No latest activity reported for Corbetti Caldera.

Below is a summary of eruption dates and Volcanic Explosivity Indices (VEI).

The following references are the sources used for data regarding this volcano. References are linked directly to our volcano data file. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title. Additional discussion of data sources can be found under Volcano Data Criteria.

The 15-km-wide Corbetti caldera overlaps the NW margin of the older 30 x 40 km Awasa caldera. Urji volcano was subsequently constructed in the center of Corbetti caldera, which also contains young lava flows. Chabbi volcano, a large obsidian dome that grew on the SE caldera rim, has erupted lava flows onto the caldera floor. The age of the latest eruptive activity at Corbetti caldera is not known, although many lava flows are too young to date by the Potassium-Argon method. Fumarolic activity continues at the post-caldera cones of Urji, Chabbi, and an unnamed pyroclastic cone on the west rim.
