The densely forested Tepi basaltic shield volcano lies about 300 km west of the Ethiopian Rift in southern Ethiopia. A small crater near the center of this NASA Landsat image (with north to the top) is one of many features on this broad volcano. Lava flows have traveled down pre-existing valleys, and there are active hot springs. The smoke plume at the right is from a vegetation fire.

NASA Landsat 7 image (worldwind.arc.nasa.gov) The slopes of Dabbahu volcano in the background are part of a large volcanic massif consisting of obsidian flows, lava domes, cones, and basaltic lava flows constructed on a shield volcano. This view from the N with people for scale shows Da'Ure, a 500-m-long fissure vent formed during the first historical eruption in September 2005. A small dome was formed during the eruption. The central part of the volcano lies farther to the right off the margin of the photo.
