Abstract

The baytap08 program Is used to study the phase shift of the water level relative to gravity in wells in Georgia. In the extreme east of Georgia (Lagodekhi) and in the west (Kobuleti, Black Sea), the phase shift is <0 (from -25° to -60°). In the central part of the country, the phase shift is ≥ 0: Marneuli (center, south) about 0°; Nakalakevi (center, south, west of Marneuli) from +0.8° to +1.6°; Gori (center) +10°; Oni (center, northwest of Gori) from +15° to +26°. Note that among the specified wells, those with a positive phase shift turned out to be sensitive to remote earthquakes.
