- NSHM is a model that calculates the likelihood and strength of earthquake shaking that might occur at any given site in Aotearoa New Zealand. The model is used by government and industry bodies alike to manage safety risks, improve national resilience, and help minimise the economic impact of seismic events.

Mar 9, 2022 · Earthquake hazard map showing peak ground accelerations having a 2 percent probability of being exceeded in 50 years, for a firm rock site. The map is based on the USGS models for the conterminous U.S. (2023), Hawaii (2021), and Alaska (2023).
The NSHM presents a range of maps, hazard curves and reports that can be used to provide a forecast of the earthquake shaking expected over, for example, the next 10, 50 or 100 years at a range of probability levels.
the national seismic hazard maps for the UK. This is to take account of advances in seismic hazard methodology since the last seismic hazard maps were developed by Musson and Sargeant (2007) and present the results in a format that will be compatible with the future Eurocode 8 revisions.

Abstract. We present updated seismic hazard maps for the United Kingdom (UK) intended for use with the National Annex for the revised edition of Eurocode 8. The last national maps for the UK were produced by Musson and Sargeant (Eurocode 8 seismic hazard zoning maps for the UK.
Hazards vary throughout the country, based on the geography and ground conditions, and the frequency and types of earthquakes that might occur in each location. The model presents data in the form of hazard curves, rupture sets, maps, and reports – and you can print, download spreadsheets, and share links from the model.
Mar 9, 2022 · What are the USGS National Seismic Hazard Maps? 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.
Testing the NSHM: The science is internationally peer reviewed by a large panel of experts, and we test the forecasts against past earthquakes, long term data sets and global science. This process and our advanced understanding of how earthquakes work ensures that we are using the best available science.
