| Abstract: | In this paper, based on the ML ≥ 2. 0 earthquakes which were recorded by the seismic observation network of Fujian province from 2009 to 2012, and according to the condition of the fracture characteristics and the space distribution of the earthquakes, the research area is divided into three parts. The distribution of the wave velocity ratio and Poisson＇ s ratio in Fujian is studied by the multi-station Wadati method, and dis- cussed the varied characteristics of the wave velocity ratio in Xianyou ML4. 1 earthquake. |
