A magnitude 6.8 earthquake struck western Morocco in September 2023, causing significant damage and casualties. Researchers have found that the quake originated from a deep fault plane within the Tizi n’Test fault system, suggesting a connection to mantle upwelling rather than surface faulting. This highlights the importance of considering deeper dynamics in intraplate regions for seismic hazard models and emphasizes the need for increased monitoring in areas with infrequent but devastating earthquakes.
