Recorded by satellite 20 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 14th strongest of the 64 detections recorded within 20 km of this point since 26 May 2026. The last comparable one was on 10 August 2026. 8 more were recorded here in the fortnight before it.
What the source measured
NASA FIRMS (VIIRS) reported 68 fire pixels with a combined fire radiative power of 486 MW, at high confidence, 41 km from Pemba.
The 68 pixels cover about 9.5 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 40,627 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 53 out of 100, at 84 % 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.
