摘要
The Wenchuan earthquake 2008 caused a wide range of notable co-seismic and post-earthquake responses in fluid observation. The authors find the stations with notable change of near-field fluid observation by analysis of the data. Based on theoretical calculations of pore pressure changes caused by perpetual deformation with the earthquake, the authors discuss the physical mechanism of notable coseismic and post-earthquake changes in fluid observation. Then, in order to investigate the special characteristics of fluid effects caused by strong earthquakes, the authors separately calculate fluid response with different faulting styles and different magnitudes.
