A team of earthquake geologists, seismologists, and engineering seis- mologists has collectively produced an update the national probabilistic seismic hazard (PSH) model for New Zealand (National Seismic Hazard Model, or NSHM). The new NSHM supersedes earlier published in 2002 used as basis Loadings Standard numerous other end-user applica- tions. incorporates a fault source that been updated with over 200 onshore offshore sources utilizes Zealand-based international scaling relationships parameterization faults. dis- tributed seismicity also to include post-1997 data, regionalization, improved methodology calculation parameters. Probabilistic maps from show similar pattern at scale, but there are some significant reductions increases regional scale. national-scale differences between appear less than those seen much models, indicating degree consis- tency achieved estimates, least return periods 475 years greater.
