【Abstract】 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.更多还原
