This database synthesizes information on the geometry, the sense of movement and the last displacement on known Quaternary faults in Mexico. Faults are classified according to the age of the last known geologic displacement and the quantity and quality of the information available. Class A faults have documented displacement in the Holocene; Class B faults have Pleistocene displacement with possible reactivation in the Holocene; and Class C faults have a last known displacement in the Pleistocene.

The availability of a complete Quaternary fault database would be of great benefit in the calculation of the probabilistic seismic hazard. These surface-faulting sources have generally been excluded in the preparation of national seismic-hazard maps in Mexico, despite their obvious effect on the hazard expected for inland areas characterized by seismogenic structures capable of producing large earthquakes. The exclusion has been due primarily to a scarcity of complete and reliable active-fault information. The GIS format of the current database, however, is expected to allow a timely update of fault information as more data become available.
