Landslide Planning Guidance

A tool for reducing landslide risk through land-use planning GNS Science has produced guidance for planners to reduce landslide risk through land-use planning. The guidance strongly emphasises the need to incorporate landslide risk early in the land-use planning decision-making process to avoid costly and potentially dangerous new developments that could pose a risk to the […]

Earthquake-induced landslide forecast tool

This tool provides rapid advisory information about the ‘intensity’ and likely location of landslides following a major earthquake in New Zealand. The tool produces a model of landslide probability after a significant earthquake in near-real time – approximately 7 minutes after being triggered. The tool is operational within the National Geohazard Monitoring Centre of GeoNet […]
