Nabro Volcano

Nabro

Stratovolcano · Eritrea · 2218m

The large caldera below and to the left of the center of this Space Shuttle photo of the Danakil Alps of Ethiopia is Nabro. This volcano is the highest in the Danakil depression and is truncated by nested calderas 10 and 5 km in diameter. The larger caldera is breached to the SW. The 8-km-wide Mallahle caldera is at the lower left, and the dark-colored lava flows at the right are from Dubbi volcano.

Geological summary

The Nabro stratovolcano is the highest volcano in the Danakil depression of northern Ethiopia and Eritrea, at the SE end of the Danakil Alps. Nabro, along with Mallahle, Asavyo, and Sork Ale volcanoes, collectively comprise the Bidu volcanic complex SW of Dubbi volcano. This complex stratovolcano constructed primarily of trachytic lava flows and pyroclastics, is truncated by nested calderas 8 and 5 km in diameter. The larger caldera is widely breached to the SW. Rhyolitic obsidian domes and basaltic lava flows were erupted inside the caldera and on its flanks. Some very recent lava flows were erupted from NNW-trending fissures transverse to the trend of the volcanic range.

From Wikipedia

The Nabro Volcano is an active stratovolcano in the Southern Red Sea Region of Eritrea. It is located at the south-east end of the Danakil Alps in the Danakil Depression. Before its 2011 eruption, the volcano was widely believed to be extinct.
