Since 2005, a 35-mile fissure has been forming at this geologic region’s Dabbahu Volcano. A major lava lake lies in this region’s volcano Erta Ale. A formation denoted “RRR” in this region created its Gulfs of Zula and Tadjoura. This region’s Awash River yielded the Hadar jaw—arguably the oldest Homo specimen—and the namesake of Ardipithecus, whose name derives from a language sharing this region’s name. It’s not Iceland, but a terrestrial mid-ocean ridge in this region exemplifies (*) ocean formation. This region’s Lake Assal is Africa’s lowest point.
