摘要
The Mw9.0 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 the authors that including co-seismic changes of the whole process of Mw9.0 mega-earthquake in Japan, the abnormal strain changes of solid tide prior to that earthquake and after, and the emerging process of that earthquake. In this paper, the strain anomalies of the Mw9.0 earthquake in Japan are analyzed in order to contribute to better forecast earthquake trends in China in the future.
