| Abstract: | 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 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 ... |
