摘 要
The present disclosure provides an earthquake evaluationmethod based on multi-type geophysical data.The methodincludes: acquiring natural seismic data about intraplateearthquakes that had occurred, surface elevation data, Bou-guer gravity anomaly data,aeromagnetic anomaly data,seismic wave tomography, crustal GPS movement rate andfocal mechanism solution in a target region; constructingplanar grids of the target region, and respectively performingplane gridding processing on the natural seismic data aboutthe intraplate earthquakes that had occurred, the surfaceelevation data, the Bouguer gravity anomaly data,and theaeromagnetic anomaly data based on the constructed planargrids of the target region; determining a plane distributionmap of a meizoseismal area in the target region based on thedata subjected to the plane gridding processing; and super-imposing a surface elevation map and the plane distributionmap of the meizoseismal area in the target region with theseismic wave tomography,and analyzing the crustal move-ment on both sides of the meizoseismal area and the match-ing relationship between the meizoseismal area and thecrustal geological structure in combination with the crustalGPS movement rate and the focal mechanism solution so asto determine the geologic origin of a pleistoseismic zone.
