Seismic Microzonation of New Tashkent Territory Based on Analysis of Peak Ground Accelerations
Abstract
This study assesses seismic impacts on the territory of New Tashkent through a comprehensive analysis of seismological, seismotectonic, and geological data. Potentially hazardous seismic zones were identified, and their maximum seismic potential (Mmax) was estimated, leading to the construction of spatial distribution maps. Seismic impact intensity at construction sites was evaluated using the MSK-64 scale with probabilistic thresholds over a 50-year period. Engineering-geological studies, including electrical exploration and seismic microzoning, were conducted to refine local seismic conditions. MASW-based field investigations at 98 observation points were conducted and modelled in Strata software to assess seismic response. These findings contribute to improved seismic hazard assessment and risk mitigation strategies for future developments of the territory of New Tashkent.
