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 2945 recorded within 20 km of this point since 12 February 2024 — 62 others scored the same. The last comparable one was on 29 August 2026.
What the source measured
NASA FIRMS (VIIRS) reported 27 fire pixels with a combined fire radiative power of 90 MW, at nominal confidence, 2 km from West Mifflin.
The 27 pixels cover about 3.8 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 375,774 people live within 35 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 39 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.
