【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。更多还原

【Abstract】 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.更多还原
