摘要
本文根据山西长治和代县地应力站的观测资料,深入分析了大同一阳高6.1级地震前地应力异常变化特征。地震前地应力的变化不仅有趋势异常,而且还有明显的短期和临震异常显示。其异常变化的总趋势是:下降—持平—回升。根据地应力异常变化,作者曾作了较准确的短期预报。
This paper deals with the anomalous features of crust stress change, based on the data observed at Changzhi and Daixian crust stress stations in Shanxi province before the Datong-Yanggao Ms6.1 earthquake. There are not only tendeney anomalies, but also short term imminent anomalies. The general tendency is : decline—unbiased—rising. The author made a more accurate short-term prediction before the earthquake, based on the anomalous change of crust stress.
