Description :
Broadly curved distorsions are stressed by the upheaval of both shores of the Straight of Gibraltar together with that of two areas on each side of the Alboran Sea: the Campo de Dalias, West of Almeria in Spain and the Beni Saïd, Westoff Melilla in Morocco. Both areas are separated from the Straight of Gibraltar by subsiding littoral zones. Some weak, highly localized deformations due to a fault tectonics are perceptible on the Eastern Betic Cordillera coast. West and East of Almeria. The broadly curved distorsions are the result of movements inherited from the neogen history of the district and progressive during Quaternary| The upheaval rate in the Straight of Gibraltar is about 0.015cm a year for the last 100000years. The breaking strains seem to be linked to the great transverse faults posterior to the last alpine phases which have therefore worked at least up to ancient Tyrrhenian.
