...Morphological and seismological evidence for active slip has been documented for the following faults and faults sets (Figure 5): The sinistrally transpressive faults of the trans-Alborán shear zone (Stich et al. 2006), which form an en echelon set including the northeast- to north-trending Lorca and Palomares faults in the Betic Cordillera, the east-northeast-trending Alborán Ridge in the Alborán Sea, and the Nekkor fault in the Rif A set of linked normal and east to west dextral faults that extends from near Almerı́a on the Spanish coast westward into the Granada Basin (Martı́nez-Martı́nez et al. 2006) The east-southeast-trending dextral Yussuf fault, which cuts across the eastern part of the floor of the Alborán Sea (Watts et al. 1993) A set of east-southeast-trending dextral faults that extend from the eastern termination of the Azores Fracture Zone across the floor of the Gulf of Cádiz (the SWIM faults of Zitellini et al. 2009) The conjugate pattern of southwest-trending sinistral faults and east-southeast-trending dextral faults is consistent with northwest-directed Africa-Iberia contraction....

...Additional evidence cited in support of this hypothesis includes the accretionary wedge west of Gibraltar (see above) as well as tomographic data believed to indicate that a slab of oceanic lithosphere dips steeply eastward from Gibraltar down to the locus of the deep earthquakes beneath Granada (Gutscher et al. 2002)....
