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.

Albuquerque Seismological Laboratory strategic vision Albuquerque Seismological Laboratory strategic vision
This circular presents a strategic outlook for the U.S. Geological Survey (USGS) Albuquerque Seismological Laboratory (ASL) for the next 10 years (2026–36). The ASL is a USGS field office in the Geological Hazards Science Center that operates portions of the Advanced National Seismic System and the Global Seismographic Network and focuses on fundamental research for instrumentation...
Constraining source and path effects of large magnitude earthquakes using ground motion simulations Constraining source and path effects of large magnitude earthquakes using ground motion simulations
The purpose of this study is to use ground‐motion simulations to investigate ways in which source and path effects for large‐magnitude earthquakes can be represented in nonergodic ground‐motion models (GMMs). To achieve this, we designed a ground‐motion study in the San Francisco Bay Area that includes earthquakes with a broad range of magnitudes distributed uniformly on a fault plane...

American Samoa Mapping Project
USGS scientists are leading a sampling effort to the Samoan 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.
Digital Shoreline Analysis System (DSAS)
Software for calculating positional boundary change over time The Digital Shoreline Analysis System (DSAS) version 6 is a standalone application that calculates shoreline or boundary change over time. The GIS of a user’s choice is used to prepare the data for DSAS. Like previous versions, DSAS v.6 enables a user to calculate rate-of-change statistics from multiple historical shoreline positions...
2025 M7.0 Hubbard Glacier Earthquake-Triggered Landslides and Snow Avalanches
A M7.0 oblique-slip earthquake initiated about 10 km below the Hubbard Glacier in the St. Elias Mountains about 88 km north of Yakutat, Alaska, at approximately 11:40am AKST (1:40pm YST) on December 6, 2025. 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 was confirmed...
