   What is the national seismic hazard map (NSHM)?

   • The National Seismic Hazard Maps (NSHM) (and the hazard model from which they are derived) are first and foremost a suite of products aimed at improving earthquake-resilient construction in the United States. Engineers who construct buildings need to know how strongly a particular site might be shaken by earthquakes.

   What is the national seismic hazard model?

   • The National Seismic Hazard Model is a science based, agreed estimate of the likelihood and strength of earthquake shaking throughout New Zealand. It's a detailed model to help decision makers manage the risks, the losses due to earthquakes throughout New Zealand. The New Zealand Seismic Hazard Model is an amalgam of many models.

   What is seismic hazard map?

   • Seismic hazard map: Seismic hazard is the hazard associated with potential earthquakes in a particular area, and shows the relative hazards in different areas. Seismic source characterisation model: Mathematical representation of the spatial and temporal distribution of expected earthquakes within a magnitude range in a specific region.
