| 摘 要： | 结合区域地质构造资料 ,对银川台记录到的灵武、吴忠地区地震资料中出现的方位异常现象进行了探索性的分析。认为受贺兰山山前断裂构造和震中所在地地质构造的影响 ,银川台记录到的地震波形发生畸变 ,而波形畸变又造成了方位异常。

| Abstract: | Combined with the data of geological structure in the Yinchuan area,the earthquake azi muth anomalies in the Lingwu Wuzhong area recorded by Yinchuan Station are discussed and analyzed.Affected by Helan piedmont fault and the geological structure in the area,the seismic wave forms recorded by Yinchuan station show distortions,and the distortions cause the azimuth anomaly. |
