Are there wildfires in Brazil right now?

NASA's FIRMS satellites detected 19509 active fire hotspots in Brazil over the last 3 days, including 112 high-intensity fires. The map on this page shows their exact locations, updated hourly.

How does NASA detect wildfires?

NASA's VIIRS and MODIS instruments aboard the Suomi NPP, NOAA-20 and Terra/Aqua satellites detect thermal anomalies (heat signatures) from orbit. Each detection is a "hotspot" — a pixel where the sensor measured fire-level heat. Data is published within about 3 hours of the satellite overpass through the FIRMS system.

What does fire intensity (FRP) mean?

FRP (Fire Radiative Power, in megawatts) measures how much energy a fire is releasing. Higher FRP means a more intense fire. On this map, brighter red dots are higher-intensity detections.

Plus 1768 smaller heat detections — often agricultural burning rather than wildfire.

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.
