Probabilistic Approach of Liquefaction Assessment for Guwahati Based on Shear Wave Velocity Values
https://orcid.org/https://orcid.org/0000-0002-1549-9065
Guwahati is one of the fastest growing cities in the North East India. It is situated along the banks of river Brahmaputra and is classified into seismic zone V in the seismic zonation map of India. The high seismic hazard in North East India points to the fact that earthquake-induced liquefaction assessment for these regions is necessary. Due to the large number of uncertainties associated with the evaluation of soil liquefaction, probabilistic liquefaction assessment has gained significance. In this study, liquefaction potential is evaluated by following a sequence of steps which include the generation of an earthquake catalogue, identification of the seismic sources, developing probabilistic seismic hazard, and probabilistic assessment of liquefaction potential. The use of probabilistic methods in liquefaction potential evaluation will help in quantifying the uncertainties involved in seismic hazard and soil resistance in a better way. The spatial maps showing the variation of factor of safety against liquefaction for different return periods are developed based on the shear wave velocity values. These results will help in delineating regions with high liquefaction hazard in the city thereby facilitating risk mitigation activities.
