New data on the late holocene seismicity of the southwestern edge of the Baikal Rift Zone

Abstract

Three strong earthquakes that occurred since the end of 8th century have been identified by archeoseismic data in the southwestern part of the Tere Khol’ Depression. The dates for these events are the 9th, 12th, and first two-thirds of 19th century, and the average recurrence interval is 500 years. The relative seismic passivity of the Tere Khol’ Depression at present may be related to the relatively recent discharge of stress in seismogenerating sources.
