One mode is slippage along the discontinuity provided by the lubricated fault plane. 其中一种方式是沿着润滑的断层面所形成的间断面而发生滑动。
According to focal mechanism,the directions of main press stress of the two are NNW in the seismic area but the fault plane solutions are different. 震区的主压应力为北北西方向，两震的受力方向基本一致，但断层面解明显不同。
