摘要
1990年4月17日和1990年11月12日,在中国新疆乌恰和苏联巴依沙隆分别发生6.4级和6.7级地震。位于震中附近的中、苏交界地区在两次地震之前有多个地震窗呈现出明显的异常,并据此作出了较好的短期预报。本文简述了预报过程,着重分析了多个地震窗的综合异常特征。最后讨论了所得结果可能的物理机制等问题。
On April 17, 1990, a.Ms 6. 4 earthquake took place in Wuqia, Xinjiang, and on Nov. 12, 1990, a.Ms 6. 7 event occurred in Baiyishalon, USSR. Before the occurrence of the two quakes, obvious anomaly appeared at many seismic windows which near the epicenter in border area of China and USSR. Based on the anomaly, a short term prediction was made succesfully. The prediction process is summarized and the anomalous characteristics of these seismic windows are emphatically analysed in this paper. Finally, possible physical mechanism of these results are discussed.
