Probabilistic Seismic Hazard Assessment for Romania

This chapter presents a seismic hazard model for Romania and the results obtained within the framework of the BIGSEES national research project (http://infp.infp.ro/bigsees/default.htm) financed by the Romanian Ministry of Education and Scientific Research in the period 2012–2016. One of the most important objectives of the BIGSEES Project is to provide a refined and updated seismic hazard map for a further revision of the seismic design code in Romania. To this aim, the seismicity of all sources influencing the Romanian territory are analyzed, the ground motion prediction equations to be used in the analysis are graded and a comprehensive sensitivity analysis is performed. Both aleatory and epistemic uncertainties are incorporated in the probabilistic seismic hazard analysis. The main results of the study presented hereinafter refers to seismicity parameters, logic tree branches' weights, seismic hazard curves and seismic hazard maps for peak ground accelerations and spectral accelerations, as well.
