Liquefaction potential index calculations at cone penetration test sites in California
This data release provides tabulated liquefaction potential index (LPI) values
calculated for a standard set of magnitudes (M), peak ground accelerations (PGA), and
groundwater depths (GWD), as described in detail in Engler and others (2025). We use these
data to rapidly interpolate LPI values for any M-PGA-GWD combination. The LPI results are
computed at cone penetration test (CPT) sites in the San Francisco Bay Area (Holzer and
others, 2010). Additionally, the CPT sites are classified using surface geology maps
(Wentworth and others, 2023; Wills and others, 2015; Witter and others, 2006).
