摘要
The corrected 2010 New Zealand National Seismic Hazard Model has been adapted for use in the Global Earthquake Model's OpenQuake engine through an extensive benchmarking exercise with GNS Science's legacy Fortran code. Resolution of differences between the legacy code and OpenQuake result in hazard curve output comparisons with discrepancies of less than 3% nationally and remaining discrepancies highlight challenges faced when moving away from in-house legacy code. OpenQuake's multiple and varied computation options for both hazard and risk and OpenQuake's consistent, software-friendly output formats allow for exploration and development of innovative approaches to future seismic hazard and risk modeling in New Zealand. The end-to-end seismic hazard-to-risk capabilities already enabled by the inclusion of New Zealand seismic hazard, vulnerability, and building exposure models in OpenQuake have already had significant impact on post-disaster response to the 2016 Kaikoura earthquake.
