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": 224 }, { "id": 14214, "url": "https://svs.gsfc.nasa.gov/14214/", "result_type": "Produced Video", "release_date": "2022-09-20T00:00:00-04:00", "title": "How NASA Sees the Life Cycle of Volcanic Island Hunga Tonga-Hunga Ha’apai", "description": "Complete transcript available. || HHTH_Final.00001_print.jpg (1024x576) [78.9 KB] || Thumbnail.png (2838x1588) [5.2 MB] || HHTH_Final.00001_searchweb.png (320x180) [66.5 KB] || HHTH_Final.00001_thm.png (80x40) [5.0 KB] || HHTH_Final.webm (1920x1080) [43.1 MB] || HHTH_Final.mp4 (1920x1080) [779.2 MB] || HHTH_Audio_otter_ai.en_US.srt [7.7 KB] || HHTH_Audio_otter_ai.en_US.vtt [7.7 KB] || ", "hits": 111 }, { "id": 4726, "url": "https://svs.gsfc.nasa.gov/4726/", "result_type": "Visualization", "release_date": "2019-03-27T00:00:00-04:00", "title": "New Island forms in Tonga (Updated)", "description": "This visualization shows the evolution Tonga's new island between January 2015 and March 2018. || Tonga_evolutn.1300_print.jpg (1024x576) [129.1 KB] || Tonga_evolutn.1300_searchweb.png (320x180) [84.2 KB] || Tonga_evolutn.1300_web.png (320x180) [84.2 KB] || Tonga_evolutn_Wcredits_1080p30.mp4 (1920x1080) [43.0 MB] || Tonga_evolutn_Wcredits_1080p30_h265.mp4 (1920x1080) [17.9 MB] || Tonga_evolutn_Wcredits_1080p30.webm (1920x1080) [5.8 MB] || Tonga_evolutn_Wcredits_2160p30_h265.mp4 (3840x2160) [50.9 MB] || 3840x2160_16x9_30p (3840x2160) [0 Item(s)] || Tonga_evolutn_Wcredits_2160p30.mp4 (3840x2160) [140.4 MB] || Tonga_evolutn_Wcredits_1080p30_h265.mp4.hwshow || ", "hits": 255 }, { "id": 30988, "url": "https://svs.gsfc.nasa.gov/30988/", "result_type": "Hyperwall Visual", "release_date": "2018-08-29T00:00:00-04:00", "title": "Earth System Diagram", "description": "Diagram showing parts of the Earth system. || earth_system_diagram_print.jpg (1024x574) [115.6 KB] || earth_system_diagram.png (4104x2304) [1.2 MB] || earth_system_diagram_searchweb.png (320x180) [63.5 KB] || earth_system_diagram_thm.png (80x40) [6.6 KB] || earth_system_diagram.hwshow [208 bytes] || ", "hits": 434 }, { "id": 4635, "url": "https://svs.gsfc.nasa.gov/4635/", "result_type": "Visualization", "release_date": "2018-06-15T11:00:00-04:00", "title": "Visualizations of Hunga Tonga Hunga Ha'apai and the Martian Landscape", "description": "In early 2015, a volcanic eruption in the Kingdom of Tonga created a new island informally known as Hunga Tonga Hunga Ha'apai (HTHH).

Next, mantle motions pulled North America westward over Farallon, and the plate scraped along the bottom of the continent - for fifteen hundred kilometers. As North America continued its westward trek, Farallon settled to the bottom of the mantle.The image is output from a model run using the TERRA mantle software.

The feature is believed to have been caused by a short period comet striking at 70 kilometers per second and splattering into the muddy alluvial flood plain in the Lower Amazon jungle. The impact created a circular depression which is now roughly 8 kilometers across and 3 meters deep. The structure was discovered in 1988 Landsat data, but was not visited successfully until 1998 because the region is inaccessible. Future expeditions hope to finally settle if the feature truly is the impact crater it appears to be, and if so, determine the nature of the impactor.

The image was constructed from Landsat Thematic Mapper bands 7, 5, and 3 displayed as red, green, and blue respectively. The green tone of the image distinguishes between different types of vegetation with low scrubland in the alluvial flood plain appears as a light green and dense tropical jungle coverage appearing dark green.
