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.
It is the 2nd strongest of the 14 detections recorded within 20 km of this point since 14 March 2026. Another comparable one was recorded here earlier the same day.
What the source measured
NASA FIRMS (VIIRS) reported 59 fire pixels with a combined fire radiative power of 1256 MW, at high confidence, 20 km from Semikarakorsk.
The 59 pixels cover about 8.3 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 132,877 people live within 50 km of this point.
This is the highest radiative power we have recorded at this point, over 14 readings since 1 September 2026 — the previous range was 1,255 MW to 1,256 MW.

How we know
One source: NASA FIRMS (VIIRS). Not yet confirmed by a second, independent source.
Our own score for this event is 64 out of 100, at 74 % 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.
