Guiaro fire, 18 November 2023 Guiaro
The fire started on 18 November 2023 in Guiaro, Burkina Faso, and satellites saw it burning for 1 day. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,245 hectares from heat detections, spread across a single municipality.
It is the 6th largest in Nazinon since 2016 (of 60 with a page). Number 60 in Burkina Faso in 2023, of 261.

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.
This area had burned before
79% of the perimeter overlaps earlier fires recorded since 2016: 1,014 ha in 2016, 708 ha in 2017, 582 ha in 2020, 13 ha in 2021. Part of it burned more than once, so the yearly figures add up to more than the 1,775 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.

Frequently asked questions
- How long did the Guiaro fire last?
- GWIS (Copernicus) dates it between 18 November 2023 and 18 November 2023: 1 day 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 2,245 hectares (22.4 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Guiaro (2,258 ha, 1.4 %).
- 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.
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 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.
