However, the screened intervals in the wells of this study are mostly too deep to discharge groundwater to surface. (4) Diffusion of a localized coseismic pressure change: earthquakes cause a localized change of fluid pressure and lead to the changes of water level in the wells owing to pore pressure diffusion. To induce pressure changes by seismic waves require a physical mechanism such as earthquake-induced liquefaction or removal of gas from the pore space
