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.
