Tectonic map of the Al Hoceima region (compiled from Calvert et al., 1997; Ait Ibrahim, Tadili, et al., 2004) with surface cracks and fissures observed after the 2004 event (redrawn from Ait Brahim, Nakhcha, et al., 2004). Red circles are the M >4 aftershocks of the 2004 event whose epicenter is shown with a star (from IGN). Thick white line is the surface trace of the modeled fault plane.
