Alid Volcano

Alid

Stratovolcano · Eritrea · 904m

The elongated Alid volcano, which sits on the axis of the Danakil spreading center, is seen here from the W. Most of the flanks of the volcano in this view are composed of dipping rhyolitic lava flows; the light-colored area along the right skyline is rhyolitic pumice. The summit of the volcano is elongated in an E-W direction and contains a 1 x 1.5 km wide, 100-m-deep crater at the western end. Vast lava fields originating from fissure vents in the Alid graben extend to the NW and SE of the volcano. Vigorous fumarolic activity continues at Alid.

Geological summary

Alid is an isolated, dissected volcano in the central Danakil depression. Elongated in an E-W direction perpendicular to the orientation of the Alid graben, it consists of a structural dome of uplifted sedimentary rocks rising 700 m above the graben floor, which was produced by intrusion of a silicic magma body. The dome is capped by steep-sided basaltic-to-rhyolitic lava flows. Late-stage eruptions during the late Pleistocene ejected rhyolitic pumice. A 2 x 3 km graben cuts the top of the dome, and the crater that produced the Plinian eruption occupies the western third of the summit depression. Vast lava fields of probable Holocene age originating from fissure vents bank up against the flanks to the NW and SE. Small cones and craters that were the source of the flows are localized along NNW-trending fissures. Fumarolic activity continues from broad areas on the northern summit and flank.

From Wikipedia

The Alid Volcano is a stratovolcano located in the Northern Red Sea region of Eritrea in the Danakil Depression. The peak elevation from its base is 904 metres (2,966 ft). The volcano's most recent activity was identified in 1928, when it emitted smoke. It is a large volcano located in the northern east coast.
