| 摘 要： | 地震的发生与地球自转和极移的惯性力的作用密切相关，在惯性力的作用下地壳岩石内产生应力应变。用四方位地应变传感器观测水平地应力应变变化规律和临震前兆信息－地应力应变剧烈变化和地壳岩石出现微观断裂滑移及微观弹塑性应变应变波群，再根据主压应力作用方向和地质构造断裂带分布情况作综合分析，可以在临震前１０￣７２小时内初步预报出地震的时间、方向、地点和震级。对于震中距４００公里内的中强地震预报对应率较高，根据

| Abstract: | The natural earthquake is in close relationship with the effect of inertial forces produced by the earth rotation and the pole migration. The stress-strain is produced in the crustal rock under the action of inertial. We can detect the variation regulation of horizontal ground stress--strain with the four-azimuth sensor of underground strain I also detect the information of impending earthquake precursor--the intense variation of under-ground stress--strain produced before some earthquakes occurring, the micro fault slip of crustal rock and the wave groups of micro elastoplastic stress--strain. We combine the information with the direction of principal compressive stress and the fault distribution in the geologic structure for comprehensive analysis. Then we can predict the time, direction. place and magnitude in 10--72 hours before any earthquake occurring. The high ratio of mid--strong earthquake prediction can be taken with this method for the epicentral distances are no more than 400 kilometers.According to our prediction experiments, there are some false predictions but no a failure. |
