The area shown covers parts of Congo, Rwanda and Uganda.Lake Kivu, in the lower left of the image, lies within the East African Rift, an elongated tectonic pull-apart depression in Earth's crust. The rift extends to the northeast as a smooth lava- and sediment-filled trough. Two volcanic complexes are seen in the rift. The one closer to the lake is the Nyiragongo volcano, which erupted in January 2002, sending lava toward the lake shore and through the city of Goma. East of the rift, even more volcanoes are seen. These are the Virunga volcano chain, which is the home of the endangered mountain gorillas. Note that the terrain surrounding the volcanoes is much smoother than the eroding mountains that cover most of this view, such that topography alone is a good indicator of the extent of the lava flows.Elevation data used in this image was acquired by the Shuttle Radar Topography Mission aboard Space Shuttle Endeavour, launched on Feb. 11, 2000. The mission 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. || ", "hits": 216 }, { "id": 14652, "url": "https://svs.gsfc.nasa.gov/14652/", "result_type": "Produced Video", "release_date": "2024-08-15T17:00:00-04:00", "title": "Exploring Volcanoes with NASA’s GEODES Team", "description": "Enjoy this music video of NASA’s GEODES team exploring lunar-like landscapes.Complete transcript available.Music credit: “Aerial” by Ben Cosgrove” and \"Volcano\" by Ben Cosgrove.
