Site-specific seismic hazard analysis is crucial for designing earthquake resistance structures, particularly in seismically active regions. Shear wave velocity (
V S) is a key parameter in such analysis, although the economy and other factors restrict its direct field measurement in many cases. Various
V S–SPT–
N correlations are routinely incorporated in seismic hazard analysis to estimate the value of
V S. However, many uncertainties question the reliability of these estimated
V S values. This paper comes up with a statistical approach to take care of such uncertainties involved in
V S calculations. The measured SPT–
N values from all the critical boreholes were converted into statistical parameters and passed through various correlations to estimate
V S at different depths. The effect of different soil layers in the boreholes on the
Vs estimation was also taken into account. Further, the average shear wave velocity of the top 30 m soil cover (
V S30) is estimated after accounting for various epistemic and aleatoric uncertainties. The scattering nature of the
V S values estimated using different
V S–
N correlations was reduced significantly with the application of the methodology. Study results further clearly demonstrated the potential of the approach to eliminate various uncertainties involved in the estimation of
V S30 using general and soil-specific correlations.
