Description

Liquefaction potential of Tezpur University has been assessed under hypothetical earthquake events using simplified method. The anticipated earthquake magnitude and its peak ground acceleration are assumed based on geophysical hazard study of the region. Seismic hazard analysis parameters are evaluated in terms of cyclic stress ratio (CSR) and cyclic resistance ratio (CRR). An earthquake of magnitude 6.5 with peak ground accelerations of 0.2g and 0.3g are considered in this analysis. Under the assumed earthquake event, the severity index of the site is found to be low to high as per susceptibility index of liquefaction hazard. Some mitigation measures are also recommended and to be practiced prior to construction.
