“…The approach that has gained wide acceptance within the framework of urban planning is to establish microzonation maps with respect to liquefaction susceptibility to mitigate possible earthquake damage related to liquefaction (Kavazanjian et al, 1985;Todorovska, 1998;Ansal and Tönük, 2005).

“…This paper illustrates the application of an energy-based methodology to microzonation mapping of liquefaction opportunity on level ground. The methodologies for opportunity mapping applied so far (Youd 1991) are based on: (1) magnitude-distance relation (Yegian and Whitman 1978;Youd and Perkins 1978;Tinsley et al 1985); (2) magnitude-maximum acceleration relations (Atkinson et al 1984;Kavazanjian et al 1985); and (3) liquefaction severity index (Youd and Perkins 1987). The first two types consider only the initiation of liquefaction, whereas the third also considers the consequences.…”

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 N and overburden pressure 0. Illustrative microzonation maps of liquefaction opportunity are shown for the Los Angeles metropolitan area. Two types of maps are presented, one showing the average return period of liquefaction occurrence (for given N and 0), and another one showing distribution of N with equal probability to liquefy during 50 years exposure (for given 0). An advantage of the method is that the result is given directly in terms of in situ albeit simple soil characteristics rather than in terms of laboratory tests and peak acceleration. Possible applications of the computed opportunity maps are discussed.
