Kollet fire, April 2024 Kollet, Sogolon

Out · last detection 18 Apr 2024, 15:02 UTC

The fire started on 16 April 2024 in Kollet, Guinea, and satellites saw it burning for 3 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,561 hectares from heat detections, spread across 2 municipalities.

It is the 156th largest in Kindia since 2016 (of 242 with a page). Number 58 in Guinea in 2024, of 118.

This area had burned before

88% of the perimeter overlaps earlier fires recorded since 2016: 1,518 ha in 2016, 862 ha in 2017, 370 ha in 2019, 414 ha in 2020, 1,693 ha in 2021, 550 ha in 2023. Part of it burned more than once, so the yearly figures add up to more than the 2,245 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 19 April 2024 the air beside the fire reached 62 µg/m³ of PM2.5. That day averaged 57: 3.8 times the WHO daily guideline (15).

Frequently asked questions

How long did the Kollet fire last?
GWIS (Copernicus) dates it between 16 April 2024 and 18 April 2024: 3 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 2,561 hectares (25.6 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire entered 2 municipalities: Kollet (2,200 ha, 4.4 %); Sogolon (376 ha, 0.6 %).
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.

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 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.
