The Groppo group contains several cones and lava flows, with a younger darker flow near the top of this December 2019 Planet Labs satellite image monthly mosaic (N is at the top; this image is approximately 42 km across). Several phreatomagmatic craters are visible, with complex groups of overlapping vents and at least one possible maar. Several of the scoria cones have craters that experienced flank collapse or rafting during their eruptions, including the northernmost cone.

Resumen geológico

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.
