National Seismic Hazard Model U S Geological Survey The usgs provides seismic hazard maps for the u.s. and its territories based on earthquake sources, faulting, and ground shaking. the maps are updated periodically and used for building codes, insurance, and risk assessment. Ground shaking is the most powerful predictor of damage from an earthquake. the u.s. geological survey (usgs) national seismic hazard map shows the strength of ground shaking that has a 1 in 50 chance of being exceeded in a particular place in the lower 48 states over a period of 50 years. these maps are used in determining building seismic codes, insurance rates, and other public decisions.
What Happened To Seismic Zones Find out how earthquake hazards vary across the united states and what levels of shaking they can cause. the maps show seismic design categories (sdcs) that reflect the likelihood of experiencing different intensities of shaking. 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. The national seismic hazard maps are used by the insurance industry to set earthquake insurance premiums, by reinsurance companies to evaluate their risk to major disasters, by government officials and land use managers, and by private companies worried about the exposure of facilities and supply chains to natural hazards. A new map shows the probability of damaging earthquakes in the u.s. over the next 100 years. the map reflects updated data, models and faults, and reveals the increased hazard in some cities and regions.
