Traces of ancient earthquakes in the Altai mountains

Abstract

Paleoseismogeological field researches in the south-eastern part of Altai Mts. took place in the 1996- and 1997. Seismodislocations of earlier unknown earthquakes was found in this region; their mapping and investigation ill the mine-workings were fulfilled. Primary seismodislocations may be-seen in recent landforms as low cliffs of large extent and as thrusts in cross-sections. Landfalls, landslides and stone avalanches represent secondary seismodislocations. Their C¹⁴ dating lies in the range 8000-200 b.p. The data obtained allow considering the south-east part, of Altai Mts. region to be apparently high seismic.
