Kankossa fire, October 2026 Kankossa

Dying down · last detection 27 Oct 2026, 02:58 UTC

The fire started on 25 October 2026 in Kankossa, Mauritania, and satellites saw it burning for 3 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 1,937 hectares from heat detections, spread across a single municipality.

It is the 20th largest in Assaba since 2016 (of 45 with a page). Number 15 in Mauritania in 2026, of 33.

The power measured by the satellite is low (10.9 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Compare with…

Is it still active?

No detections since 27 Oct 2026, 02:58 UTC. That usually means no flame is visible from space any more, although hotspots may remain. Satellites pass a few times a day and cloud or smoke can hide the fire: a lack of detections is not an official extinction. Each country’s emergency service declares a fire contained or out.

It had gone 5 days without rain (1 mm or more) when it started.

This area had burned before

95% of the perimeter overlaps earlier fires recorded since 2016: 1,808 ha in 2023, 235 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 1,838 ha that had burned before.

How big is it?

It burned the equivalent of 1.2% of the area of London (19 km² against 1,583 km²).

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.

Frequently asked questions

How long did the Kankossa fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 25 October 2026 to 27 October 2026 (3 days). The perimeter dates it from 25 October 2026 to 26 October 2026.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 1,937 hectares (19.4 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Kankossa (1,867 ha, 0.2 %).
Is the Kankossa fire still active?
No fire detections since 27 Oct 2026, 02:58 UTC. A lack of detections is not an official extinction.
What was the weather like?
During the fire the temperature reached 39.7 °C, humidity dropped to 13 % and gusts hit 42 km/h. The fire danger index (FWI) reached 43, class Very high.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Mauritania (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.
  • Dates adjusted with the VIIRS detections inside the perimeter, which said 25 October 2026 to 26 October 2026. 31 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.

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 3.0 Intergovernmental Organisations (CC BY 3.0 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.
