Tansarga fire, 17 November 2025 Tansarga
The fire started on 17 November 2025 in Tansarga, Burkina Faso, and satellites saw it burning for 5 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 1,102 hectares from heat detections, spread across a single municipality.
It is the 224th largest in Tapoa since 2016 (of 260 with a page). Number 532 in Burkina Faso in 2025, of 609.

Fire radiative power detected each day, in megawatts, and number of hotspots. The magenta bar marks the peak day.
This area had burned before
66% of the perimeter overlaps earlier fires recorded since 2016: 347 ha in 2016, 62 ha in 2019, 202 ha in 2021, 11 ha in 2022, 250 ha in 2023, 138 ha in 2024. Part of it burned more than once, so the yearly figures add up to more than the 728 ha that had burned before.

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.

The smoke
CAMS · CopernicusOn 16 November 2025 the air beside the fire reached 57 µg/m³ of PM2.5. That day averaged 47: 3.2 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Tansarga fire last?
- GWIS (Copernicus) dates it between 17 November 2025 and 21 November 2025: 5 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 1,102 hectares (11.0 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Tansarga (552 ha, 0.7 %).
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Burkina Faso (OCHA COD-AB). 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 from the perimeter: the VIIRS detections inside it did not change them. 31 Suomi-NPP VIIRS detections on those dates.
- We have not matched this page with any official record.
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 OCHA COD-AB (Institut Geographique Burkina (IGB)) (Creative Commons Attribution for Intergovernmental Organisations (CC BY-IGO)). 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.
