a General location map, tectonic setting and primary faults of the S. Iberian/N. Moroccan region (Simplified from Gutscher et al. 2006 and Omira et al. 2009). Major earthquakes (Mb 6.5) are shown with date. Dashed line represents likely position of plate boundary separating Iberia (Eurasia) from Africa (Nubia) and defining a third, pie-shaped block (the Rif–Betic–Alboran domain). Potential tsunamigenic source zones and the corresponding typical faults are represented; GBF = Gorringe Bank Fault, HSF = Horseshoe Fault, MPF = Marques de Pombal Fault, PBF = Portimao Bank Fault as well as CWF = Cadiz Wedge fault. The subduction fault plane (below the accretionary wedge) has been proposed as being the potential source of the 1755 M 8.5 Great “Lisbon” earthquake. b Isoseismal map (of the 1755 earthquake shows entire felt zone in NW Africa, Western Europe and the NE Atlantic
