Seismic risk assessment for the Greater Sochi area

Аннотация

Earthquakes, among other natural phenomena, often cause loss of life and significant economic damage. According to the statistical data of the International Centre for Research on the Epidemiology of Disasters (www.cred.be), earthquakes are among the leaders in all aspects: the number of fatalities, the number of injured, and the caused economic loss. The widely accepted strategy for reducing the damage and social losses implies preventive measures in high-risk zones identified by mapping with different details. About 5% of RF territory is referred to the areas characterized by a high level of seismic hazard, where earthquakes with intensities I = 8–9 and 9–10 by the MMSK-86 scale may occur. The Caucasus is among the most hazardous and densely populated regions in the country. During the preparation to the 2014 Olympic Games, the individual seismic risk was assessed for the Greater Sochi territory including the Olympic sites. The paper analyzes the results of seismic risk monitoring, obtained in 2007 and 2013.
