Soil liquefaction is the most undermodeled risk
in global infrastructure

Soil liquefaction alone caused $50B+ in losses in a single earthquake sequence. We make it modelable: site by site for engineers, portfolio-wide for insurers.

Case history search

Input your site parameters and retrieve the closest matching case histories from 8,634 real-world CPT and SPT records across 50+ earthquake events.

Side-by-side comparison

Compare multiple case histories on a single screen. Identify analogous site conditions to inform liquefaction probability for new assessments.

API access

Integrate NGL data into your GIS or risk modeling workflows via REST API. Submit a JSON payload of site parameters and receive ranked matches with similarity scores and AI-generated assessment in a single response.

Who it is for

Built for two audiences

The same case-history-grounded engine, accessed two ways.

For Geotechnical Engineers

Site-specific hazard, defensible by design

  • Query 8,634 verified case histories with your CPT and SPT parameters.
  • Get AI engineering analysis with CSR, CRR, and factor of safety reasoning attached.
  • Export to your reporting workflow. No proprietary lock-in.

For Insurers and Cat Modelers

Liquefaction signal for portfolio risk

  • Score liquefaction susceptibility across thousands of insured locations via API.
  • Plug a missing peril into your existing earthquake cat model. Liquefaction is currently treated as a damage multiplier, not a modeled hazard.
  • Calibrated against real loss events including Canterbury, Tohoku, and Chi-Chi.

Methodology

How GeoLiquefy works

Trained on real earthquake data

Our models are built on case histories from Tohoku, Christchurch, Chi-Chi, and Niigata. Not synthetic data. Every prediction traces back to physical ground truth.

Fits your existing process

Export results to your reporting workflow, query via API, or use the web interface for exploratory analysis. No proprietary lock-in.

Engineering-readable explanations

Every prediction includes step-by-step reasoning: CSR, CRR, factor of safety. Review and sign off on the methodology, not just the number.

Why Now?

Major earthquake frequency is rising as urban infrastructure density grows. The exposure window is narrowing.

Seismic losses from liquefaction exceeded $50B in the 2010-2011 Canterbury earthquake sequence alone. Infrastructure is being built at planetary scale without adequate tools for ground failure prediction. GeoLiquefy changes that.

Enterprise

Working on a large-scale geohazard risk assessment?

We run structured pilots with three groups: geotechnical consulting firms looking to scale review, reinsurance and cat modeling teams adding a liquefaction layer to portfolio risk, and government infrastructure agencies assessing exposure across critical assets. Every pilot includes platform access, API credentials, and direct researcher support from our Cal Poly collaboration.
