SEISMICITY IN THE MIDDLE URALS AND BUILDING IN THE REGION


The article provides a characteristic of seismicity in the central part of the Ural region and its impact on engineering structures for the purpose of contribution to the seismic safety of engineering structure, both built and planned for building or reconstruction.

Data gathering and processing have been carried out concerning the seismicity of the central part of the Ural region, maps of observed tremor magnitudes during 1788-2010 have been compiled, and analysis of spatial location of the epicentres of notable earthquakes (a score of 3-4 by the MSK-4 scale and over), as well as distributions of earthquake magnitudes and intensities in time have been estimated. These data have been used to estimate the seismic potential of the earth crust in the central part of the Ural region, the seismotectonic conditions and the nature of the centres of the strongest earthquakes. Detailed seismic zoning of the central part of the Ural region has been carried out.

It has been established that the Middle Urals is the most seismic area of the latest Ural mountain belt. It has the greatest part of epicentres of notable earthquakes.

Generally, the seismic engineering conditions of the Middle Urals are estimated as favourable and safe for the majority of engineering projects. This is due to the low seismic and tectonic activity of the earth crust in the Middle Urals and favourable seismic conditions for the grounds of the region. Anti-seismic action in the central part of the Ural region is important only for designing and building particularly critical projects in respect of seismic safety – mainly high-rise buildings of 40 and more storeys, and other critical projects.
