SEISMIC REFLECTION OF COMPLEX GEODYNAMIC PROCESSES IN THE OROGENES OF THE GREATER AND LESSER CAUCASUS

Abstract

Within the following paper reflections of the space-time development of seismisity for the period (1900-2000) on the large Erzurum-Borzhomi-Kazbeki (EBK) seismic lineament in the geodynamics of the orogenes of the Greater and Lesser Caucasus are considered, as well as its relation to the identified geodetic and morphostructural data of modern movements of these orogens. Seismic activation periods obtained through seismological data and the time intervals of relative seismic calm concluded between them adequately reflect the short-term epochs of lowering and raising the orogens of the Lesser and Greater Caucasus, identified by geodetic data. The obtained results allow using seismological data for the reconstruction of modern movements, as well as in studies aimed at solving the problem of long-term earthquake prediction.
