On base of specialized hydrogeological observations data in seismic regions (Japan, USA, Armenia, Kamchatka) are considered seismic influence on groundwater regime. In underground water regime are revealed specific types of changes by seismic influence. These types are revealed subject to kinds of seismic effects, sorts of regime objects (springs and self-flowing wells, piezometric wells), as well as discrepancy of hydrogeoseismic effects formation in head water-bearing systems containing sweet groundwater without gas and gas-saturated groundwater.
