Erta Ale

Gunung api perisai · Ethiopia · 585 m

The summit of Erta Ale contains a 0.7 x 1.6 km elliptical caldera containing pit craters. A plume rises from the N pit at the left, and a lava lake was active in the center pit crater at the time of this February 2002 view from the S. It is an isolated basaltic shield volcano that is the most active volcano in Ethiopia. Recent basaltic lava flows fill much of the caldera and have overflowed its rim on the southern side. One, or sometimes two, long-term lava lakes have been active since at least 1967.

Ringkasan geologi

The Erta Ale basaltic shield volcano in Ethiopia has a 50-km-wide edifice that rises more than 600 m from below sea level in the Danakil depression. The volcano includes a 0.7 x 1.6 km summit crater hosting steep-sided pit craters. Another larger 1.8 x 3.1 km wide depression elongated parallel to the trend of the Erta Ale range is located SE of the summit and is bounded by curvilinear fault scarps on the SE side. Basaltic lava flows from these fissures have poured into the caldera and locally overflowed its rim. The summit caldera usually also holds at least one long-term lava lake that has been active since at least 1967, and possibly since 1906. Recent fissure eruptions have occurred on the N flank.
