引言云南省地质构造运动复杂、剧烈,地震活动频度高,强度大,是一个多地震的地区。从1957年昆明地震台建成开始,到1965年云南的地震工作有了很大发展,建立了中国科学院昆明地球物理研究所,开展了川滇建设地区地震烈度区划,并在此基础上酝酿筹划地震预报的研究工作。1970年通海强烈地震发生以后,全面展开了地震预报的实验
Introduction The geotectonic movement in Yunnan Province is complicated and violent with high frequency and strong intensity of seismic activity. It is a multi-earthquake area. Since the completion of Kunming Seismostation in 1957, great progress has been made in the earthquake work in Yunnan in 1965 by establishing the Kunming Institute of Geophysics, Chinese Academy of Sciences, and carrying out the seismic intensity division in the construction area of Sichuan, Yunnan and on this basis, Forecast research work. After the strong earthquake in Tonghai in 1970, an earthquake prediction experiment was carried out in an all-round way
