• Resumen

  • In the Pleistocene lake sediments of the Acambay Basin (Central Mexican Volcanic Belt) there are 5 paleoearthquakes identified by seismites and slumps. The 4th event is correlated in the whole basin and it is possible to identify different zones of "strain intensity in the seismites". The zones have three levels related to liquefaction phenomena in silt; sand or conglomerate, with a minimum magnitude of 5 for intensity I and 7.5 for intensity III. The orientation of the intensity areas are NWSE, parallel to major active faults in the zone.
