Short summary

The Ibero-Maghrebian region has experienced major natural disasters affecting the coasts of the southern Iberian Peninsula and North Africa. This study presents a seismic hazard assessment using deterministic and probabilistic approaches across the marine strip between west Gulf of Cádiz and east Alboran Sea. The expected peak ground accelerations (PGA) exceed 1 g in certain submarine areas, indicating a high potential for earthquakes in the region and poses a risk to subsea infrastructures.
