Mallahle

Stratovolcano · Ethiopia-Eritrea · 1875m

The smaller (left-hand) of the two large calderas at the bottom center of this NASA Space Shuttle image is Mallahle. The steep-walled 8-km-wide caldera truncates a stratovolcano. Basaltic lava flows blanket the slopes of the volcano, and flank vents are most numerous on its western side. Mallahle lies SW of the larger Nabro caldera (right-center) and is the central of three NE-SW-trending stratovolcanoes in the Danakil horst SW of Dubbi volcano.

Geological summary

Mallahle is the central of three NE-SW-trending stratovolcanoes (along with Asavyo and Nabro) in the Danakil horst SW of Dubbi volcano. These volcanoes, plus Sork'Ale, form the Bidu Volcanic Complex. The volcano is truncated by a steep-walled 6-km-wide caldera, and is formed of rhyolitic lava flows and pyroclastics. Basaltic lava flows cover the slopes. Recent obsidian flows are found on the NW flank, 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 cover the countryside.
