This November 2019 Planet Labs satellite image monthly mosaic shows several calderas and lava flows, with Nabro in the center and Mallahle below it, both within the Bidu Volcanic Complex of the Nabro Volcanic Range (N is at the top). The 6-km-diameter-wide Mallahle caldera contains obsidian lava flows in the northern part. Sork’Ale is partly visible to the SE.
