Wildfires near Westonaria

City of JohannesburgSouth AfricaNASA FIRMS (VIIRS)

Recorded by satellite 85 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 6th strongest of the 136 detections recorded within 20 km of this point since 10 May 2026. The last comparable one was on 7 June 2026. 24 more were recorded here in the fortnight before it.

What the source measured

NASA FIRMS (VIIRS) reported 107 fire pixels with a combined fire radiative power of 845 MW, at high confidence, 14 km from Westonaria.

The 107 pixels cover about 15.0 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 5,885,041 people live within 50 km of this point.

Wind from NNE at 13 km/h at 09:00 UTC, according to MET Norway.

How we know

One source: NASA FIRMS (VIIRS). Not yet confirmed by a second, independent source.

Our own score for this event is 84 out of 100, at 84 % confidence.

The score is ours, computed from intensity, exposed population and local history — not the source’s.

Wind: MET Norway Locationforecast, CC BY 4.0.

Computed under scoring rules v1. Rows carrying other versions were judged by different rules and are not directly comparable.

Under rules v1–v3, Critical for a wildfire measured only the radiative power the satellite saw, not the people near it; since v4 (1 September 2026) it also requires exposed population. This page keeps the word it was published with.

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 8 March 2026. Comparisons refer to that period only. Collection gap: 14-26 August 2026.
