Abstract：It was found that the abnormal changes of short leveling data at Jingyang station, Shanxi province appeared, which downslide southward in three months before Wenchuan Ms 8.0 earthquake. The similar phenomena appeared before the October 24,1995 Wuding Ms 6.5 earthquake,Yunnan, the December 18,1995 Maduo Ms 6.2 earthquake,Qinghai and the February 23,2001, Yajiang Ms 6.0 earthquake, Sichuan. The relation among magnitude (M), epicentral distance (L), anomaly amplitude (H) and anomaly duration (T) is M=0.002 8L＋1.126 9H＋0.076 8T by inversion method.
