SEISMICITY OF THE REGION OF THE TUNKA BAS INS ON THE SOUTHWESTERN FLANK OF THE BAIKAL RIFT IN THE LIGHT OF EXPERIMENTAL-OBSERVATIONS CARRIED OUT IN THE 2ND HALF OF THE 20 CENTURY

The generalized data on the seismisity of the Tunka basins region on s outhwestern flank of the Baikal Rift Zone, which were accumulated by t he end of the XX century, are presented. The field of the epicenters o f the earthquakes concentrated in three zones bounding aseismic or muc h less seismic regions is studied. These zones not always coincide wit h zones of faults. The average recurrence of earthquakes of various en ergy in the zones is estimated. The earthquake mechanisms indicate var ious types of Focal motions. The position of a new June 29, 1995 earth quake, which is comparable with the largest earthquakes in the region under study in the XIX century, in the seismic process is analyzed. It s epicenter is located at the eastern edge of the zone with the greate st concentration of earthquake epicenters, in the Tunka basin.
