摘　　要：震后趋势判定是灾区社会大众非常关注的一个热点。通过分析云南省2008—2018年期间,5级以上双震数字化定点形变的同震阶变幅度大小与后续地震发生的相关性。认为双震发生后,定点形变的同震阶变幅度与未来是否会出现更大地震直接相关。The determination of the subsequent-earthquake trend is a hot topic for people in the disaster area.By analyzing the correlation between amplitudes of co-seismic deformation and subsequent earthquake from double earthquakes during 2008—2018 recorded by digital fixed point deformation instruments,it can be considered that two amplitudes of the co-seismic steps of fixed point deformation is directly related to the possibility of larger earthquake’s occurrence after double earthquakes in Yunnan.
