2 Seismic Hazard Scenarios

The seismic risk assessment was performed for the entire country, at the most detailed resolution available, which is the administrative-territorial unit. A total of 3186 units were considered in the analysis. The assessment of seismic risk was performed for hazard five scenarios, three of which were common to all the hazards’ assessment. The other two scenarios, required a more detailed analysis and were defined individually. The first three seismic hazard scenarios, considered the effect of all the seismic sources which can affect the territory of Romania. The seismic sources that can affect the territory of Romania are defined in Fig. 1. For each mean return period considered in the assessment, namely MRI = 10 years, MRI = 100 years and MRI = 1000 years, a classic probabilistic seismic hazard assessment (PSHA) was performed. In the case of the two deterministic earthquake scenarios, the peak ground accelerations were computed using two ground motion models (median amplitudes), namely the Vacareanu et al. (2015) model for the Vrancea intermediate-depth seismic scenario and the Cauzzi et al. (2015) for the Banat crustal scenario. The most recent delineation of these seismic sources was performed within the BIGSEES national research project and can be found in the paper of Pavel et al. (2016).
