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.

Characterizing Meteor Crater impact melts through geochemistry and textural analysis
The U.S. Geological Survey Astrogeology Science Center houses the Meteor Crater sample collection, an assemblage of over 2,500 meters of cuttings from 161 drill holes into Meteor Crater’s rim, flanks, and ejecta blanket. We have utilized this unique collection to study the composition and spatial distribution of impact-generated materials from within the ejecta blanket. Meteor Crater has...
Pediment formation and subsequent erosion in Gale crater: Clues to the climate history of Mars
Evidence of paleo-rivers, fans, deltas, lakes, and channel networks across Mars has prompted much debate about what climate conditions would permit the formation of these surface water derived features. Pediments, gently sloping erosional surfaces of low relief developed in bedrock, have also been identified on Mars. On Earth, these erosional landforms, often thought to be created by...
No magmatic driving force for Europan sea-floor volcanism
The internal ocean of Jupiter’s moon Europa is thought to be a prime candidate for hosting extraterrestrial life. Europa’s silicate interior may contribute to habitability via the generation of reactants through hydrothermal activity, serpentinization, or other geological processes occurring on or just below Europa’s seafloor. However, silicate melting is thought to occur at >100 km...

Southwest Fire Innovation Landscape Network: Advanced tools for fuel monitoring and assessment of wildfire risk
The USGS Southwest Biological Science Center is coordinating the Southwest Fire Innovation Landscape Network to prepare fire and natural resource managers for rapidly changing fire landscapes by conducting research and building science-management partnerships. The network develops advanced tools and technologies to assess fuel loads and the effectiveness of fuel treatments, understand wildfire...
USGS Fire Science Support for DOI Lands
The USGS Fire Science Support for DOI Lands project is a U.S. Geological Survey (USGS) effort to address key aspects of recent legislation concerning wildland fire on Department of the Interior (DOI) lands. The project was initiated in 2023, and work will continue through 2025. The project is comprised of four separate but interrelated tasks and is guided by the input of DOI bureau representatives...
