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 […]

RoARS Tool

Introduction The Rockfall Activity Rate System (RoARS) provides an indication/forecast of the magnitude of rock/debris that could fall from a slope – of a given height, angle, and area – at different levels of earthquake shaking. These forecasts are derived from an empirical relationship between the volumes of rock that fell from the selected Port […]

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 […]

Landslides triggered by an earthquake require significant ground shaking (>0.2 PGA) triggered by larger earthquakes of magnitude (M) >5.0. The 2016 Kaikoura M7.8 earthquake, generated over 30,000 landslides causing significant damage to transport infrastructure, creating hazardous landslide dams, and depositing sediment into catchments that will impact rivers and infrastructure for decades to come.

Hazards posed by such events can be managed to a certain extent, reducing the risk. The Earthquake-induced Landscape Dynamics research programme has developed tools, guidance and case studies that can be utilised from Response through to Reduction, to increase resilience to such events. These are summarised and available from this Framework diagram. Click the links to explore the resources
