INTENSITY ASSESSMENT AND SEISMIC DAMAGE CHARACTERISTICS ANALYSIS OF WUSHI MS7.1 EARTHQUAKE
After Wushi MS7.1 earthquake occurred on January 23,2024,the seismic intensity map was drawn according to the post-earthquake damage survey results,combined with the remote sens-ing image,focal mechanism and seismogenic structure of the earthquake area.In the process of drawing the intensity map,the Ⅸ degree is located in the mountainous area and lacks the layout of the strong earthquake network.Therefore,the InSAR results are referred to for the first time when determining the Ⅸ degree intensity circle.By comparing the results of earthquake damage investiga-tion and instrument intensity results,it is found that the two are in good agreement,so the instru-ment results are referred to when determining the boundary of the intensity circle.This study focuses on the destruction of various types of houses in different intensity areas and the phenomenon of earth-quake geological disasters,and analyzes and determines the characteristics of various types of house damage.
