DRAFT: Supplementary Data Release for Framework for Mapping Liquefaction Hazard-Targeted Design Ground Motions

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 07, 2026 | Last Modified: 2024-06-25T00:00:00Z
These data are supplementary to the journal article Makdisi, A.J., Kramer, S.L. (In-Review). Framework for Mapping Liquefaction Hazard-Targeted Design Ground Motions (doi to be updated on full publication). This dataset includes tabular data summarizing mean and standard deviation liquefaction factor of safety (FSL) ratios, effective FSL return periods, and example reference liquefaction-targeted design peak ground acceleration parameters (PGAL) for 96 geographic locations throughout the conterminous United States. These data were used to generate Figure 4, Figure 5, Figure 7, and Table 2 and Table 5 in the article. Notes: - Procedures for calculating PGAL and FSL are detailed in Section 4.1 (Equations 2 and 3 and Figure 6) of the corresponding journal article. - Mean magnitude Mw was calculated using the procedures outlined in the Appendix (Equation A.4a and A.4b) of the corresponding journal article. - Blank entries in the "SummaryData_Tr*.csv" files should be interpreted as NaN, and correspond to study locations where the computed liquefaction factors of safety (FSL) were above 3.0 for all soil conditions considered (i.e., liquefaction hazard was considered sufficiently low at these sites)
