Abstract:	This paper is a follow-up to a previous paper on the subject of liquefaction potential index (LPI), a parameter that is often used to characterize the potential for surface manifestation of liquefaction at a given site subjected to a given shaking level (represented by a pair of peak ground surface acceleration a(max) and moment magnitude M-w). In the previous paper by Juang and his coworkers, the LPI was re-calibrated for a piezocone penetration test (CM) model, and a simplified model based on LPI was created for computing the conditional probability of surface manifestation of liquefaction (P-G). In this paper, the model for this conditional probability Pc is extended into a complete framework for assessing the probability of surface manifestation of liquefaction in a given exposure time at a given site subjected to all possible ground motions at all seismic hazard levels. This new framework is formulated and demonstrated with an example site in 10 different seismic regions in the United States. (C) 2008 Elsevier B.V. All rights reserved.
