| 摘 要： | 讨论了新疆40年代以来所发生的8次7级强震前的围空现象。结果表明,除1974年巴里坤7.1级地震因资料不全外,7级强震前均出现明显的围空现象。研究发现,这种围空一般都经历了三个过程,时间通常为10—20年。最后分析讨论了7级强震前围空的特征以及判别指标。这将为今后确定强震危险区提供依据。

| Abstract: | The seismic gap phenomenon before 8 strong earthquakes of Ma =7occured in Xinjiang since 1940s was discussed. The result shows that the gap phenomenon appeared obviously before strong earthquakes of Ms =7(except before Balikun MS7. 1 earthquake in 1974 because there was no enough data to deal with) The research shows that the gap phenomenon generally undergoes three process which usually lasts 10-20 years. Finally,the characteristics and the criterion index of seismic gap before strong earthquakes of Ms = 7 were analyzed and discussed. This will provide evidence for de-terming seismic risk area in coming years. |
