Recorded by satellite 49 days ago.
A thermal anomaly is a snapshot of one satellite pass, not a record of a fire’s life: we cannot say whether it kept burning after that pass.
It is the 3rd strongest of the 28 detections recorded within 20 km of this point since 9 March 2026. The last comparable one was on 4 July 2026. One more was recorded here in the fortnight before it.
What the source measured
NASA FIRMS (VIIRS) reported 23 fire pixels with a combined fire radiative power of 263 MW, at nominal confidence, 25 km from Aldeias Altas.
The 23 pixels cover about 3.2 km² — that is the footprint of the detection grid at 375 m resolution, not an estimate of how much land burned.
FIRMS does not report burned area, and neither do we.
An estimated 21,422 people live within 35 km of this point.

Safety Information
If a wildfire is approaching: follow evacuation orders immediately. Do not wait to see the fire. Close all windows and doors, remove combustible materials from around your home, and have an emergency go-bag ready. Air quality can deteriorate rapidly even at distance from the fire front — monitor local air quality advisories.
