EARTHQUAKE HAZARD ASSESSMENT INDIA AND ADJACENT REGIONS (HB 2018) Paperback

This book makes a significant contribution to earthquake data processing and the creation of region-specific magnitude correlations to develop a modern, consistent earthquake catalog with a uniform magnitude scale. It covers seismicity analysis and the estimation of seismic parameters for both small and large regions using various methodologies. The book also addresses the identification and characterization of regional seismic source zones, which requires careful observation and engineering judgment. Given the region's complex seismotectonic features, it elaborates on the use of multiple approaches (DSHA and PSHA) in seismic hazard analysis, incorporating tools like the logic tree to account for epistemic uncertainties. It considers alternative models for source modeling, Mmax estimation, and ground motion prediction equations to calculate the Peak Ground Acceleration (PGA) at bedrock level. Additionally, it discusses the characterization of VS30 based on topographic gradients to help create surface-level PGA maps using relevant amplification factors. The book also explains the evaluation of probabilistic liquefaction potential. These topics are explored through a case study focused on India, which features complex and varied tectonics. The methodologies and findings presented will be valuable for engineers and researchers in seismology and geotechnical engineering, as well as for society at large.
