- Abstract:
-
Earthquakes can affect hydrogeologic process in a very large scale. Studying how earthquakes affect groundwater flow can help us to understand the interaction between earthquakes and the groundwater. The coseismic response of the groundwater has been studied for nearly 90 years. It has revealed that the coseismic response of the groundwater is a very complicated process. The coseismic response of the water level in the well directly reflects the local hydrogeologic process after an earthquake. There are three major types of coseismic changes of the water level in the well: step-like changes, sustained changes and water level oscillations. The mechanism for coseismic water level changes is complicated, even for the same type of water level changes, the mechanisms could be different. We review the responses of the well water level to earthquakes and summarize our current understanding of the processes causing the water level changes in the well. Comparing different coseismic well water level responses and mechanisms,we can have a better understanding of the physical processes for the coseismic response of the water level in the well.
