摘要
应用畸形参数附带卓越周期拟合法 ,结合其他跨断层形变资料处理方法 ,处理了泾阳短水准资料 ,提取具有定量性质的形变异常特征 ,较好地反映了泾阳 ML 5.2地震前兆信息。且震前形变异常存在着以
In this paper,the short levelling data of Jingyang was processed by the fitting method of distortion parameter with distince period and the other methods for processing across fault deformation data.The obtained quantitative deformation anomalous results which have the frequency feature with multiple of 3 before earthquakes reflects the precursor information of Jingyang earthquake with M L=5 2.
