Konsotami fire, 8 April 2021 Konsotami, Koba, Missira
The fire started on 8 April 2021 in Konsotami, Guinea, and satellites saw it burning for 16 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 5,736 hectares from heat detections, spread across 4 municipalities.
It is the 34th largest in Kindia since 2016 (of 242 with a page). Number 12 in Guinea in 2021, of 113.

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.
This area had burned before
76% of the perimeter overlaps earlier fires recorded since 2016: 1,854 ha in 2016, 2,742 ha in 2017, 2,786 ha in 2018, 674 ha in 2019, 1,070 ha in 2020. Part of it burned more than once, so the yearly figures add up to more than the 4,372 ha that had burned before.

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 2020Inside the perimeter there were about 7.2 hectares of built-up land and about 1,600 residents (GHSL 2020, 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.

Frequently asked questions
- How long did the Konsotami fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 8 April 2021 to 23 April 2021 (16 days). The perimeter dates it from 12 April 2021 to 18 April 2021.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 5,736 hectares (57.4 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 4 municipalities: Konsotami (2,180 ha, 2.5 %); Koba (1,829 ha, 2.4 %); Missira (1,176 ha, 1.0 %); Tarihoye (587 ha, 1.1 %).
- What was the weather like?
- During the fire the temperature reached 36.8 °C, humidity dropped to 29 % and gusts hit 38 km/h. The fire danger index (FWI) reached 41, 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 12 April 2021 to 18 April 2021. 229 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 2020, 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.
