| Abstract: | The dynamic strain variations and co-seismic groundwater level changes associated with May 2008 Sichuan, China Earthquake (Mw7.9) were observed at TGR350 and SZB (97FT-01, SN-1 and SN-3) at Tono area, Gifu Prefecture, Central Japan. We investigated the relationship between the hydroseismogram and the dynamic strain variations observed at each observatory. The following results were obtained: As for the TGR350, the observed co-seismic groundwater level change was caused by dynamic strain variation with peak-to-peak amplitude of order of 10^[-6] strain. As for the SZB (97FT-01, SN-1 and SN-3), the observed co-seismic groundwater level changes in SN-1 and SN-3 were also caused by dynamic strain variation with peak-to-peak amplitude of order of 10^[-6] strain. |
