Abstract:

The paper deals with the assessment of the seismic hazard of Moldova Republic based on the Eurocode 8 requirements for setting the probabilistic level of seismic effects. Unlike traditional methodologies, this study integrates deterministic elements into the probabilistic framework to enhance the accuracy of hazard estimation. A detailed geometric analysis of the Vrancea focal zone—the primary source of seismic hazard for Moldova—was conducted, and two mathematical models for earthquake intensity were developed. Finally, new seismic hazard maps for the territory of Moldova were created in terms of both of MSK—intensity and acceleration. Compared to previous maps, the new version offers higher reliability and can serve as a foundation for updating the Seismic Regulatory Codes of the Republic of Moldova.
