Recorded by satellite today.
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 10 recorded within 20 km of this point since 30 August 2026 — one other scored the same. The last comparable one was on 1 September 2026.
What the source measured
NASA FIRMS (VIIRS) reported 122 fire pixels with a combined fire radiative power of 1276 MW, at high confidence, 45 km from Boca do Acre.
The 122 pixels cover about 17.1 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 3,538 people live within 50 km of this point.
This is the highest radiative power we have recorded at this point, over 85 readings since 2 September 2026 — the previous range was 1,274 MW to 1,276 MW.

How we know
One source: NASA FIRMS (VIIRS). Not yet confirmed by a second, independent source.
Our own score for this event is 50 out of 100, at 74 % confidence.
The score is ours, computed from intensity, exposed population and local history — not the source’s.
Computed under scoring rules v4. 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.
