A STRONG EARTHQUAKE OF 2003 IN GORNYI ALTAI
Аннотация и ключевые слова
Аннотация (русский):
The aim of this paper is to describe the macroseismic, geological, and seismological manifestations of the strong earthquake that occurred in the south of the Gornyi Mountainous Altai area on September 27, 2003. The earthquake caused damage to buildings and constructions in the area of the Chuya and Kurai depressions and was accompanied by the manifestation of the earthquake source on the ground surface with the formation of a system of WNW-oriented faults, which has been traced over a distance of 20km in the region of the eastward plunge of the North Chuya Range. Secondary seismic dislocations manifested themselves in the form of rockfalls, landslides, and griffons in the area of the pleistoseist zone. The results of the preliminary study of the tectonic position of the earthquake source suggest that the Gornyi Altai is a direct continuation of the Mongolia and Gobi Altai areas, where earthquakes with magnitudes of more than 7.0 were recorded repeatedly, and allow us to combine all of the mountain systems of the Great Altai into one high-magnitude seismotectonic province.

Ключевые слова:
