Komodou fire, 13 February 2023 Komodou
The fire started on 13 February 2023 in Komodou, Guinea, and satellites saw it burning for 17 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 6,002 hectares from heat detections, spread across a single municipality.
It is the 33th largest in Kankan since 2016 (of 388 with a page). Number 2 in Guinea in 2023, of 78.

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 more than two months without rain (1 mm or more) when it started. Rain came after the fire: 3.8 mm on 5 Mar.
This area had burned before
92% of the perimeter overlaps earlier fires recorded since 2016: 221 ha in 2016, 1,386 ha in 2017, 2,430 ha in 2019, 2,424 ha in 2020, 1,921 ha in 2021, 2,652 ha in 2022. Part of it burned more than once, so the yearly figures add up to more than the 5,504 ha that had burned before.

What happened to each town

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 1.4 hectares of built-up land and about 400 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 23 February 2023 the air beside the fire reached 246 µg/m³ of PM2.5. That day averaged 137: 9.1 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Komodou fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 13 February 2023 to 1 March 2023 (17 days). The perimeter dates it from 20 February 2023 to 24 February 2023.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 6,002 hectares (60.0 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Komodou (6,043 ha, 4.1 %).
- What was the weather like?
- During the fire the temperature reached 38.1 °C, humidity dropped to 13 % and gusts hit 36 km/h. The fire danger index (FWI) reached 49, class Very high.
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Guinea (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 20 February 2023 to 24 February 2023. 250 Suomi-NPP VIIRS detections on those dates.
- We have not matched this page with any official record.
- Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.
- 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 geoBoundaries ADM3 (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.
