The aim of the project is to determine earthquake source parameters (M0, Δσ, r0, Es, Δσapp) on the base of P and S waves spectra according to the Brune’s model using digital data for earthquakes that occurred in Georgia, to develop regional scaling laws, to study self-similarity of earthquakes spectra, to examine the behaviour of source parameters before and after strong earthquakes, to characterize the main seismogenic faults of Georgia by the earthquakes focal mechanisms connected with them, to create the uniform seismic catalogue of Georgia from 1955 up to now.
