摘要
By using the results of accurate location and the focal mechanism solution of Shunchang ML4.9 earthquake sequences recorded by Fujian digital seismic network, this paper investigated the local seismotectonic environment, seismic activity and seismic intensity. The results show that the Shunchang earthquake is a “double main earthquakes type” swarm activity. The fracture direction of main earthquake is NE direction and its occurrence mechanism is NE-directional slip fracture with the effect of the NW directional main compressive stress.
