The US National Seismic Hazard Model (NSHM) was updated in 2023 for all 50 states using
new science on seismicity, fault ruptures, ground motions, and probabilistic techniques to …

During 2017–2018, the National Seismic Hazard Model for the conterminous United States
was updated as follows:(1) an updated seismicity catalog was incorporated, which includes …

We update the ground-motion characterization for the 2023 National Seismic Hazard Model
(NSHM) for the conterminous United States. The update includes the use of new ground …

Deep sedimentary basins amplify long‐period shaking from seismic waves, increasing the
seismic hazard for cities sited on such basins. We perform 3‐D simulations of point source …

The US Geological Survey National Seismic Hazard Models (NSHMs) are used to calculate
earthquake ground-shaking intensities for design and rehabilitation of structures in the …

NGA-Sub data resources are organized into a relational database. We describe the Site
table within that database structure, which contains metadata for 6502 stations that have …

We develop basin-depth-scaling models (ie “basin terms”) from the long-period (T≥ 2 s)
simulated ground motions of the Southern California Earthquake Center (SCEC) …

Studies of recorded ground motions and simulations have shown that deep sedimentary
basins can greatly increase the intensity of earthquake ground motions within a period …

We explore the response of ground motions to topography during large crustal fault
earthquakes by simulating several magnitude 6.5–7.0 rupture scenarios on the Seattle fault …

While soil liquefaction is common in earthquakes, the case-history data required to train and
test state-of-practice prediction models remains comparatively scarce, owing to the breadth …
