A new methodology is proposed for the geotechnical analysis of strength of
paleoseismic shaking using liquefaction effects. The proposed method provides
recommendations for selection of both individual and regionally located test sites,
techniques for validation of field data for use in back-analysis, and use of a recently
developed energy-based solution to back-calculate paleoearthquake magnitude and
strength of shaking. The proposed method allows investigators to assess the influence
of post-earthquake density change and aging. The proposed method also describes
how the back-calculations from individual sites should be integrated into a regional
assessment of paleoseismic parameters.
