Tungurahua Volcano Erupts in Ecuador |
| Description |
Rising to an altitude of 16,475 feet (5,023 meters), the Tungurahua Volcano towers over the surrounding terrain in central Ecuador. From this Moderate Resolution Imaging Spectroradiometer (MODIS) image from the Terra satellite, it?s easy to see why this volcano (center) is also called the ?Black Giant??its flanks are coated with dark lava flows. In this scene, captured on January 14, 2004, a plume of ash is rising from the volcano and is stretching northeastward across the Andes and the lower elevations to the east. According to reports from the Smithsonian?s Global Volcanism Program, Tungurahua began erupting with plumes of ash, steam, and smoke at the end of December 2003 and has continued into the third week of January 2004. The high-resolution image captured a wider area. Some of the haze visible amid the clouds to the south of Tungurahua may be the remains of smoke and ash plumes from Ecuador?s larger Sangay Volcano, which was also reported to be erupting with small ash plumes during this period.

Tungurahua Volcano in Ecuador |
| Description |
Tungurahua Volcano in Ecuador emitted a volcanic plume of ash and/or steam on June 24, 2006. The Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov/ ] flying onboard NASA's Terra [ http://terra.nasa.gov/ ] satellite took this picture the same day. In this image, the volcanic plume appears in a shade of pale gray, slightly darker than the nearby clouds that are bright white. The plume blows westward toward the neighboring dormant volcano Chimborazo [ http://earthobservatory.nasa.gov/Newsroom/NewImages/images.php3?img_id=17121 ], which sports a snowcap at its summit. Nearby settlements include Rio Bamba and Ambato. NASA image created by Jesse Allen, Earth Observatory, using data obtained from the Goddard Earth Sciences DAAC. [ http://daac.gsfc.nasa.gov/ ] |

Tungurahua Volcano in Ecuador |
| Description |
When the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov/ ] flying onboard NASA's Terra [ http://terra.nasa.gov/ ] satellite took this picture on July 17, 2006, Tungurahua Volcano was ejecting gas and ash for the fourth consecutive day. This burst of activity proved to be the volcano's most powerful since 1999, according to Reuters. Besides volcanic ash and gas, the volcano produced molten rock that set fire to local vegetation. By July 18, the volcano's activity had blocked roads, ruined bridges, covered nearby villages in ash, killed livestock, and prompted evacuations. Despite fears for their own safety, however, some villagers returned home to salvage some of their property. The BBC provided photos [ http://news.bbc.co.uk/2/hi/in_pictures/5184258.stm ] of the event on July 16, 2006. These images show Tungurahua and its neighbor, Chimborazo [ http://earthobservatory.nasa.gov/Newsroom/NewImages/images.php3?img_id=17121 ]. The top image shows part of the bottom image in greater detail. A gray-brown plume of volcanic ash and/or steam emanates from Tungurahua, mingling with nearby white clouds. The volcanic plume appears to spread out in all directions near the summit then blow generally westward toward Chimborazo.

Tungurahua Volcano in Ecuador |
| Description |
Dozens of people were missing, hundreds of families were evacuated, and three villages were gone in the wake of an eruption of the Tungurahua Volcano in mid-August 2006. A month earlier, the volcano affected [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13716 ] nearby residents and agriculture, but this eruption was worse. According to news reports, a serious eruption began on August 16, 2006, sending a column of volcanic ash 8 kilometers (5 miles) into the sky and raining lava and hot rocks on the surrounding area. Nothing remained of the villages of Chilibu, Choglontuz, and Palitagua, and the flow of lava and molten rock blocked the Patate, Puela, and Chambo Rivers. As of August 18, at least five people had died, and more casualties were expected. The Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov/ ] flying onboard NASA's Terra [ http://terra.nasa.gov/ ] satellite took a picture of the region on August 17, 2006. It appears at top, and a Blue Marble [ http://earthobservatory.nasa.gov/Newsroom/BlueMarble/ ] image of the area from August 2004 appears at bottom, for comparison. The Blue Marble image is a composite of images collected over a month. In cloudy regions, monthly composites are necessary to compile cloud-free images. Clouds filled the sky a day after the Tungurahua eruption, but damage was still apparent. The dark brown smudges likely result from volcanic ash from the volcano. One smudge, over 100 kilometers in length, appears in the west, mixed with clouds. A less discernible smudge appears in the east, where relatively clearer skies allow some of the dark land surface to show through. One of Ecuador's most active volcanoes, Tungurahua [ http://www.volcano.si.edu/world/volcano.cfm?vnum=1502-08= ] has a long history of building up edifices and later collapsing them with spectacular eruptions. Although the slopes of a volcano can be a dangerous place to live, many people take the risk [ http://earthobservatory.nasa.gov/Study/NatHazards/ ] because of the rich soils and the fairly mild temperatures that come with high altitude. This tradeoff placed thousands in harm's way when Tungurahua erupted in the summer of 2006. Marked in the bottom image, Tungurahua's neighbor, Chimborazo, [ http://earthobservatory.nasa.gov/Newsroom/NewImages/images.php3?img_id=17121 ] is a dormant volcano that beckons many modern mountaineers. Also marked is Ecuador's capital city of Quito. NASA images created by Jesse Allen and Reto Stöckli, Earth Observatory.

