ROSTOV-ON-DON, November 28 — RIA Novosti, Yulia Nasulina. Scientists at the Institute of Physics of the Earth RAS named Schmidt to 2014 will create a detailed map of seismic zoning of the North Caucasus, which will be considered as paleoseysmicheskie and instrumental investigations, said the deputy director of the Institute Yevgeny Rogozhin on Monday at the International Conference "Seismic safety of the Black Sea region."
As explained Rogozhin RIA Novosti, separate seismic zoning map of the Caucasus today is not, and the corresponding map of the country was last updated in 1997 and contains a number of errors. For example, Krasnodar, according to the map, there is a nine-zone (on a scale of earthquake intensity MSK-64 — Ed.), Although, according to the scientist, the threat level was not above 7-8 points — and Salsk steppes, on the contrary, are in a five-point area, although there was an earthquake registered 6.7 points.
"Now there is a need to make a new map detailed seismic zoning for the North Caucasus on a completely new level," — said. He added that the institute has won a lot in the creation of this card as part of Russian Emergencies Ministry to reduce the risks of natural and man-made disasters. The document should be developed before 2014.
Rogozhin said that such a map is essential for the Caucasus region, where the population density is associated with low quality of construction and high risk of earthquakes. These factors make the Caucasus is much more vulnerable to seismic risk than, for example, you men of the Far East.
A new level of development will be determined using the card in it as paleoseysmicheskih data and instrumental studies. Paleoseysmicheskie data include analysis of faults and deformation of the soil to determine the previous seismic events and their frequency, and are very important because of the relatively short period of monitoring of earthquakes in Russia. In this case, instrumental studies largely based on data from seismic stations.
"We have already collected most paleoseysmicheskih data for the North Caucasus, but in order to use them to assess the real seismic risk, we proposed to schedule the frequency from seismological data, also includes instrumental observations," — said Rogozhin, stressing that the data for the first time paleoseysmicheskie used in such a way to assess the seismic hazard in the region.
Seismic zoning map of the North Caucasus, according to him, will enable a medium-and long-term prediction of earthquakes in this region.
