Summary

Story summary

Africa is slowly splitting along the East African Rift as the Nubian and Somalian plates separate at about 0.28 inches per year.
This long-term process is driven by geological activity in the Afar region, where three tectonic rifts converge.
Recent studies show the mantle beneath Afar is dynamic, with pulses of molten rock influencing the rifting.
The findings highlight potential seismic and volcanic risks for nearby populations.
