Dori fire, 22 October 2026 Dori, Seytenga, Sampelga
The fire started on 22 October 2026 in Dori, Burkina Faso, and satellites saw it burning for 4 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,756 hectares from heat detections, spread across 3 municipalities.
It is the 71th largest in Liptako since 2016 (of 224 with a page). Number 39 in Burkina Faso in 2026, of 198.

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 7 days without rain (1 mm or more) when it started.
This area had burned before
52% of the perimeter overlaps earlier fires recorded since 2016: 1,216 ha in 2024, 1,184 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 1,436 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.
People and buildings inside the perimeter
GHSL 2025Inside the perimeter there were about 3.2 hectares of built-up land and about 600 residents (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 21 October 2026 the air beside the fire reached 49 µg/m³ of PM2.5. That day averaged 38: 2.5 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Dori fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 22 October 2026 to 25 October 2026 (4 days). The perimeter dates it from 22 October 2026 to 23 October 2026.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 2,756 hectares (27.6 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 3 municipalities: Dori (1,862 ha, 0.7 %); Seytenga (687 ha, 0.8 %); Sampelga (221 ha, 0.4 %).
- Is the Dori fire still active?
- No fire detections since 23 Oct 2026, 13:40 UTC. A lack of detections is not an official extinction.
- What was the weather like?
- During the fire the temperature reached 38.2 °C, humidity dropped to 12 % and gusts hit 41 km/h. The fire danger index (FWI) reached 46, class Very high.
- 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 adjusted with the VIIRS detections inside the perimeter, which said 22 October 2026 to 23 October 2026. 33 Suomi-NPP VIIRS detections on those dates.
- We have not matched this page with any official record.
- Weather: ECMWF IFS model, provisional until the ERA5 reanalysis arrives.
- 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 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.
