Scientists find Earth’s mantle beating like a heart, slowly tearing Africa apart
- Scientists have discovered a deep, rhythmic pulse under Africa, suggesting the continent is being torn apart in the formation of a new ocean basin.
- The mantle beneath Afar is not uniform or stationary; it pulses like a heartbeat, carrying distinct chemical signatures.
- The rhythmic pulsing indicates active geological processes that imply significant geological activity.
- These findings have profound implications for understanding volcanism, earthquakes, and continental breakups.

Mantle upwelling at Afar triple junction shaped by overriding plate dynamics
Mantle upwellings drive large-scale surface volcanism and facilitate continental breakup and ocean basin formation. However, the spatial characteristics and internal composition of these upwellings alongside how they are modified by plate tectonics are poorly resolved. Afar, East Africa, is a classic triple junction comprising three rifts at various stages of evolution thought to be underlain by a mantle upwelling or plume, allowing examination …
