| 摘 要： | 就库尔勒台用高精度RZB - 1型宽频带数字应变仪先后在 5 0 0km范围内记录到的几次较典型的MS5 .5左右地震的前兆异常作了初步分析与探讨 .结果发现 ,震前测值曲线异常形态虽说各有所不同 ,但却有一些共同的特征 :固体潮畸变 ,应变速率加快 ,易出现临震突跳 ,应变阶跃等 .根据这些特征 ,我们对 1 993年 2月 3日和静MS5 .7地震、1 993年 1 0月 2日若羌MS6 .6地震和 1 996年 1月 9日沙湾南MS5 .4地震作了不同程度的预报 .

| Abstract: | Primary analysis and discussion on some typical earthquake precursor anomalies which appear in the range of 500 km are done according to the data recorded by the RZb-1 type digital strain gauge with high precision and broad channel.The results show that though there are some differences on the observed curve anomaly forms before the earthquake,there also exist some same characteristics such as solid tide distortion,strain rate increase,impending earthquake abrupt anomaly,strain step,etc.According to these characteristics,authors predicted the earthquakes,for example,the Hejing M S5.7 earthquake on Feb.3,1993,the Ruoqiang M S6.6 earthquake on Oct.2,1993 and the south Shawan M S5.4 earthquake on Jan.9,1996. |
