Abstract: Based on previous research, this paper selected four seismic stations to analyze seismic capability. Through statistics of the coseismic effect of 60 earthquakes with M_S≥7 occurred in the world from 2015 to 2018 and the record of impending anomalies before large earthquakes. The results show that the body strain is good for the coseismic records of M_S≥7 earthquakes with epicenter distance of 8000 km. About 22% of the anomalies were recorded before the earthquake. At the same time, the abnormal phenomena are described and classified. This paper makes a statistical analysis of various types. In this paper, the statistical analysis of various types is carried out and the mechanical properties are preliminarily discussed.
