Groppo Volcano — Ethiopia

Groppo was identified by IAVCEI (1973) as a small alkali rhyolitic stratovolcano located in the western Afar near the Ethiopian escarpment, NE of Dessye. However, the nearest volcanic feature, identified in satellite imagery about 15 km NW from the given location, is a dark lava-flow field about 2.5 x 4.5 km in size, surrounding two small cones; two other smaller breached cones are nearby. The largest cone is about 300 x 500 m long, and 45 m high.
