Out · last detection 24 Sept 2025, 12:49 UTC

The fire started on 29 August 2025 in Kazungula, Zambia, and satellites saw it burning for 27 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 5,743 hectares from heat detections, spread across a single municipality.

It is the 16th largest in Southern since 2016 (of 59 with a page). Number 88 in Zambia in 2025, of 271.

It had gone more than two months without rain (1 mm or more) when it started.

This area had burned before

90% of the perimeter overlaps earlier fires recorded since 2016: 801 ha in 2016, 247 ha in 2017, 2,053 ha in 2018, 2,482 ha in 2019, 3,454 ha in 2020. Part of it burned more than once, so the yearly figures add up to more than the 5,183 ha that had burned before.

How big is it?

Burnt area inside each municipality, from crossing the GWIS perimeter with administrative boundaries. The distance runs from the point marking the centre of each area to the nearest fire: staying a kilometre away does not mean it reached the houses.

Inside the perimeter there was no noticeable built-up land and almost nobody lived there (GHSL 2025, satellite-based estimate).

This is an estimate on 100 m cells, made from satellite imagery and census data: it does not mean that homes burned or that anyone was harmed. The perimeter also contains land that never burned. The GHSL 2025 epoch is a projection made from 2020 and earlier data.

Frequently asked questions

How long did the Kazungula fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 29 August 2025 to 24 September 2025 (27 days). The perimeter dates it from 30 August 2025 to 23 September 2025.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 5,743 hectares (57.4 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Kazungula (5,765 ha, 0.3 %).
What was the weather like?
During the fire the temperature reached 37.0 °C, humidity dropped to 8 % and gusts hit 50 km/h. The fire danger index (FWI) reached 68, class Extreme.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Zambia (geoBoundaries). It is not an official report.

Where to verify it

A satellite detection is not an official report. Final figures and the fire’s status are published by each country’s emergency service.

Does something look wrong on this page?

This page is built from satellite data and official records, and it sometimes gets things wrong: the wrong dates, the wrong town, two fires merged into one, or something that was not a wildfire at all. If you know this fire first-hand (you live nearby, saw it, fought it or reported on it), tell us what really happened and we will check it.

How we know this
  • Perimeter: GWIS (Copernicus), rebuilt from heat detections rather than mapped on imagery.
  • Dates adjusted with the VIIRS detections inside the perimeter, which said 30 August 2025 to 23 September 2025. 147 Suomi-NPP VIIRS detections on those dates.
  • We have not matched this page with any official record.
  • Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.
  • Built-up area and population come from the JRC Global Human Settlement Layer (epoch 2025, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.

Where this data comes from

The perimeter comes from the Copernicus Global Wildfire Information System (GWIS), which rebuilds it from MODIS and VIIRS heat detections and publishes it under CC BY 4.0. It is not measured on imagery as in Europe, so it is an estimate. Heat detections come from the VIIRS sensors aboard Suomi-NPP and NOAA-20, distributed by NASA FIRMS at 375 m resolution. Municipal boundaries come from geoBoundaries ADM2 (Creative Commons Attribution 4.0 (CC BY 4.0)). The area per municipality is computed by WorldFires by crossing the perimeter with those boundaries, so it may differ from each country’s official figure.
