چکیده مقاله:

The new study of seismogeodynamics and seismic zonation for North Eurasia is based on the idea of a structural, dynamical and energy unity of the geophysical medium and the seismogeodynamic processes going on in it. A homogeneous seismogeological data base has been compiled for North Eurasia and a 3-D lineament-domain-focal model of earthquake source generation has been developed. A set of new General Seismic Zonation (GSZ) probability maps has been made for North Eurasia, including the Russian Federation and adjacent seismic regions.The GSZ maps of Russia being accepted as the basis for the national Building Code. The probability of a possible exceedance of seismic intensity within 50 years shapes up as follows: 10 percent (map GSZ-A), 5 percent (GSZ-B), 1 percent (GSZ-C) and 0.5 percent (map GSZ-D). The GSZ-A map was recommended for the construction of residential, public and production buildings;the B and C-maps for the objects that should continue in service even during earthquakes and also for premises housing a large number of people; the GSZ-D map for such high-danger objects as nuclear power stations etc.The Government has ratified the Federal Program - “Seismic safety of territory of Russia” (2002-2010). The purpose of this Program is the maximal increase of seismic safety of the population,reduction of social, economic, ecological risk in seismically dangerous areas of the Russian Federation, decrease of damages from destructive earthquakes by certification, strengthening and reconstruction of existing buildings and constructions, and also preparation of cities and other settlements, transport, power constructions, pipelines for strong earthquakes
