Recorded by satellite 170 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.
No stronger detection stands among the 8 recorded within 20 km of this point since 11 March 2026 — 2 others scored the same. Another comparable one was recorded here earlier the same day. 3 more were recorded here in the fortnight before it.
What the source measured
NASA FIRMS (VIIRS) reported 75 fire pixels with a combined fire radiative power of 539 MW, at nominal confidence, 21 km from Wichian Buri.
The 75 pixels cover about 10.5 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 31,423 people live within 50 km of this point.

How we know
One source: NASA FIRMS (VIIRS). Not yet confirmed by a second, independent source.
Our own score for this event is 66 out of 100, at 68 % confidence.
The score is ours, computed from intensity, exposed population and local history — not the source’s.
Computed under scoring rules v1. Rows carrying other versions were judged by different rules and are not directly comparable.
Under rules v1–v3, "critical" for a wildfire measured only the radiative power the satellite saw, not the people near it; since v4 (1 September 2026) it also requires exposed population. This page keeps the word it was published with.

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.
