Monitor wildfires with our interactive wildfires map (above). The flame icons represent wildfires currently active in the lower 48 states and Alaska. Hover over a given fire to see its name, and if you zoom in you’ll be able to see the outline of the area that’s burning — the so-called fire perimeter. If you click within the perimeter, a window pops up showing the fire’s size in acres, the amount by which the perimeter has grown or shrunk over the past 24 hours, the fraction of the fire that has been contained and other data. There’s also a link to an even more detailed report.
As temperatures warm and large parts of the U.S. become drier, wildfires are becoming more common and widespread — a trend likely to worsen thanks to climate change caused by human greenhouse gas emissions, as well as land use change and population growth. At the same time, population growth in and around lands that typically see wildfires may be responsible for increased losses from these blazes.
The interactive is based on data from the Geospatial Multi-Agency Coordination Group; the information is updated once a day from reports by fire managers on the scene, satellite imagery and GPS data, among other sources.
