摘要
收集2008—2015年辽宁境内M_L≥3.0地震波形资料,读取P波初动,采用P波初动方法,求解地震震源机制解。分析盖州震群、海城序列等地震的震源机制不同变化特征。
We collected seismic waveform of earthquakes（ML ≥ 3.0） in Liaoning from 2008 to 2015, and read out initial P wave polarity from the wave. Then we calculated the focal mechanism solutions of the earthquakes using P-wave first motion method and analyzed different variation characteristics of the solutions of Gaizhou earthquake swarm and Haicheng earthquake sequence.
