Tectonic Structure of Morocco
Guide du Maroc
Rif Range
Active subduction zone in the north, responsible for Al Hoceima earthquakes. Shallow faults with high activity.
High Atlas
Range in continuous uplift, deep earthquakes but potentially destructive like the 2023 event.
Anti-Atlas
Ancient and stable structure, limited seismic activity.
