This method has been applied to the Al Hoceima Bay (southwesternmost Mediterranean, Alboran Sea) for a time period covering the last 280 kyr on 672 faults imaged on 265 high-resolution seismic reflection profiles. This area was affected by major earthquakes and corresponds to a transtensional basin deformed by growth faults. The automated application of throw backstripping allowed for a faster deciphering of the migration of tectonic activity. Results show a westward migration of the deformation with quickly increasing deformation rates in the most recent time frames near Al Hoceima, one of the most populated cities. This migration is in agreement with the current seismicity, the GPS data, and recent brittle deformation data. Vertical throw rates of up to 0.47 mm/year have been calculated, for the most recent time periods, in segments of the Bokkoya fault zone. The westward migration of the deformation fits with the reconstruction suggested by the westernmost Mediterranean geodynamic models during the Pleistocene epoch, and it might be the consequence of the interaction between the northwest (NW) movement of the South Alboran indenter and the back Rif south-westward displacement. The highly accurate constraints of the evolution of the tectonic activity offered by this automation will substantially improve the seismic hazard assessment This study was supported by projects CGL2016-80687-R AEI/FEDER, P18-RT-3275, B-RNM-301-UGR18 and RNM148 (Junta de Andalucía/FEDER); ALBAMAR JCJC ANR-17-CE03-0004; the EUROFLEETS program (FP7/2007-2013; n°228344); project FICTS-2011-03-01; and the FPU PhD grant (16/04038), and also by the Spanish Government through the ‘Severo Ochoa Centre of Excellence’ accreditation (CEX2019-000928-S) Peer reviewed 2021-04-14T06:16:24Z 2021-04-14T06:16:24Z 2021-04 artículo http://purl.org/coar/resource_type/c_6501 Frontiers in Earth Science 9: 645942 (2021) CEX2019-000928-S http://hdl.handle.net/10261/237909 10.3389/feart.2021.645942 2296-6463 http://dx.doi.org/10.13039/501100003329 http://dx.doi.org/10.13039/501100011033 http://dx.doi.org/10.13039/501100000780 en #PLACEHOLDER_PARENT_METADATA_VALUE# #PLACEHOLDER_PARENT_METADATA_VALUE# info:eu-repo/grantAgreement/MINECO/Plan Estatal de Investigación Científica y Técnica y de Innovación 2013-2016/CGL2016-80687-R info:eu-repo/grantAgreement/EC/FP7/228344 https://doi.org/10.3389/feart.2021.645942 Sí open Frontiers Media
