Collecting and processing the observed strong ground motion records of the earthquake sequence, using the observed strong ground motion records and the rapid intensity reporting station records, analyzing the time–frequency characteristics of strong ground motion, and combining with observed records thus to provide the ground motion influence field; developing earthquake damage survey of engineering structures, estimating the damage grade and characteristics of engineering structures, conducting aftershock monitoring for typical engineering structures, and investigating casualty factors through site survey to provide more data for the improvement research of the seismic performance of buildings and the rapid estimation of earthquake damage.
