New USGS-FEMA study highlights economic earthquake risk in the United States
Natural Hazards Mission Area
Every year in the United States, natural hazards threaten lives and livelihoods and result in billions of dollars in damage. We work with many partners to monitor, assess, and conduct targeted research on a wide range of natural hazards so that policymakers and the public have the understanding they need to enhance preparedness, response, and resilience.

Velocity-independent dry friction on mica: A realization of ideal Amontons-Coulomb friction Velocity-independent dry friction on mica: A realization of ideal Amontons-Coulomb friction
The Amontons-Coulomb friction law assumes that the frictional force between materials is independent of sliding velocity. However, as Coulomb noted, this is a rough approximation, and a second-order dependence of friction on the logarithm of sliding velocity is incorporated in a commonly used ‘rate- and state-dependent’ friction representation. Here we conduct shear experiments on mica...
Site-specific amplifications in Northwestern Turkiye: A generic approach Site-specific amplifications in Northwestern Turkiye: A generic approach
In this study, we derive generic site amplification functions applicable to Northwestern Türkiye and follow guidance on site classifications established by the United States National Earthquake Hazards Reduction Program (NEHRP). We employ the one-dimensional (1-D) equivalent linear ground response analysis method and focus on recordings from a select suite of free-field strong motion (SM...

Rainfall and Landslides in Northern California
A summary of recent and past landslides and debris flows caused by rainfall in northern California, and links to current shallow landslide monitoring.
2026 Venezuela Sequence Earthquake-Triggered Landslide Hazards
On Wednesday, June 24th, 2026, a pair of earthquakes of Magnitude 7.2 and Magnitude 7.5 occurred in northern Venezuela, west of Caracas. The U.S. Geological Survey (USGS) Ground Failure product estimated that landslides triggered by this earthquake would likely be significant in number and/or spatial extent. This landslide event page serves to communicate timely science information to our partners...
COAWST: A Coupled-Ocean-Atmosphere-Wave-Sediment Transport Modeling System
Understanding the processes responsible for coastal change is important for managing both our natural and economic coastal resources. Storms are one of the primary driving forces causing coastal change from a coupling of wave- and wind-driven flows. To better understand storm impacts and their effects on our coastlines, there is an international need to better predict storm paths and intensities...
