【Abstract】 There exists a ground rupture zone along north section of the Shunyi Liangxiang fault zone near Beijing. We have made field investigation, chemical exploration and trough exploration to study its cause. It is suggested that this rupture zone reflects recent activity of north section of the Shunyi Liangxiang fault. Seismicity along this fault section as well as potential hazards caused by it should be taken into consideration for construction planning.更多还原
