Stratovolcano
Mallahle volcano is located in northern Ethiopia near the border with Eritrea. The volcano contains a circular caldera with a diameter of 6 km. The caldera floor tilts southward and has been infilled by pyroclastics either erupted from Nabro or windblown.
Obsidian flows are located in the northern part of the caldera are the only evidence of activity following caldera collapse. The volcano contains a 100 cubic km bulk rock volume.
There is dense vegetation cover in the southern part of the caldera.
Nabro and Mallahle volcanoes erupted between 20 and 100 cubic km of ignimbrite. These two calderas may have formed at the same time.
