Probabilistic Liquefaction Hazard Assessment in Highly Stratified Alluvial Deposits Integrating Continuous In-Situ Profiling and Depth-Dependent Seismic Demand

This study demonstrates that relying on uniform peak ground acceleration assumptions underestimates liquefaction hazards in Kolkata's highly stratified alluvial deposits, revealing that integrating continuous in-situ profiling with depth-dependent nonlinear ground response analysis significantly increases the estimated probability of liquefaction to over 85% for loose granular layers under seismic scenarios.
