Backgroundfrom Smithsonian / GVP Mallahle volcano information:
The complex Mallahle stratovolcano is truncated by a steep-walled 6-km-wide caldera. Mallahle is formed of rhyolitic lava flows and pyroclastics. Basaltic lava flows blanket the slopes of the volcano.
Recent obsidian flows are found on the NW flank of Mallahle and older obsidian flows were erupted on the northern caldera floor. Flank spatter and scoria cones are most numerous on the western side of the volcano.
Extensive ignimbrite deposits associated with the collapse of Mallahle and Nabro volcanoes blanket the countryside.
