| Abstract: | An earthquake with magnitude of M_S5.3 occurred on Sep.12,2018 in the border area between Ningqiang County,Shanxi Province and Guangyuan City, Sichuan Province. The on-site investigation shows that the maximum intensity of this earthquake event reaches Ⅵ degree. The isoseismal is generally in elliptic shape with long axis trending near NE direction. The area of Ⅵ degree includes the 13 towns of the Shanxi and Sichuan Provinces. A part of buildings in the area were Slightly damaged by this earthquake. The Qingchuan fault of the Longmenshan fault zone is the seismogenic structure for this earthquake event. |
