Recorded by satellite 24 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 10th strongest of the 224 detections recorded within 20 km of this point since 3 May 2024. Another comparable one was recorded here earlier the same day. 24 more were recorded here in the fortnight before it.
What the source measured
NASA FIRMS (VIIRS) reported 25 fire pixels with a combined fire radiative power of 697 MW, at high confidence, 172 km from Rexburg.
The 25 pixels cover about 3.5 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.

How we know
One source: NASA FIRMS (VIIRS). Not yet confirmed by a second, independent source.
Our own score for this event is 54 out of 100, at 64 % confidence.
The score is ours, computed from intensity, exposed population and local history — not the source’s.

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.
