Recorded by satellite 70 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 7th strongest of the 25 detections recorded within 20 km of this point since 7 May 2026. The last comparable one was on 13 June 2026. 4 more were recorded here in the fortnight before it.
What the source measured
NASA FIRMS (VIIRS) reported 2 fire pixels with a combined fire radiative power of 227 MW, at nominal confidence, 13 km from Formosa do Rio Preto.
The 2 pixels cover about 0.3 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 8,897 people live within 20 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.
