GeoLiquefy's methodology is built on published science, and its research activity is public. This page records it: where the methodology has been presented, the white paper behind it, and the India validation program.
“Beyond the Factor of Safety” (CalGeo, 2026) presented the methodology behind the Liquefaction Hazard Engine at CalGeo, the California geotechnical engineers' association conference.
Delivered an invited technical seminar on the methodology at Moody's, attended by roughly 145 people.
Tiwari, A., Moss, R. & Gupta, A.K. (2026). On why the factor of safety compresses a multidimensional problem into a single, false-precision number, and how matching a site to documented case histories in the NGL database restores the information that compression discards.
Download the Paper →GeoLiquefy is running an open research initiative to validate Boulanger & Idriss (2014) triggering against Indian SPT and CPT profiles with known liquefaction outcomes. This is research in progress, not a completed validation. We are not claiming Indian-specific calibration today.
See the methodology page for the full framing. If your organization holds SPT or CPT profiles with documented liquefaction outcomes and is willing to contribute them to this record, we would like to hear from you.
Contribute Data →Robb Moss, Professor of Civil and Environmental Engineering at Cal Poly and author of Moss et al. (2006), a CPT-based triggering model plotted as a reference curve in the Liquefaction Hazard Engine, serves on GeoLiquefy's advisory board. See the team page for the full advisory board.
