The Awash River in the Afar Triangle.
Looks like a major site for a geological disaster, as the sea floods in from Djibuti into the Afar depression, which is below sea level.
Because it’s a triple plate junction on a rift valley, the possibility of catastrophic flooding exists.
The Awash would then live up to its name.
Given enough time, the whole region is expected to split open creating another Red Sea. But i’d be more worried about the rift filling up with lava in another flood basalt event.
This chasm opened up in the region in just a few days in 2005.
