ABSTRACT

In this study, soils from two locations namely Rudrapur and Khatima from Uttarakhand, India adjacent to Himalayan Frontal Thrust (HFT) have been considered for response analysis. The in-situ and dynamic soil properties determined from undisturbed and disturbed soil samples are taken for earthquake response analysis. Three moderate magnitude earthquakes of Himalayan origin have been used to study the variation of PGA, PGD, and excess pore water pressure of the thick alluvial soil deposits. Present study suggests that an earthquake of magnitude of Mw ~ 4.7 to 6.5 will liquefy soils from Uttarakhand Plain in Himalayan region at a shallow depth.
