Liquefaction Opportunity Mapping via Seismic Wave Energy

Abstract

An empirical, energy-based methodology for liquefaction hazard assessment and microzonation mapping is presented. The approach is probabilistic, considers the uncertainty in the liquefaction criterion, and is applicable to most earthquake-induced liquefaction analyses. The examples illustrated are for water-saturated sands at level ground. The energy of ground shaking is estimated from the Fourier amplitude spectra of the incident waves. The susceptible materials are characterized only by their corrected standard penetration test value
