Resumo

The recent geodynamic activity in the Betic-Rif Cordillera and the Alboran Sea is determined by the interaction of subduc- tion processes with roll-back in the West and tectonic indentation in the East. The integration of sea and land data in the DAMAGE project characterizes the central area of interaction. At the northern end, the seismicity of the frontal region of Sierra de Cazorla is associated with incipient tectonic indentation. To the South, seismic and aseismic extensional faults of high and low angle interact in the Granada Basin. The active normal faults in the Campo de Dalías are connected with recent and new strike-slip faults that affect the Alboran Sea, being responsible of the 2016 Alhoceima earthquake (M 6.3). Towards the Rif, new areas of deformation in the Al Hoceima region are identified on blind faults with significant seismogenic activity in 1993 and 2004. These structures represent an important geological hazard related to slope instability and tsunami development in the Alboran Sea and in water reservoirs. The economic and social impact of this geological hazard should be considered and quantified.
