| 摘 要： | 采用A(b)值空间扫描方法对1980年以来河西走廊及其临近地区ML 2.3到ML 4.9地震资料进行了研究,统计分析了Ms 4.6以上地震前A(b)值异常情况,结果显示大多数Ms 4.6以上地震发生前的1-3年内,震中周围出现A(b)≥5.0的高值异常区域.R值检验结果为0.458.

| Abstract: | Spatial scanning method for A（b） value is used to study the earthquake data of ML 2.3 to ML 4.9 magnitude in Hexi Corridor and its adjacent areas since 1980. The anomalous A（b） value occurred before the earthquakes with magnitude Ms 4.6 or larger is statistical analyzed. The results show that 1- 3 years before the occurrence of most Ms 4.6 earthquakes, the high value anomalies of A（b） ≥ 5.0 appear around the epicenter. The R value of the test results is 0. 458. |
