Recorded by satellite 19 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 4th strongest of the 14 detections recorded within 20 km of this point since 4 July 2026. The last comparable one was on 10 August 2026. One more was recorded here in the fortnight before it.
What the source measured
NASA FIRMS (VIIRS) reported 27 fire pixels with a combined fire radiative power of 206 MW, at nominal confidence, 8 km from Geita.
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 259,578 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 48 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.
