- Abstract
Valleys containing Fluvial-lacustrine deposits with shallow groundwater are susceptible to seismic liquefaction. In fact, extensive liquefaction was observed in the Kathmandu Valley during earlier earthquakes. The factor of safety and liquefaction potential index (LPI) were calculated using the simplified procedure of liquefaction potential assessment for 143 standard penetration test (SPT) profiles, conducted in different surface geological units of the valley, based upon which, a liquefaction susceptibility map for Kathmandu Valley has been proposed. The result shows that 44.4% of the area in Kathmandu valley lies in very high risk, 28.36% in high risk, 21.53% in low risk, and 5.71% in very low risk of liquefaction hazard.
