Coseismic static stress changes and dynamic stresses generated by seismic waves cause
changes in water level in wells and in stream flow and alter hydrogeologic properties such …

We analyze the co-seismic groundwater level responses to four great earthquakes recorded
by China's network of groundwater monitoring wells. The large number of operational wells …

We performed continuous recordings (May 2015–January 2017) of hydraulic pressure and
electrical conductivity of groundwater in the 190 m-long horizontal S13 borehole drilled next …

The transfer functions of the well‐aquifer systems response to atmospheric loading and
Earth tide can be used to calculate the well‐aquifer properties. Due to the low signal‐to …

Porosity waves correspond to a steady‐state solution to the coupled hydraulic and rheologic
equations that govern the flow of the fluid through the matrix and matrix deformation. This …

Coseismic groundwater‐level changes induced by earthquakes have been reported for
thousands of years. The M8. 0 Wenchuan earthquake caused coseismic groundwater‐level …

Generation and maintenance of overpressure can prevent sediments from compaction and
weaken sedimentary rocks in deep basins. Excess fluid pressure is one of the key factors to …

Oscillations of water pressures and crustal strains due to the seismic waves of the 2010
Chile earthquake were observed in Japan. The oscillations of water pressures observed …

Travelling seismic waves and Earth tides are known to cause oscillations in well water levels
due to the volumetric strain characteristics of the ground motion. Although the response of …

Pore pressure decreased at the Kamioka mine in central Japan after the Tohoku earthquake
(M9. 0) on 11 March 2011, which can be attributed to a permeability increase. We focus on …
