Photo Gallery


Chabbi volcano, rising to the north across Awasa lake, is a very large obsidian dome constructed on the SE rim of the 15-km-wide Corbetti caldera, which itself lies within the NW side of the larger Awasa caldera. In this photo Corbetti caldera is out of view behind its southern rim, which forms the low saddle at the left. Lava flows from Chabbi extend into Corbetti caldera. The age of the latest eruption of Corbetti volcano is not known, although fumarolic activity continues.
