This article aims to enhance seismic hazard assessment methods for Kazakhstans seismotectonic conditions. It combines probabilistic seismic hazard analysis (PSHA), ground motion simulation, sitespecific geological and geotechnical data analysis, and seismic scenario analysis to develop Probabilistic General Seismic Zoning (GSZ) maps for Kazakhstan and Probabilistic Seismic Microzoning maps for Almaty. These maps align with Eurocode 8 principles, incorporating seismic intensity and engineering parameters like peak ground acceleration (PGA). The new procedure, applied in national projects, has resulted in GSZ maps for the country, seismic microzoning maps for Almaty, and detailed seismic zoning maps for East Kazakhstan. These maps, part of a regulatory document, guide earthquake-resistant design and construction. They offer a comprehensive assessment of seismic hazards, integrating traditional Medvedev–Sponheuer–Karnik (MSK-64) intensity scale points with quantitative parameters like peak ground acceleration. This innovative approach promises to advance methods for quantifying seismic hazards in specific regions.
