The crust under Africa is thinning in a way that hasn’t been seen before

The continent won’t split anytime soon. But the thinning is a critical transition

An image of he Turkana Rift Zone in Africa, where Earth’s crust is pulling apart. The landscape is mostly brown and barren.

The Turkana Rift Zone (shown) in Kenya and Ethiopia is on a critical transition to continental breakup.

It’s a bit of a stretch, but the analogy works. Sometimes Earth’s tectonic plates pull apart from one another like taffy.

In eastern Africa, that taffy is already thin and weak, and the tugging forces are concentrated in certain spots.
