Jan 16, 2024 · The 2023 50-State Update of the U.S. National Seismic Hazard Model (NSHM) defines the potential for earthquake ground shaking for various probability levels across the conterminous United States, Alaska, and Hawaii and is applied in seismic provisions of building codes, insurance rate structures, risk assessments, and other public policy. Faults are more likely to rupture (more ready) where tectonic stress has built up over many years without an earthquake.
