- Abstract:
-
On the basis of digital seismograms recorded at 11 stations of Xiaowan Reservoir Induced Earthquake Monitoring Network from 21 May,2005 to September 2006,we inverted source parameters near Xiaowan reservoir using genetic algorithm by the help of the known non-elasticity attenuation and site response and got source parameters such as seismic moment,stress drop and corner frequency of 328 earthquakes.We discussed the relation of source parameters in Xiaowan reservoir and its vicinity.The study shows that the stress level in Xiaowan reservoir region is clearly lower than that in the region near Xiaowan reservoir.
