Tcholliré fire, 1 December 2023 Tcholliré
The fire started on 1 December 2023 in Tcholliré, Cameroon, and satellites saw it burning for 3 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 1,398 hectares from heat detections, spread across a single municipality.
It is the 784th largest in North since 2016 (of 1648 with a page). Number 129 in Cameroon in 2023, of 270.
The power measured by the satellite is low (26.3 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

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.
This area had burned before
20% of the perimeter overlaps earlier fires recorded since 2016: 12 ha in 2017, 117 ha in 2018, 100 ha in 2020, 104 ha in 2022. Part of it burned more than once, so the yearly figures add up to more than the 286 ha that had burned before.

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

The smoke
CAMS · CopernicusOn 29 November 2023 the air beside the fire reached 48 µg/m³ of PM2.5. That day averaged 38: 2.5 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Tcholliré fire last?
- GWIS (Copernicus) dates it between 1 December 2023 and 3 December 2023: 3 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 1,398 hectares (14.0 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Tcholliré (1,408 ha, 0.1 %).
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Cameroon (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.
Satellite cross-check
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. 19 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 geoBoundaries ADM3 (Open Data Commons Open Database License 1.0). 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.
