Wildfire near Vryheid

South AfricaNASA FIRMS (VIIRS)

Detected once by satellite, 36 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 16th strongest of the 46 detections recorded within 20 km of this point since 11 May 2026. The last comparable one was on 24 July 2026.

What the source measured

NASA FIRMS (VIIRS) reported 21 fire pixels with a combined fire radiative power of 136 MW, at nominal confidence, 24 km from Vryheid.

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 45,478 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.

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