Asavyo Volcano — Ethiopia

Asavyo, also known as Bara’Ale, is the SW-most of three large silicic stratovolcanoes (along with Mallahle and Nabro) constructed along a NE-SW-trending line in the Danakil horst. A large 12-km-wide caldera truncates the summit. Basaltic lava flows cover the flanks, which merge into the Mogorros plains to the south. Although the age of the volcano is not known precisely, Asavyo was considered to have erupted during last 2,000 years (IAVCEI, 1973). A large post-caldera cone was constructed near the center of the caldera, and smaller pyroclastic cones occur within the caldera and on its flanks.
