Erta Ale—Compact Fury of Lava Lakes

Taught by Professor Michael E. Wysession | 26 min | Categories: The Great Courses Plus Online Science Course

Zoom in on a remarkable feature of the African Rift Valley: the lava lake at Erta Ale in Ethiopia. This seething cauldron of molten rock is the oldest of the world’s five active lava lakes, and it replicates on a small scale the complex process of plate tectonics.
