Abstract

Paleoseismological studies in the source zone of the Tsetserleg earthquake of July 9, 1905 with M = 7.6–7.7 were carried out. Ruptures of three strong earthquakes were recorded in the studied sections. According to the results of the study of seismic ruptures in trenches, in addition to the earthquake of 1905, two strong rupture-forming earthquakes have occurred here over the past 3336–3454 years. The dating of penultimate event in the section of deformed floodplain sediments is 1309–1455 BP. According to the obtained data, the average recurrence period of the strong earthquakes along the Tsetserleg fault is 1100–1300 years.
