We studied fault scarps produced by prehistoric earthquakes in the Barguzin fault zone and estimated the ages and the magnitudes of the scarp-forming events in each scarp segment from their structure, morphology, and scarp parameters. Morphological and structural data reveal two to four surface-rupturing events with displacement up to 5-9.5 m, and two events showed (super 14) C ages of 4.5 and 9 kyr. The area of the Barguzin Fault may have experienced six 7.5 < or = M < 8.0 earthquakes and two M > or = 8.0 (8.0-8.2) events for the past 10-12 kyr.
