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 …

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 …

We develop semi-empirical ground motion models (GMMs) for peak ground acceleration,
peak ground velocity, and 5%-damped pseudo-spectral accelerations for periods from 0.01 …

We have produced a large set of broadband (0–10 Hz) synthetic seismograms for M w 9.0
earthquakes on the Cascadia megathrust by combining synthetic seismograms derived from …

The Cascadia subduction zone (CSZ) is an exceptional geologic environment for recording
evidence of land-level changes, tsunamis, and ground motion that reveals at least 19 great …

As ShakeAlert, the earthquake early warning system for the West Coast of the US, begins its
transition to operational public alerting, we explore how post-alert messaging might …

The coastal Pacific Northwest USA hosts thousands of deep-seated landslides. Historic
landslides have primarily been triggered by rainfall, but the region is also prone to large …

Rapid fault rupture information is important to estimate seismic ground motions and damage
in large earthquakes, and is, therefore, of great value for earthquake early warning (EEW) …

Advances in physics‐based earthquake simulations, utilizing high‐performance computing,
have been exploited to better understand the generation and characteristics of the high …

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 …
