【摘要】 通过延怀盆地构造背景、新构造活动、古地震等资料的分析,综合构造应力场模拟、构造类比、大震离逝率、孕震蓄能等因素及由经验公式推断的研究结果,对延怀盆地设定地震相关参数进行了研究。结果表明,延怀盆地设定地震的震级上限为7,发震断层为方家冲—营门矿段断层,震源深度为10 km左右。更多还原

【Abstract】 Through analyzing the data of tectonic background,neo-tectonic movement,paleoearthquake,based on the research results by the means of tectonic stress field simulation,seismogenic structure similarity,strong earthquake elapsing rate,quake-breeding and energy-storing condition,et al.,the scenario earthquake parameters in Yanqing-Huailai Basin are preliminarily studied.The result shows that the maximum magnitude of scenario earthquake is 7,on the seismogenic fault of Fangjiachong-Yingmenkuang,and focal depth is about 10 km.更多还原
