- Abstract:
- During Sep. 22 to Oct. 18, 2007, a microquake swarm occurred in Luoquanhuang, Zigui, Hubei(the maximum magnitude is ML2.9 on Oct. 7). The macroscopic epicenters distribute along Huangnitan, the meizoseismal area is small and the seismic wave attenuates fast, which reflects the sources are shallow. We compared the seismic waveform, spectrum characteristics and corner frequency of the Luoquanhuang microquake swarm with those of the natural earthquakes and reservoir-induced earthquakes around the area, and found that they are different obviously. Synthesizing the macro-investigation and seismological analysis, we think the swarm should be in mining-earthquake.
