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.

CRESCENT earthquake dynamic rupture, earthquake cycle, and tsunami code verification platform CRESCENT earthquake dynamic rupture, earthquake cycle, and tsunami code verification platform
Physics-based simulations are critical for understanding natural hazards. The increasing complexity of numerical codes requires benchmark exercises to verify that different computational methods yield consistent results when solving the same governing equations. Here, we present an open-access web platform designed for the verification of earthquake dynamic rupture, seismic cycle, and...
Corundum discovered by SuperCam and the Perseverance rover at Jezero crater, Mars Corundum discovered by SuperCam and the Perseverance rover at Jezero crater, Mars
Mars is primarily composed of mafic mineral assemblages and their alteration products, but small, scattered rocks strewn across the landscape offer clues to greater petrological diversity. While traversing the Jezero crater rim, the Perseverance rover encountered several plagioclase-rich light-toned float rocks. SuperCam identified the distinctive signature of corundum (α-Al2O3) in these...
Simulation-based scenario ShakeMaps for large magnitude (MW6.5+) crustal earthquakes on the Seattle, Tacoma, and southern Whidbey Island faults, Washington, USA Simulation-based scenario ShakeMaps for large magnitude (MW6.5+) crustal earthquakes on the Seattle, Tacoma, and southern Whidbey Island faults, Washington, USA
Scenario ground‐motion maps based on empirical ground‐motion models (GMMs) provide a rapid and generally reliable means of estimating the amplitude and distribution of earthquake shaking. However, because GMMs are designed for broad applicability, they often rely on simplified representations of Earth structure, which can limit their accuracy in regions with complex source, path, and...

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...
