infrared-enhanced (not ?natural? color) Landsat satellite image. Three fires are visible in the image, emitting bluish smoke plumes that blow eastward. Vegetation is in shades of green, sparsely vegetated or naturally bare soil is pinkish, and burned areas are deep reddish-brown. Water is dark blue to nearly black. The direction of the smoke as well as the fact that fires appear to be burning most actively on their eastern perimeter indicates the wind is blowing from the west. The area shown is in west-central Quebec, to the east of James Bay. NASA image created by Jesse Allen, Earth Observatory, using data provided by the NASA Landsat Project Science Office and the National Center for Earth Resources Observation & Science (NCEROS). |

Sweat Farm Road Fire, Georgi
…
| Title |
Sweat Farm Road Fire, Georgia |
| Description |
Dense plumes of blue-white smoke billowed from the Sweat Farm Road Fire in southern Georgia on April 19, 2007, when the Landsat 5 satellite captured this detailed image. The fire started on April 16, when a tree fell on a power line and, fanned by strong winds, quickly exploded into a major fire. By April 19, the fire had forced officials to close several roads, including U.S. Highway 1, and to evacuate hundreds of people from the perimeter of the city of Waycross, the silver cluster along the top edge of the image. The nearness of the fire is evident in the dark brown, charred land just south of the city. The active fire front is along the south edge of the burned area, where the flames are eating into the dark green hardwood forests, pine plantations, and shrubs in Okefenokee Swamp. Because of the difficult terrain, the fire and the adjoining Big Turnaround Complex fire are expected to burn until significant rain falls, said the morning report issued by the Southern Area Coordination Center [ http://gacc.nifc.gov/sacc/predictive/intelligence/intelligence.htm ] on May 4."In the long term, the burning of the swamp will ultimately benefit the swamp wilderness habitat, which is a fire-dependent ecosystem [ http://www.nifc.gov/preved/comm_guide/wildfire/fire_6.html ]," said a press release [ http://www.fws.gov/okefenokee/BigTurnaroundFire.htm ] issued from the Okefenokee National Wildlife Refuge on May 4. Such ecosystems require fire to remain healthy. In the case of southern pine forests, many pine species need fire to remove litter from the ground and release soil nutrients so that new seedlings can grow. You can download a 28.5-meter-resolution KMZ file of the Sweat Farm Road Fire [ http://earthobservatory.nasa.gov/Newsroom/NewImages/Images/sweatfarmfire_l5_2007109.kmz ] for use with Google Earth.
