Geometría, cinemática y paleosismicidad de las zonas de falla de Baza y Galera

Résumé

The study of active faults consists of a detailed characterisation of these structures to analyse and understand their behaviour within seismic regions and thus develop neotectonic deformation models. Moreover, knowing the fault geometry and kinematics is one of the first steps in the seismological and palaeoseismological characterisation of active faults. The Central Betic Cordillera is one of the most active tectonic zones on the Iberian Peninsula and is associated with the highest seismic hazard. This PhD thesis is focused on the characterisation of the Baza Fault (BF) and the Galera Fault (GF), the main active faults of the Baza Subbasin, located in the eastern sector of the Guadix-Baza Basin (Central Betic Cordillera, S Spain). This research integrates different approaches, including structural geology, tectonic geomorphology, palaeoseismology, tectonic geodesy, and seismology. Moreover, we discuss the influence of these faults on the recent relief of the basin during the exorheic stage (ca. 500-600 ka) and propose a local neotectonic model for the Baza Subbasin, integrating both faults in the geodynamic setting of the Central Betic Cordillera.
