Chilean Earthquakes: Aquifer Responses at the Russian Platform

We studied hydrogeological responses to the passage of seismic waves from the Chilean earthquakes with Ms ≥7.6 at epicentral distances of about 126°. The variation in the levels of confined and unconfined aquifers was analyzed under platform conditions at the Mikhnevo Geophysical Observatory near Mo...

Description
Summary:We studied hydrogeological responses to the passage of seismic waves from the Chilean earthquakes with Ms ≥7.6 at epicentral distances of about 126°. The variation in the levels of confined and unconfined aquifers was analyzed under platform conditions at the Mikhnevo Geophysical Observatory near Moscow, Russia. Synchronous recording of seismic and hydrogeological data enabled us to evaluate the amplitude–frequency response of aquifers. The study shows that medium response to dynamic impact depends on various physical parameters of the aquifers.
