The analysis of field investigation data together with aerial and space images of the region of the Racha earthquake (the strongest one at the Caucasus) revealed most irregular distribution of seismic- gravitational surface deformations within the epicentral zone. Lateral and vertical unhomogeneities in the field of tectonic jointing as shown by tire space images permitted to outline a series of moving blocks of the earthcrust and to explain the observed differences in seismological and geological manifestations in the western and eastern epicentral zone.
