Abstract：We undertake dense observation of Fuling Jiaoshi area, Chongqing, for a period of 1 a by setting up mobile stations to understand the characteristics of seismicity in this area. We explore the genetic mechanism of microseisms and the reasons of significant differences in seismicity between others shale gas reservoirs in Sichuan basin. The results show obvious microseisms in this area. The relocated microseisms are mainly distributed in clusters along multiple faults on the boundary of the exploitation area and are concentrated near the peripheral faults on the southeast side of the exploitation area. The dominant focal depth of earthquakes is 2—6 km. We infer that the seismic activity in this area may be related to the localized disturbance on the boundary fault caused by industrial activities and the seismic disaster risk in this area is relatively small due to the direction of stress field, stress magnitude and tectonic characteristics.
