| 摘 要： | 采用A(b)值空间扫描方法对1975年以来东南沿海地区ML2.3到ML4．9级地震资料进行了研究。统计分析了Ms4．6级以上地震前A(b)值异常情况。结果显示大多数Ms4．6级以上地震发生前的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0．46。

| Abstract: | The data of earthquakes from M L 2.3 to M L 4.9 in the Southeast Coastal Region since 1975 are analyzed by means of A(b)-value spatial scan. The A(b)- value anomalies before the earthquakes with MS?Y4.6 occured are collected in numbers and studied. The result shows there were high-value anomalous areas with A(b)?Y5.0 around the epicenter one to three years before most MS,3/44.6 earthquakes occured. The R-value test comes to 0.46. |
