| 摘 要： | 本文介绍了1990年12月独联体境内伊塞克湖Ms6.7地震和1991年2月新疆柯坪Ms6.5地震前,乌什地震台石英水平摆倾斜仪观测资料出现的异常变化。6.7级地震的累积异常量级为1.3×10~(-4),持续时间为两个月。6.5级地震的异常量级为8.5×10~(-70,持续时间27天。本文还就两次地震的预报及形变异常与地质构造之间的关系等进行了分析讨论。

| Abstract: | The abnormal change of tilt data obtained by quartz pendulum tiltmenter at Wushi station before Ms 6.7 earthquake occurred near Yisaike Lake of Russia in Dec. 1990 and Ms 6.5 earthquake occurred in Keping of Xinjiang in Feb. 1991 were introduced in this paper. The order of accumulated anomaly of the Ms 6.7 earthquake was 1.3×10-4,and its anomalous duration was two months. The order of accumulated anomaly of the Ms 6.5 earthquake was 8.5×10-7, and its anomalous duration was 27 days. The prediction about the two quakes and the relationship between their deformation anomaly and, the geological structure were also analyzed and discussed. |
