Following and during the 2019 Ridgecrest Earthquake Sequence (July 4 M6.5 event and July 5 M7.1 event), the Geotechnical Extreme Events Reconnaissance (GEER) Association conducted reconnaissance in areas with extensive surface manifestation of liquefaction at Searles Lake, near Trona and Argus, CA (GEER 2019, Zimmaro et al. 2020).

In this study, nonlinear deformation analyses (NDA) and equivalent-static analyses (ESA) approaches were evaluated for a model bridge embankment that was underlain by a non-liquefiable crust layer, a liquefiable medium dense sand layer, and a non-liquefiable deep dense sand layer.
