Wildfires can dramatically alter how water moves across the landscape. As a result, even modest rainstorms can trigger dangerous flash floods and debris flows in steep burned areas. In response, the USGS produces postfire debris-flow hazard assessments for recently burned areas. These hazard assessments estimate the likelihood, volume, and combined hazard of debris-flows in recently burned. This page describes an interactive map for viewing and filtering these assessments.
Postfire Debris-flow Hazard Assessment Dashboard
The above dashboard is an interactive map for viewing and filtering postfire debris-flow hazard assessments. Users can pan and zoom the map to view assessments in areas of interest. Users can also filter assessments by year, state, and fire event.
Although the dashboard is primarily intended for viewing assessments, users can also find data download links by clicking on an assessment and inspecting the pop-up summary window. More comprehensive data access methods can also be found on the data access page. Software developers can also find the code used to produce the hazard assessments on the software page.
