The information on the Baikal region strong earthquake focal mechanisms has been summarized in the schematic map of the epicenters, density contours and the representativity table. The structure and basic regularities of focal mechanism complete sample are formed by quantitatively dominating impact faults. Conformance of the average incidence angles DPaver and the average SLIP moduli of thrust-faults and faults does not rule out a possibility of adjustment movements of these types only on fault planes. The average incidence angles for different slip types exceed 50o that evidences on the rather steep pitch of fault zones.
