Conference Paper
Full-text available
The research is focused on the study of criteria in defining the scenario earthquakes for the deterministic seismic hazard analysis. Deterministic approach in seismic hazard analysis is a worldwide applied method. In deterministic analysis, the effect of the scenario earthquake is considered. Scenario earthquake is supposed to be the most severe ea...
