Right now
The most recent data we hold from NASA FIRMS (VIIRS) arrived 2 minutes ago, and this point is not in it. We record detections, not passes: an absence is not proof that nothing is there.
2 other detections within 20 km in the last 24 hours, the nearest 12 km from here.
Recorded by satellite 2 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 15th strongest of the 27 detections recorded within 20 km of this point since 30 August 2026. Another comparable one was recorded here earlier the same day.
What the source measured
NASA FIRMS (VIIRS) reported 29 fire pixels with a combined fire radiative power of 178 MW, at high confidence, 15 km from Porto Acre.
The 29 pixels cover about 4.1 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 9,576 people live within 35 km of this point.
Wind from ESE at 7 km/h at 00:00 UTC, according to MET Norway.

How we know
One source: NASA FIRMS (VIIRS). Not yet confirmed by a second, independent source.
Our own score for this event is 35 out of 100, at 74 % confidence.
The score is ours, computed from intensity, exposed population and local history — not the source’s.
Wind: MET Norway Locationforecast, CC BY 4.0.
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.
Series begins 8 March 2026. Comparisons refer to that period only. Collection gap: 14-26 August 2026.
