Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake and Water and information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted. For more information, please see www.doi.gov/shutdown

We carry out a wide range of wildfire-related science activities that span multiple USGS mission areas, including landscape ecology studies, geospatial support for fire response, burned area hydrology, and post-fire debris flow warnings.
Our satellite remote sensing research and applications are essential for providing required data for mapping fire fuels, assessing fire effects, monitoring fire danger, and measuring progress in implementing the National Fire Plan. Land management agencies, scientific communities, and citizenry affected by wildland fires can benefit from our work.
MTBS is a multi-year project designed to map the burn severity and perimeters of fire across all lands of the United States for the period spanning 1984 through 2010. The data generated by MTBS will be used to identify national trends in burn severity and evaluate the effectiveness of the National Fire Plan and Healthy Forest Restoration Act.
Post-fire landslides are particularly hazardous because they can occur with little warning, can exert great force on objects in their paths, can strip vegetation, block drainage ways, damage structures, and endanger human life. Our focus is to develop tools and methods for the prediction of post-wildfire landslide activity and hazard delineation.
Ecosystems throughout the western U.S. are often dependent on a particular fire regime to reduce hazardous fuels and rejuvenate forests or even guide evolution of plant life and regulate ecological communities. Today fire’s role is more complicated. For example, fire can favor invasive plants and these invaders may, in turn, alter the fire regime.
Organisms have different abilities to adapt to disturbances. Some disturbances can be catastrophic to one species and inconsequential to another. Our Forest and Rangeland Ecosystem Science Center (FRESC) scientists are studying the effects of disturbances on species, biogeochemistry, water quality, habitat connectivity and landscape patterns.

We conduct post-fire debris-flow hazard assessments for select fires in the Western U.S. We use geospatial data related to basin morphometry, burn severity, soil properties, and rainfall characteristics to estimate the probability and volume of debris flows that may occur in response to a design storm.
After a month, the wildfires of Southern California are nearly contained. Landsat 8 imagery shows the dramatic burn scars left behind.
At the USGS EROS Center, we study land change, operate the Landsat satellites, and maintain the longest, continuously acquired collection of images of the Earth's land surface.

Drone footage of a prescribed fire at Tall Timbers Research Station, Tallahassee, Florida (April 19, 2017).
In 2014, the Silverado Fire burned approximately 4 km^2 in Orange County, California. After the fire, the USGS installed an automated rain-triggered camera to monitor post-wildfire flooding and debris flow at the outlet of a small 0.6 km^2 basin within the burn area. This video shows the initial surge and peak flow triggered by an intense rainstorm on July 19, 2015. The...
Science for a Risky World: A USGS Plan for Risk Research and Applications – USGS publishes strategic plan for examining risk
USGS explores opportunities to advance its capabilities in risk assessment, mitigation, and communication in new strategic plan.
Learn About USGS Hazards Science and More About National Preparedness Month: The very nature of natural hazards means that they have the potential to impact a majority of Americans every year. USGS science provides part of the foundation for emergency preparedness whenever and wherever disaster strikes.
The public can now access information about active wildfires across the country using a smartphone.
Remotely-sensed data key to response in tracking danger in areas like Montecito
U.S. Geological Survey scientists and partners are taking technology to the next level, using unmanned aircraft systems (UAS), commonly called drones, to acquire both fire intensity and emissions data during prescribed burns.
September is National Preparedness Month, a time to highlight the resources available to help you and your loved ones stay as safe as possible.
A new interactive map and companion report from the U.S. Geological Survey allows residents living in and around New Mexico’s Jemez Mountains to see where they’re located in relation to postwildfire debris-flow hazards.
In what year did the United States experience the most acres burned from wildfires (on record)?
