In the present study a set of two deterministic earthquake scenarios (expressed in peak ground acceleration and macroseismic intensity MSK) are generated for the city of Sofia - the capital of Bulgaria. The study is guided by the perception that usable and realistic, based on both local seismic history and tectonic setting, ground motion maps to be produced for urban area. The city is situated in the center of the Sofia area that is the most populated (the population is of more than 1.2 mil. inhabitants), industri...

In the present study probabilistic earthquake, scenarios for the city of Varna the third-largest earthquake-prone city in Bulgaria are presented. The probabilistic hazard for a city is obtained by integrating the effects of ground motion from earthquakes of different size occurring at different locations within different seismic source regions and with different frequencies of occurrence. The ground motion maps for the city of Varna are generated combining via GIS, source geometry, earthquake occurrence model, max...
