Wildfire near Vryheid

South AfricaNASA FIRMS (VIIRS)

Detected once by satellite, 53 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 7th strongest of the 78 detections recorded within 20 km of this point since 21 May 2026. The last comparable one was on 7 July 2026.

What the source measured

NASA FIRMS (VIIRS) reported 81 fire pixels with a combined fire radiative power of 660 MW, at high confidence, 5 km from Vryheid.

The 81 pixels cover about 11.3 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 165,265 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 71 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.
