Abstract

The M_W 9.0 earthquake occurred in the northeastern Sea of Japan, on March 11, 2011.The volume strain meter in Wenchuan earthquake Fault Scientific Drilling (WFSD) recorded a complete response waveform at Hanzhong Prefecture, Shaanxi Province.By analyzing acquired data, some issues are studied and discussed by authors that including co-seismic changes of the whole process of M_W 9.0 mega-earthquake in Japan, the abnormal strain changes of solid tide prior to that earthquake and after, and the emerging process of that earthquake.Per this paper, the strain anomalies of the M_W 9.0 earthquake in Japan are analyzed in order to contribute to better forecast earthquake trends in China the future.
