Out · last detection 2 Oct 2025, 12:01 UTC

The fire started on 2 September 2025 in Mafinga, Zambia, and satellites saw it burning for 30 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 15,016 hectares from heat detections, spread across a single municipality.

It is the 55th largest in Muchinga since 2016 (of 516 with a page). Number 29 in Zambia in 2025, of 271.

It had gone 43 days without rain (1 mm or more) when it started. Rain came after the fire: 5.9 mm on 2 Oct.

This area had burned before

89% of the perimeter overlaps earlier fires recorded since 2016: 7,695 ha in 2016, 4,733 ha in 2017, 4,345 ha in 2018, 1,360 ha in 2019, 5,722 ha in 2020, 3,451 ha in 2021, 4,977 ha in 2022, 4,041 ha in 2023, 1,472 ha in 2024. Part of it burned more than once, so the yearly figures add up to more than the 13,311 ha that had burned before.

Frequently asked questions

How long did the Mafinga fire last?
GWIS (Copernicus) dates it between 2 September 2025 and 1 October 2025: 30 days between the first and last heat detection of the perimeter.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 15,016 hectares (150.2 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Mafinga (15,119 ha, 3.6 %).
What was the weather like?
During the fire the temperature reached 33.8 °C, humidity dropped to 14 % and gusts hit 47 km/h. The fire danger index (FWI) reached 44, class Very high.
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; 2 polygons grouped in this page.
  • Dates from the perimeter: the VIIRS detections inside it did not change them. 491 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.

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.
