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.

Subduction Zone Science
Subduction Zone Science
The most powerful earthquakes, tsunamis, landslides, and volcanic eruptions occur in subduction zones, where two plates collide and one is thrust beneath another.

Preliminary geology of the North Meadow Creek Area, Tobacco Root Mountains, southwest Montana: The North Meadow Creek Fault Preliminary geology of the North Meadow Creek Area, Tobacco Root Mountains, southwest Montana: The North Meadow Creek Fault
This report documents a previously unmapped fault, informally referred to herein as the North Meadow Creek fault, on the east flank of the Tobacco Mountains of southwestern Montana. This fault has an apparently long and complex history, including Quaternary offset of an older alluvial terrace, offset of a debris flow of presumed Pleistocene age, offset of rhyolite lava flows of presumed...
Moment magnitude for small earthquakes in the Delaware basin of west Texas and southeast New Mexico, USA Moment magnitude for small earthquakes in the Delaware basin of west Texas and southeast New Mexico, USA
The Delaware Basin region of west Texas and southeast New Mexico has become one of the most prolific regions of seismic activity in the continental United States due to widespread hydraulic fracturing and wastewater disposal injection. In response to the increased number of earthquakes in this region, rapid and accurate characterization of earthquake sources is necessary to understand...
Dynamic coupling between faulting, rifting and magmatism during 2021-2025 unrest on Reykjanes Peninsula, Iceland Dynamic coupling between faulting, rifting and magmatism during 2021-2025 unrest on Reykjanes Peninsula, Iceland
Interactions among faulting, earthquakes, and eruptions are fundamental to plate tectonics and hazard forecasting yet rarely observed along mid-ocean ridges. On Iceland's Reykjanes Peninsula, seismotectonic–volcanic unrest resumed after nearly 800-year hiatus, providing an opportunity to observe these interactions during 2021–2025 activity. By integrating high-resolution seismicity...

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...
American Samoa Mapping Project
USGS scientists are leading a sampling effort to the Samoa Basin, offshore of American Samoa. This work is part of an interagency-supported three-month hydrograph survey project led by NOAA and in partnership with BOEM.
Mapping the grid: The United States Magnetotelluric Array
The United States has been mapped from space to the ground across its surface; however never from the perspective of the planet’s own electrical heartbeat. Over nearly two decades, the United States Magnetotelluric Array quietly marched across the country, station by station, building the first-ever electrical portrait of the crust and upper mantle beneath the contiguous U.S. An ambitious, multi...
