Reaction of the Hydrodynamic Network on the Earthquake Preparation Process in Georgia

The article contain information about several hydrodynamic anomalies were observed during earthquake in Racha (04.11.2020 17:10, Mag = 4.2, Depth = 2km, Lat. 42.48°; Long. 43.41°) on the multiparametric monitoring network of M. Nodia institute of Geophysics. Data were analyzed by the special program which gives possibility to exclude the influence of geological factors by the common value of tidal variations. Was analyzed reaction of parameters to the earthquake preparation process.
