摘要
利用P波初动求解中俄交界4.8级地震的综合震源机制,通过震源机制反演震源区附近的应力场,结果表明:此次地震是略带走滑分量的正断层。主压应力场的方向是北北东方向,沿此断裂带展布。
We used P wave onset calculate comprehensive focal mechanism of M 4. 8 earthquake in China-Russian boundary. We inversed the stress field near hypocenter by focal mechanism. The results shows：the earthquake is on a normal fault with strike-slip component, the principal compression stress field is in NNE direction, distributs along this fault zone.
