Dofen

Vulcano a scudo · Ethiopia · 1151 m

Lava flows form the southern flank of the Dofan volcanic massif, NW of a bend in the Hauash River, in the center of this December 2019 Planet Labs satellite image monthly mosaic (N is at the top, this image is approximately 20 km across). An undated darker lava flow above the center of this image erupted from a vent on the N flank. · Foto: Satellite image courtesy of Planet Labs Inc., 2019 (https://www.planet.com/).

Sintesi geologica

The Dofen shield volcano rises 450 m above the Awash plain in the northern Main Ethiopian Rift. Numerous cinder cones, constructed along a 10-km-long, N-S-trending line, occur on the flanks of the dominantly rhyolitic volcano. The northern cones are younger, have well-preserved morphologies, and display strong fumarolic activity. A major fumarole in a wide S-flank crater has precipitated large amounts of sulfur. The latest eruptions occurred during the Holocene (WoldeGabriel 1987, pers. comm.), and it is known as the "smoking mountain".
