Mpika fire, 1 September 2025 Mpika
The fire started on 1 September 2025 in Mpika, Zambia, and satellites saw it burning for 20 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 12,614 hectares from heat detections, spread across a single municipality.
It is the 73th largest in Muchinga since 2016 (of 516 with a page). Number 34 in Zambia in 2025, of 271.

Where it burned
How it evolved, day by day
Fire radiative power detected each day, in megawatts, and number of hotspots. The magenta bar marks the peak day.
The weather it burned in
It had gone more than two months without rain (1 mm or more) when it started.
This area had burned before
92% of the perimeter overlaps earlier fires recorded since 2016: 2,400 ha in 2016, 5,805 ha in 2017, 1,499 ha in 2018, 1,033 ha in 2019, 6,384 ha in 2020, 1,515 ha in 2021, 4,854 ha in 2022, 3,369 ha in 2023, 1,756 ha in 2024. Part of it burned more than once, so the yearly figures add up to more than the 11,663 ha that had burned before.

What happened to each town

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.
People and buildings inside the perimeter
GHSL 2025Inside 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.

The smoke
CAMS · CopernicusOn 3 September 2025 the air beside the fire reached 58 µg/m³ of PM2.5. That day averaged 34: 2.3 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Mpika fire last?
- GWIS (Copernicus) dates it between 1 September 2025 and 20 September 2025: 20 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 12,614 hectares (126.1 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Mpika (12,698 ha, 0.7 %).
- What was the weather like?
- During the fire the temperature reached 35.7 °C, humidity dropped to 16 % and gusts hit 38 km/h. The fire danger index (FWI) reached 49, 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. 327 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.