Tungurahua Volcano in Ecuador |
| Description |
The Tungurahua Volcano in Ecuador emitted a plume of volcanic ash in late October 2006. The Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured this image on October 25, 2006. Several days earlier, an eruption of lava and ash forced the evacuation of some 300 local villagers, according to news reports. In this image, a plume of volcanic ash blows westward from the volcano's summit, fanning out as it goes. The plume is fairly dark, suggesting that its contents are fairly high in ash, as opposed to a white plume, which would have more water. One of Ecuador's most active volcanoes, Tungurahua [ http://www.volcano.si.edu/world/volcano.cfm?vnum=1502-08= ] is a stratovolcano composed of alternating layers of hardened lava, ash, and rock. It underwent a major eruption from 1916 to 1918. Another major eruption in 1995 forced the temporary evacuation of a nearby city. An eruption in the summer of 2006 caused widespread crop damage, forced evacuations, and claimed several lives. A 250-meter-resolution KMZ file [ http://earthobservatory.nasa.gov/NaturalHazards/Archive/Oct2006/tungurahua_tmo_2006298.kmz ] of Tungurahua is available for use with Google Earth.

Tungurahua Volcano in Ecuador |
| Description |
The Tungurahua Volcano in Ecuador underwent a severe eruption in August 2006, [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13791 ] followed by intermittent eruptive activity over the next couple months. On October 16, 2006, the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) [ http://asterweb.jpl.nasa.gov ] on NASA's Terra [ http://terra.nasa.gov ] satellite captured this image of the volcano as it released a plume of volcanic ash. This false-color image was created by combining shortwave infrared, near-infrared, and green wavelengths of light observed by ASTER. The image clearly shows not only current volcanic activity, but also the results of earlier eruptions. Deep purple rivulets of rock carve through the bright green vegetation. The rock results from previous lava flows that later solidified. Similar in color to the hardened lava are geometric patches of bare ground on the volcano's slopes, some of the numerous settlements in the area. The Chambo River makes a bright blue ribbon along the western edge of the volcano. Pyroclastic flows of rocks, ash, and other volcanic materials temporarily dammed the Chambo River in August 2006, and the purple remains of earlier eruptions cross this river in the west and the north. At the volcano's summit is a glowing red dot, indicating an area of intense heat. The ash cloud in this image appears bright purple, in contrast with the white clouds to the northwest.

| Title |
Shrimp Farms, Ecuador |
| Original Caption Released with Image |
In many parts of the world, wetlands are being converted to shrimp ponds in order to farm these crustaceans for food and sale. One example is on the west coast of Ecuador, south of Guayaquil. The 1991 Landsat image on top shows a coastal area where 143 square kilometers of wetlands were converted to shrimp ponds. By the time ASTER acquired the bottom image in 2001, 243 square kilometers had been converted, eliminating 83% of the wetlands. These scenes cover an area of 30 x 31 km, and are centered near 3.4 degrees south latitude and 80.2 degrees west longitude. With its 14 spectral bands from the visible to the thermal infrared wavelength region, and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER images Earth to map and monitor the changing surface of our planet. ASTER is one of five Earth-observing instruments launched December 18, 1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products. The broad spectral coverage and high spectral resolution of ASTER provides scientists in numerous disciplines with critical information for surface mapping, and monitoring of dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats, monitoring potentially active volcanoes, identifying crop stress, determining cloud morphology and physical properties, wetlands evaluation, thermal pollution monitoring, coral reef degradation, surface temperature mapping of soils and geology, and measuring surface heat balance. The U.S. science team is located at NASA's Jet Propulsion Laboratory, Pasadena, Calif. The Terra mission is part of NASA's Science Mission Directorate. Size: 30 by 31 kilometers (18.6 by 19.2 miles) Location: 3.4 degrees South latitude, 80.2 degrees West longitude Orientation: North at top Image Data: Landsat bands 4,3 and 2, ASTER bands 3, 2, and 1 Original Data Resolution: Landsat 30 meters (24.6 feet), ASTER 15 meters (49.2 feet) Dates Acquired: Landsat: April 29, 1991, ASTER March 31, 2001 |
