Revision of the paleoseismic data at Los Trances and El Hacho sites, on the northwestern edge of La Serrata range, provides the first evidence of this fault being seismogenic. The fault has undergone a minimum of 5 paleoearthquakes since 133-56.6 ka which can be observed in the geological record at both sites (only the youngest is uniquely detected at El Hacho). This is a minimum amount of earthquakes given the non-continuous sedimentation sequence recorded in the area. A maximum recurrence period of 26-11 ka is obtained since 133-56.6 ka. However, when only the last 3 events are considered, the recurrence lowers down (13-9 ka) suggesting: or 1) clustering in the most recent period, or, again, 2) incompleteness of the seismic history owing to a discontinuous geological record. The 3D analysis at El Hacho provides also evidence for the lateral slip per event, which might be of 1.5m, corresponding to a Mw 6.9-7 earthquake Peer Reviewed 2018-10-30T13:05:37Z 2018-10-30T13:05:37Z 2018-06 2018-10-30T13:05:37Z comunicación de congreso http://purl.org/coar/resource_type/c_5794 isbn: 978-84-09-02473-5 Iberfault 2018 : Avances en el estudio de Fallas Activas, Terremotos y Peligrosidad Sísmica de Iberia : III Reunión Ibérica sobre Fallas Activas y Paleosismología : Volumen de resúmenes: 83-86 (2018) http://hdl.handle.net/10261/171746 http://home.iberfault.org/ Sí open |
