In the present study deterministic earthquake scenarios for the city of Varna - the thirdlargest city in Bulgaria are presented. By deterministic scenario, it is mean a representation of the severity of ground shaking over an urban area, using one or more hazard descriptors. The assessment of seismic hazard and generation of earthquake scenarios is the first step of seismic risk evaluation and society prevention. Seismic history of Varna shows that the hazard for the city is mainly influence by the earthquakes occ...

-he space-time distribution of earthquakes is of substantial importance for understanding the physics of the earthquake generation process. Earthquakes can be analyzed as a time series of events that result from the released strain in the earth's crust. The study of the space-time distribution of earthquakes using statistical methods reveals many of their characteristics. Sequences of seismic events affect both spatial and time distribution of earthquakes. It is necessary to know the statistical characteristics of...
