Seismogenic considerations on the vertical slip rate of the frontal strands of the carrascoy fault (se iberian peninsula) from p-wave tomography analysis

[EN]: A seismic profile has been performed across the Algezares-Casas Nuevas fault zone, the SW section of the major Carrascoy Fault, a potential source of earthquakes in the region and hence an important threat to the nearby City of Murcia. The seismic data were processed to obtain a Vp model and p...

The seismic data were processed to obtain a Vp model and provide insight into the depth structure of the fault zone. The Vp model was interpreted according to the local geology and surface data, enabling the location of the Messinian/Tortonian contact, and also the erosive contact of the Red Unit (Pliocene alluvial fan deposits) on the Messinian deposits. Both contacts are offset by two principal thrusts identified in the profile, by a similar amount ca. 135-140 m. Considering the age of the onset of the deformation, quoted in 209 ka in previous studies, a vertical slip rate around double that previously calculated can be estimated. We discuss the different causes for this disagreement and we conclude about the important impact that such a slip rate could have on seismic hazard studies.This research was funded by the Secretaría de Estado de Investigación, Desarrollo e Investigación (MINECO) projects INTERGEO (CGL2013-47412-C2-1-P) and QUAKESTEP (CGL2017-83931-C3-1-P).
