Wildfire Hazards


Programs L2 Landing Page

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.

Satellite Data Applications for Fire Science

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.

Monitoring Trends in Burn Severity (MTBS)

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-Wildfire Landslide Hazards

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.

Fire Ecology

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.

Change and Disturbances

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.

Emergency Assessment of Post-Fire Debris-Flow Hazards

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.

Image of the Week - Southern California Wildfires Update

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.

Post-wildfire Flood and Debris Flow: 2014 Silverado Fire

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

Living with Fire: Chaparral Removal

Southern California's fire ecology is unlike that of anywhere else in the United States. Fire control strategies developed for mountain forests don't have the same results here. So can science help uncover new answers to help Southern California communities manage and live with wildfires? This 10 minute film showcases ongoing USGS research supporting agencies on the
