Bora-Bericcio (Ethiopia)

Status Normal Eruption Unknown 2267m
Pyroclastic cone(s) (Rift zone / Continental crust (> 25 km))

The silicic Bora and Bericcio pumice cones are among the most youthful volcanoes of the Ethiopian Rift valley. Bora has a 1.5-km-wide summit crater; the more conical Bericcio is capped by a small summit crater and has a 1-km-wide crater on its S flank. Small silicic pyroclastic cones are found on the E flanks of both. All volcanic products in this area are considered to be Holocene, and there is ongoing vigorous fumarolic activity.

Mount Bericcio, a rhyolitic pumice cone along the Wonji Fault Belt in Ethiopia, is part of the Bora-Bericcio volcanic complex. Produced by the accumulation of rhyolitic pumice around its vent, Bericcio is capped by a small summit crater. Erosion of the unconsolidated pumice has produced parasol-like ribbing on the flanks of the cone. Its twin volcano, Bora, has a 1.5-km-wide summit crater. Small silicic pyroclastic cones are found on the east flanks of both Bora and Bericcio. Vigorous fumarolic activity continues.
