Technical report: Automated Liquefaction Vulnerability Categories mapping

This report describes how Automated Liquefaction Vulnerability Categories (ALVC) maps were developed as part of the National Liquefaction Model. The ALVC maps are intended to support local councils and regional authorities in developing or updating LVC maps under the MBIE/MfE Guidance (2017).

The report outlines the methods, data inputs and outputs used to classify liquefaction vulnerability across New Zealand, and explains how the maps can support regional-scale planning and analysis. The report also highlights key limitations and the need for expert review and local refinement when applying the results.
