“…This collision was associated with magmatic activity (generally related to transpression of strike-slip faults; Bordet, 1985;Hernandez & Bellon, 1985;Torres-Roldán et al, 1986; Di Battistini et al, 1987;Hernandez et al, 1987; Chotin & Aït Brahim, 1988; Aït Brahim & Chotin, 1990;El Bakkali et al, 1998; Zeck et al, 2000;Fernández-Soler, 2001) in a large area still characterised by scattered, low-magnitude earthquakes (concentrated at pre-existing structural weakness zones and most frequently focused at shallow to intermediate depths; Buforn et al, 1988Buforn et al, , 1995Morales et al, 1997). These varied phenomena are all responses to geodynamic processes controlled by the Africa-Europe convergence (Argus et al, 1989;Morales et al, 1999; Calvert et al, 2000;Gutscher et al, 2002).Plate-tectonic wise, Iberia was an independent microplate separate from Europe and Africa from the late Middle Eocene until the beginning of the Miocene (Srivastava et al, 1990;Roest & Srivastava, 1991). In the earliest Miocene, its northern plate boundary became extinct and, as a consequence, the Iberian microplate became part of Europe.…”
