Tane fire, 30 March 2023 Tane, Kafe Simiria
The fire started on 30 March 2023 in Tane, Sierra Leone, and satellites saw it burning for 12 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 1,427 hectares from heat detections, spread across 2 municipalities.
It is the 476th largest in Northern since 2016 (of 1112 with a page). Number 62 in Sierra Leone in 2023, of 158.

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
12% of the perimeter overlaps earlier fires recorded since 2016: 155 ha in 2017, 24 ha in 2018, 5 ha in 2022. Part of it burned more than once, so the yearly figures add up to more than the 166 ha that had burned before.

The smoke
CAMS · CopernicusOn 12 April 2023 the air beside the fire reached 349 µg/m³ of PM2.5. That day averaged 208: 14 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Tane fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 30 March 2023 to 10 April 2023 (12 days). The perimeter dates it from 5 April 2023 to 10 April 2023.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 1,427 hectares (14.3 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Tane (1,425 ha, 3.2 %); Kafe Simiria (12 ha, 0.0 %).
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Sierra Leone (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 5 April 2023 to 10 April 2023. 40 Suomi-NPP VIIRS detections on those dates.
- We have not matched this page with any official record.
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 4.0 (CC BY 4.0)). 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.
