Overview

Ayelu is a vegetated rhyolitic stratovolcano, located south of the Asbahri plain in the southern Afar region. On its eastern side, 2145-m-high Ayelu is cut by regional faults and is overlain by ignimbrites erupted from Adwa volcano immediately to the east. It was constructed by a series of thick rhyolitic lava flows, creating a higher and steeper-sided volcano than Adwa.

Hot springs are located on the western flank.

Regional Volcanic Activity
The Eastern Africa Volcanic Regions contains multiple active volcanic systems. Cross-regional magma interactions and tectonic stresses can influence eruption patterns across the entire arc. Monitor regional seismic activity and volcanic alerts.

About the Photo

Ayelu is the westernmost and older of two volcanoes at the southern end of the Danakil depression. The vegetated volcano is cut by prominent regional faults. Hot springs occur on its W flank. Extensive young basaltic lava flows cover the flanks of Adwa volcano and overlap a sedimentary plain to the SE.
