Kankossa fire, February 2026 Kankossa

Out · last detection 23 Feb 2026, 13:53 UTC

The fire started on 17 February 2026 in Kankossa, Mauritania, and satellites saw it burning for 7 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 4,758 hectares from heat detections, spread across a single municipality.

It is the 5th largest in Assaba since 2016 (of 44 with a page). Number 2 in Mauritania in 2026, of 30.

The power measured by the satellite is low (15.7 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

It had gone 39 days without rain (1 mm or more) when it started.

This area had burned before

57% of the perimeter overlaps earlier fires recorded since 2016: 3,494 ha in 2016, 886 ha in 2020, 9 ha in 2021, 1,601 ha in 2022, 1 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 2,728 ha that had burned before.

Frequently asked questions

How long did the Kankossa fire last?
GWIS (Copernicus) dates it between 17 February 2026 and 23 February 2026: 7 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 4,758 hectares (47.6 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Kankossa (4,552 ha, 0.4 %).
What was the weather like?
During the fire the temperature reached 38.7 °C, humidity dropped to 5 % and gusts hit 54 km/h. The fire danger index (FWI) reached 81, class Very extreme.
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.

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.

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.
