应用气象卫星轨道摄动反演地壳区域构造应力降动态场 ,对广大地区进行快速扫描获取地震近源区和震源区短临阶段孕震发震前兆场 ,藉以预测地震三要素———震中、震级和发震时间 ,以期达到预报地震如同预报气象 .对近年来滇西北地震的震例正演计算了丽江、武定强震并绘制其地震前、后应力降动态特征图及其强震前兆应力降异常波动发震时间曲线图
Using meteorological satellite orbital perturbation to inverse the tectonic stress drop dynamic field in the crust, the rapid scanning of the vast area can be used to obtain the precursory earthquake-onset precursory field near and far in the near- Magnitude and seismogenic time in order to reach the predicted earthquake as predicted weather.For the earthquake cases in northwestern Yunnan in recent years, the strong earthquakes in Lijiang and Wuding are calculated and the dynamic characteristics of stress drop before and after the earthquake are plotted and the prestress stress drop of strong earthquakes Abnormal fluctuations in seismogram time curve
