Version 1.0 of the New Zealand Landslide Dam Database (NZLDD) has been collated to investigate dam formation, longevity, and stability. The database includes mapping, and/or remapping of 1036 dams, including those generated by the 2016 Kaikōura Earthquake. The NZLDD represents a significant increase in catalogued landslide dams—almost doubling the existing number of known and studied […]
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 […]
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 […]
Over the course of EILD project, several aerial photo and Lidar surveys were commissioned, and Digital Surface Models (DSM) generated. These data were used to map landslides that resulted from the 2016 M7.8 Kaikoura Earthquake and subsequent slides initiated by rainfall, as well as tracking and measuring landscape changes as mobilised debris cascades through catchments. […]
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 […]
The EILD webmap (below) displays spatial data captured or derived from the project as it becomes available. Some data can be downloaded from the links provided Currently the map has: Earthquake-induced landslides (points only) generated by the M7.8 M 2016 Kaikoura Earthquake Earthquake-induced forecast (probability) maps for 100-, 250-, 500- and 1000-year return period earthquake […]
The Version 2.0 inventory contains nearly 30,000 landslides. The data contains all landslides from Version 1.0, plus additional landslides mapped from the high-resolution aerial photographs. The Version 2.0 inventory is published as points that represent the centroids of the mapped landslide source area. Version 2.0 data is available in both CSV format and in GIS Shapefile format, projected in the NZGD 2000 New Zealand Transverse Mercator coordinate system.
The dataset presented here is a compilation a global dataset of over 1100 back-analysed landslides from academic papers and reports where these parameters are reported. The data is presented as csv. files containing information on the landslide location, reference source, volume and all available empirical runout data.
