Ghabou fire, April 2026 Ghabou

Out · last detection 17 Apr 2026, 02:52 UTC

The fire started on 16 April 2026 in Ghabou, Mauritania, and satellites saw it burning for 2 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,645 hectares from heat detections, spread across a single municipality.

It is the 14th largest in Guidimaka since 2016 (of 56 with a page). Number 8 in Mauritania in 2026, of 31.

This area had burned before

85% of the perimeter overlaps earlier fires recorded since 2016: 1,137 ha in 2024, 2,035 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 2,256 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.

CAMS · Copernicus

On 16 April 2026 the air beside the fire reached 52 µg/m³ of PM2.5. That day averaged 38: 2.5 times the WHO daily guideline (15).

Frequently asked questions

How long did the Ghabou fire last?
GWIS (Copernicus) dates it between 16 April 2026 and 17 April 2026: 2 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 2,645 hectares (26.4 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Ghabou (2,661 ha, 0.8 %).
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.
