Abstract

The Changning M6.0 earthquake in Yibin, Sichuan on June 17, 2019, caused heavy casualties and property losses. The highest intensity of the earthquake was Ⅷ. In this paper, the damage characteristics and intensity distribution of Changning earthquake are emphatically analyzed, and the spatial distribution characteristics of ground motion are analyzed in detail. The results show that the E-W component PGA and N-S component of the peak acceleration of the Changning earthquake are quite different in the horizontal ground motion. The strength of the E-W component is greater than that of the N-S component in the whole. The main building structures in the disaster area are frame structure, brick-concrete structure and brick-wood structure. Frame structure and brick-concrete structure are the main building structures in disaster areas. They have seismic fortification measures and good seismic performance. However, most of the self-built brick-concrete buildings in rural areas do not have seismic fortification, and their seismic capacity is poor.
