摘要：

We mapped Plio-Pleistocene lake deposits in the Ixtlahuaca paleobasin in Central Mexico, located 51 km south of the Acambay Graben and 69 km west of Mexico City. Within the Acambay basin, Pleistocene to Holocene lake sediments record primary and secondary environmental effects of strong local earthquakes as a consequence of Quaternary activity of the major normal border faults. Likewise, the Ixtlahuaca paleobasin has been controlled mainly by the Quaternary evolution of the Perales and Ixtlahuaca faults, even if there is no record of local historical earthquakes, and therefore the area has not been considered as potentially seismic. However, the application of the ESI 2007 Scale to deformation structures as effects of seismic events on the geological-natural environment in the Tierras Blancas - San Bartolo Lanzados basins and San Pedro El Alto, within the Acambay graben, and its comparison with seismites identified in the Ixtlahuaca paleobasin, show that past earthquakes similar to the Mw 6.5 to 7 surface faulting events generated by the main faults of the Acambay graben have also occurred in the Ixtlahuaca area.
