About this wildfire map
This map uses NASA's Fire Information for Resource Management System (FIRMS), which publishes active-fire detections from the VIIRS and MODIS instruments aboard NASA and NOAA satellites. Each dot is a thermal “hotspot” where the sensor measured fire-level heat, usually within 3 hours of the satellite passing overhead. It shows where fires are actively burning — not fire perimeters or evacuation zones. For safety and evacuation information, always follow your local emergency services.
