   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 minimum magnitude of a low seismicity hazard (NSHM)?

   • Recent NSHMs in low seismicity regions have a minimum magnitude between 4.3 and 4.5 Mw (Wiemer et al. 2016; Grünthal et al. 2018; Drouet et al. 2020). The SSC and GMC models used in the hazard computation are shown in Fig. 11.

   What is the 2023 NSHM hazard model?

   • The USGS has completed and released the 2023 updated hazard model for the 50 states. The 2023 NSHM includes recently updated ground motion models for subduction-zone faults (present in the Pacific Northwest and Alaska) as part of its updated national hazard assessment.

   How can NSHM be strengthened in low seismicity regions?

   • Although this challenge requires ongoing monitoring in low seismicity regions, a way to strengthen the NSHM is to focus on better capturing the uncertainties in every component of the hazard model such as considering alternative branches in the source model logic tree and quantifying the uncertainty in the earthquake parameters.
