Wildfire near Mile 91

Sierra LeoneNASA FIRMS (VIIRS)

Recorded by satellite 167 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 3rd strongest of the 17 detections recorded within 20 km of this point since 9 March 2026. The last comparable one was on 12 March 2026. 3 more were recorded here in the fortnight before it.

What the source measured

NASA FIRMS (VIIRS) reported 21 fire pixels with a combined fire radiative power of 446 MW, at nominal confidence, 16 km from Mile 91.

The 21 pixels cover about 2.9 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 9,082 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 52 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.

Series begins 10 February 2026. Comparisons refer to that period only. Collection gap: 14-26 August 2026.
