Application of Earthquake-Pair Mapping Methods to Estimation of Strong Ground Motion Parameters

Because of abundant earthquake motion records in Western America and isoseismal data in south Central China,we take south Central China as study area and Western America as referred area,use the earthquake-pair mapping methods(IM-and IR-mappings) to estimate various factors effecting the attenuations of peak ground acceleration and response spectral frequency parameters on rock sites in the study area.
