Ross Hartleb of LCI has co-authored a technical paper, “Paleoliquefaction Studies and the Evaluation of Seismic Hazard”, with Tish Tuttle (M. Tuttle & Associates), Lorraine Wolf (Auburn University), and Paul Mayne (Georgia Tech). The paper appears in Geosciences, an open-access journal from MDPI, and is available here.
This review paper presents background information on earthquake-induced liquefaction and resulting soft-sediment deformation features that may be preserved in the geologic record, best practices used in paleoliquefaction studies, and application of paleoliquefaction data in earthquake source characterization. The paper concludes with two examples of regional paleoliquefaction studies—in the Charleston seismic zone and the New Madrid seismic zone in the southeastern and central United States, respectively—that contributed to seismic source models used in earthquake hazard assessment.
