Abstract:

The data for 5 years observed at 9 fixed crustal deformation stations were used to calculate the tidal factor and phase delay series before the Wenchuan Ms8.0 earthquake.It is shown that at 7 stations there were abnomal changes before the earthquake.The nearer the station located to epicenteris,the greater of the abnormal signal.However the abnormal signal from the two stations were not obvious before the earthquak,one was Maoxian which is 100 km away from the earthquake and another was Kangding which is 20...
