-80 m a.s.l. We have reached the flat bootom of the Danakil depression. A large, fresh-looking lava flow covers much of the area here. The extension and sinking of the earth's crust creates fractures through wich basalt is frequently erupted. Despite such eruptions and the deposition of sediments, the land is sinking. It's only a matter of (geologically) short time, before this land will be invaded by the sea and become ocean floor. (Photo: Tom Pfeiffer)
