摘 要: 根据龙门山构造带的地震地质特征、地震活动规律及新构造活动特征,认为该地区区域稳定性受控于龙门山断裂带,而断裂带又以韧性切变形为主,蠕滑运动为特征,这决定了该带在相当长一段时间内,发生强烈地震的可能性不大。 On the basis of seismic geological characteristics,seismic activity regularities and neotectonic movement,this paper suggests that stability of the Longmenshan structural belt is controlled by the Longmenshan fracture zone.The fracture zone is characterized by ductile shear deformation and creep slippage.So,it is impossible of a strong earthquake in this area within a long time.
