|Abstract:||Approach to methodology of earthquake’s forecasting developed and evaluated since 1980 up today. At first was developing a hydro-chemical network on the territory of all Caucasus. During observations a lot of anomalies were fixed, but because of the diversity of chemical water content it was impossible to conduct observations of the unified parameters for creating the complete picture of strains on the whole territory. This is the reason why we decided to conduct observations for those parameters which could fix tidal variations with deformation of 10-8 degree, what is compared with strains differences during earthquakes preparation period. Besides, it was possible to conduct unified observations. Water level in the deep boreholes was one of them. That way since 1985, the network of 10 boreholes of different depth (from 250 up to 3500 m) covers the whole territory of Georgia. Boreholes characterize all basic geo-plates and open waters of deep aquifer, actually they represent sensitive volumetric strainmeters, and react on the deformations about 10-7-10-8, caused both by endogenous, and exogenous factors. A borehole was considered informative if it was fixing tidal variations and was included in the network. Special monitoring equipment is installed at boreholes which record several parameters, i.e. water level and micro-temperature, atmosphere pressure and surface temperature, tilt, magnetic field and others. Data is collected by datalogger XR5-SE-M. The data can be gathered in real time using the GSM net. Frequency of data collection is 1 minute. For the visualization and manipulation of data using special program which are developed at M. Nodia Institute of Geophysics.|
