| 摘 要： | 本文着重分析讨论了1989年10月和1991年1月两次中强地震前后重力异常变化及其与地震的对应关系。对1991年1月29日(代县至原平一带)5.1级地震的探讨性分析预报,说明流动重力测量在中长期地震预报中可以发挥重要作用。

| Abstract: | In this paper, the anomaly variations of the gravimetric value before and after both Datong-Yang-gaoM_s=6.1 (1989) and Daixian-Yuanping M_9=5.1 (1991) earthquakes and the relation between the anomaly variations and the earthquakes are discussed in detail. Through the elementary forecast of Daixian-Yuanping earthquake ,it is shown that the mobile gravity measurement may play an important part in the seismic prediction. |
