Recorded by satellite yesterday.
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.
No stronger detection stands among the 6 recorded within 20 km of this point since 11 August 2026 — 3 others scored the same. Another comparable one was recorded here earlier the same day.
What the source measured
NASA FIRMS (VIIRS) reported 12 fire pixels with a combined fire radiative power of 227 MW, at nominal confidence, 170 km from Atalaia do Norte.
The 12 pixels cover about 1.7 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.

How we know
One source: NASA FIRMS (VIIRS). Not yet confirmed by a second, independent source.
Our own score for this event is 27 out of 100, at 54 % confidence.
The score is ours, computed from intensity, exposed population and local history — not the source’s.
Computed under scoring rules v2. Rows carrying other versions were judged by different rules and are not directly comparable.

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.
