DETAILED SEISMIC ZONING OF THE CENTRAL PART OF THE URALS REGION


Engineering facilities in the Middle Urals are exposed to some adverse natural factors, one of which is rare but perceptible earthquakes of intensities from 3–4 to 5–6 by the MSK-64 scale. These earthquakes are accompanying the ongoing formation of new Ural mountains and make up the subject-matter of our study.

The objective of the study is to contribute to the seismic safety of engineering facilities in the central part of the Ural region. To this end, a detailed seismic zoning map of the Ural region’s central part has been carried out, the results of which can be useful for estimating the strength of a seismic impact on engineering facilities to be constructed or reconstructed.

The seismic zoning methodology was based on the use of available data on perceptible seismic shocks in the Middle Urals and on the use of the seismo-tectonic (seismo-geological) approach.

The seismic zoning of the central part of the Ural region has helped identify a potentially seismic area within which natural earthquakes of intensity up to 5–6 by the MSK-64 scale are likely to happen. The area covers the Middle Urals and adjoining parts of the Northern and Southern Urals extending in the northwest direction corresponding to the direction of the basic geological tectonic structures of the region.

The seismic zoning map of the Middle Urals is recommended to be used for estimating the degree of seismic impact on engineering facilities to be built or to be reconstructed.

Key words: seismicity, epicentres of earthquakes, magnitude, seismic zoning, potentially seismic are
