   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.

   Dec 29, 2023 · The numbers labeled on the plot correspond to the 5th and 95th fractile ground motions with a 2% and 10% in 50-year probability of exceedance. The mean (2023 NSHM for CONUS and 2021 NSHM for Hawaii) and previous mean (2018 NSHM for CONUS and 2001 NSHM for Hawaii) are also shown. AFE: annual frequency of exceedance.
