Reaction of the fluid saturated collector during passage of seismic waves

Precision monitoring of the groundwater level has been carried out at the territory of the Mikhnevo geophysical observatory since 2008. Observations are conducted in two wells, which expose confined and unconfined aquifers. The paper considers the reaction of a fractured-pore reservoir to seismic waves from distant earthquakes. A comparative analysis of hydrogeological effects associated with the passage of seismic waves from distant earthquakes is performed in the high- and low-frequency ranges.
