Rainfall-induced landslide forecasting, rapid assessment and hindcasting

Ex-Tropical Cyclone Gabrielle triggered over 100,000 landslides across the North Island damaging houses, power lines, bridges, roads and creating dams across channels.  This is potentially the largest landslide-triggering event on record in Aotearoa. Our response required development of new landslide mapping and modelling approaches in order to collate the landslide data. This novel approach provides stakeholders with a timely and sufficient level of spatial and positional accuracy about landslide occurrence and severity – where landslides could occur, did occur and might occur again in the future.
