摘要
Using P-wave’s travel time, the authors implemented a simultaneous inversion of the earthquake relocation and velocity structure, and got the new location of the ML4.6 earthquake in Shanxi-Reservoir area. Assuming the seismogenic fault can be fitted with a plane, the authors fitted the fault parameters with the new source parameters of the Shanxi-reservoir earthquake. The authors collected P-wave’s first-motion data of 313 earthquakes to calculate the focal-mechanism solutions of the ML4.0 earthquakes. Finally, the authors discussed the seismogenic structure of the Shanxi Reservoir area. The ML≥4.0 focal mechanism solutions of the nodal plane, strike, dip, P-axis azimuth and elevation were generally in good agreement.
