New scientific results on the conditions of preparation and development of seismic processes in the Crimea-Caucasus region as well as the analysis of the seismicity in the vicinity of the city of Sochi are presented. On the basis of the long-term experimental observations there have been originally distinguished specific geomagnetic disturbances accompanying large seismic events on a regional scale. Comparative analysis with the results of similar observa-tions of magnetic disturbances associated with preparation and development of the deep-focus earthquake in Kamchatka allowed formulating a new paradigm for a seismic source structure.
