| Abstract: | The largest magnitude is ML3.8 small earthquake swarm which occurred on October 30, 2012, Quyuan town of Zigui County in the Three Gorges reservoir region. The studies show that the small earthquake swarm are directly related to the Three Gorges Reservoir impounding; the earthquake swarm gathered in the northern end of Xiannvshan fault zone, earthquakes most located within 10 km near the crystalline basement; linear scale of hypocenter body is smaller, mainly limited radius of 5 km of range; mainshock and larger seismic performance typical stereotype earthquake characteristics; earthquake swarm triggered the fault structure Xiannvshan stress to adjust in the high water level of the reservoir impounding, small earthquake swarm are reservoir triggered tectonic earthquakes. |
| Keywords: | small earthquake swarm reservoir triggered tectonic earthquake focal mechanism solution spectrum hypocenter body |
