“…However, along the western margin of the Baja California peninsula (Fig. 1), some active faults, such as the Tosco-Abreojos fault system in the southern part of the Baja California margin, still accommodate a small part of the motion (DEMETS, 1995;DEMETS and DIXON, 1999;DIXON et al, 2000;FLETCHER and MUNGUIA, 2000;MICHAUD et al, 2004;MICHAUD et al, 2005MICHAUD et al, , 2007. The relative displacement between the Pacific plate and Baja California Sur is consistent with a right lateral motion along the margin and with the focal mechanisms of earthquakes occurring in this region (Fig.…”

“…The formation of the GoC extensional province occurred in two phases: in the first stage the extension and continental separation formed continental marine basins, whereas during the second phase, a period of seafloor expansion and creation of transform faults took place, and these latter processes continue today (Stock and Hodges, 1989;Oskin et al, 2001;Bennett et al, 2007). As a consequence, the crustal structure at the margins of GoC is different with respect to the crustal structure along the plate boundary within the GoC (Fletcher and Munguía, 2000). The estimates of Q for S waves (Figs.…”

“…En su porción oeste, la cuenca está limitada por la falla normal San José del Cabo (FSJC), la cual se inclina hacia el este. Fletcher et al (2000) registraron una exhumación acelerada del basamento de 12-10 ma., la cual relacionaron con la activación de la FSJC. Dicha falla presenta periodos de reactivación durante el Cuaternario, evidenciados geomorfológicamente por la presencia de escarpes de falla y terrazas aluviales en valles fluviales en el bloque de piso (Gaitán-Morán, 1985).…”

“…Fletcher et al (2000) determinaron el inicio de la exhumación acelerada en el bloque de piso hace 12 -10 ma., marcando el inicio del fallamiento en la cuenca, el cual estos autores relacionaron con la activación de la FSJC. Recientemente Busch et al (2011) reconocieron varias fallas sepultadas a lo ancho de la cuenca y especularon que específicamente una falla por debajo de la localidad de Santiago (Figuras 1 y 2), la cual llamaron falla Santiago, pudo haberse formado antes de la FSJC.…”
