The earthquake-induced landslide (EIL) probability calculated with the EIL Forecast Tool V2.1 (version 2.1), using Peak Ground Acceleration (PGA) on Soil Class B for the 500 year mean return period. The EIL probability has been calculated at 32 m resolution, and then aggregated to 256 m and 512 m using the maximum option, for better display at smaller scales. The grid covers the areas with probabilities in the upper quartile. The quartiles were derived using an EIL probability grid developed without the earthquake PGA variable included in the model. The upper quartile is defined by probabilities greater than 0.000926. The PGA input (earthquake shaking data) used in the EIL Forecast Tool V2.1 has been obtained from the GNS Science's National Seismic Hazard Model (NSHM, 2010). The common V2.1 tool inputs (static data) have been derived from the NZ 8m Digital Elevation Model (LINZ, 2012) and the 1:1 250 000 Geological Map of New Zealand (2nd edition, 2018).

Earthquake-induced landscape dynamics (EILD) is an MBIE Endeavour programme led by GNS Science in association with experts from leading landslide research institutions in New Zealand and a suite of international experts. One of the programme aims is to quantify landslide activation thresholds and forecast landslide severity at different magnitudes of ground shaking, by studying landslides caused by the 2016 Kaikōura earthquake. It also seeks to develop a framework and tools to allow people to manage the risk to life, property and infrastructure from future earthquake-induced landslides, both in Aotearoa New Zealand and internationally.
