Boset-Bericha

Boset

Stratovolcano · Ethiopia · 2447m

The Gudda and Bericha edifices comprise the Boset volcanic complex, one of the largest volcanoes within the northern Main Ethiopia Rift at 17 x 20 km in extent. The main edifices are in the lower left quarter of this November 2019 Planet Labs satellite image monthly mosaic with darker, younger lava flows on the flanks and to the NE at Kone (N is at the top; this image is approximately 39 km across). The Boset-Gudda) cone forms the SW potion, and the Boset-Bericha cone is NE.

Geological summary

The Boset volcanic complex includes the Boset-Gudda (Great Boset) and Boset-Bericha (Little Boset) composite volcanoes rising above the floor of the Ethiopian Rift valley. Initial basaltic-to-trachytic activity at Gudda followed by rhyolitic effusive and explosive eruptions resulted in the formation of a caldera, a remnant of whose rim is found on the NW flank. Elsewhere, post-caldera activity produced very recent pantelleritic obsidian fissure-fed lava domes and flows that buried the caldera wall. Flank eruptions from fissures parallel to the rift produced voluminous pantelleritic lava flows. Bericha has produced similar very recent obsidian flows and associated pumice flows. Fissures connecting the edifices have erupted basaltic lava flows.
