   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.

   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.

   • The main output from this work is a set of national seismic hazard maps (for return periods of 95, 475, 1100 and 2475 years) based on the new model that depict spectral acceleration (SA) at 0.2 s and 1.0 s for 5% damping, and for a single rock site condition (Vs30 = 800 m/s) across the study area.
