Abstract
We discuss the results of study of the Holocene seismic activity in the zone of the Hustai Fault, Central Mongolia. Applying seismological methods (remote, trenching, geophysics), we have revealed signs and determined the quantitative parameters of the paleoearthquake that led to the fault dissection at 3.0–5.5 ka. The high seismic potential of the Tola zone and its proximity to Ulaanbaatar confirm earlier estimates of the seismicity of the capital of Mongolia, 8 points on the MSK-64 scale.
