| Abstract: | The Gibraltar Arc (Western Mediterranean Sea) is traversed by a NE-trending fault system that extends from northern Morocco to southeastern Spain. In this area, three main faults (the Carboneras, Palomares and Alhama de Murcia faults) have been active in Quaternary time. The faults are characterized by left-lateral strike-slip motion. The Quaternary faulting and current seismicity in this part of the Meditterranean area are related to a collision-type tectonics produced by the northwestward relative motion of the African Plate toward the European Plate. |
