Abstract

Summary

Earthquakes adversely affect large parts of the Earth. Global seismic risk and vulnerability to earthquakes are increasing steadily as urbanization and development occupy more areas that a prone to the effects of strong earthquakes.

The territory of Bulgaria represents a typical example of a high seismic risk area in the eastern part of the Balkan Peninsula. Over the centuries, Bulgaria has experienced strong earthquakes. Some of Europe`s strongest earthquakes in the 20th century occurred in the territory of Bulgaria.

The present study is a comprehensive earthquake scenario study. A deterministic earthquake scenario for the city of Veliko Tarnovo is generated. The study is guided by the perception that usable and realistic ground motion maps have to be produced for urban area. The local ground shaking levels are computed using six ground motion prediction equations (GMPE’s). The scenario maps account for soil amplification effects using the geotechnical zonation of the considered urban area. The results show that macroseismic intensity varies between 8.3 and 8.6 MSK, the peak ground acceleration and velocity vary between 0.30 and 0.37 g, and 26.9 and 38.5 cm/s, respectively.
