Massey, C.I.; Lukovic, B.; Huso, R.; Buxton, R.; Potter, S.H. 2021 Earthquake-induced landslide forecast tool for New Zealand: version 2.0. Lower Hutt, N.Z.: GNS Science. GNS Science report 2018/08. 77 p.; doi: 10.21420/G2TP9V
Abstract:
This report outlines a prototype earthquake-induced landslide forecast tool (Version 2.0) for New Zealand. This tool produces a model of landslide probability after a significant earthquake in near-real time – approximately 5–7 minutes after being triggered. The function of this tool is to provide rapid advisory information about the ‘intensity’ and likely location of landslides following a major earthquake in New Zealand. Ground shaking data recorded by the GeoNet strong motion instrument network is currently used as the input for the tool. Overall, the statistical models that underpin the tool provide a robust forecast of landslide probability at different levels of earthquake peak ground acceleration, the forecasts can be generated in the minutes after a major earthquake and can be used to help guide response efforts.
