Large earthquakes cause intensive ground excitations and possibly results in collapse of buildings and bridges. To take into account the uncertainty in earthquake occurrence and seismic load effect in design codes, the probabilistic seismic hazard assessment approach is employed to develop the uniform hazard spectra (UHS) and seismic hazard contour maps. Although there is extensive information concerning Mexican seismic hazard assessment and code making, a detailed report on a hazard model that can be used to evaluate the UHS, to develop the seismic hazard contour maps and to assess inelastic responses is lacking. Furthermore, since the displacement ductility demand could differ for interplate and inslab earthquakes, this difference should be incorporated in estimating the reliability of structures. In the present study a workable seismic hazard model that can be use to estimate UHS and to develop seismic hazard contour maps for part of Mexico is assembled; the contribution of each individual earthquake type to the overall seismic hazard is assessed; and the seismic design load level that is required considering the differences in the ductility demand caused by interplate and inslab earthquakes is estimated.
