A Quaternary overthrust is described, intersecting a sedimentary breccia covering the +5 m terrace of the Ibor River, at the western end of the Montes de Toledo. The resulting thrusting system has conditioned the location of fini-neogene alluvial fans ("raña"), so it has to be considered as active during the last 9 Ma. The associated, superficial earthquake is estimated to range between M 6-6.5 in magnitude. The rupture is located less than 20 km from the Almaraz Nuclear Power Plant (Cáceres).
