Yoni fire, 14 April 2026 Yoni, Fakunya
The fire started on 14 April 2026 in Yoni, Sierra Leone, and satellites saw it burning for 13 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 1,413 hectares from heat detections, spread across 2 municipalities.
It is the 488th largest in Northern since 2016 (of 1112 with a page). Number 161 in Sierra Leone in 2026, of 305.

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
73% of the perimeter overlaps earlier fires recorded since 2016: 492 ha in 2016, 664 ha in 2020. Part of it burned more than once, so the yearly figures add up to more than the 1,031 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.

The smoke
CAMS · CopernicusOn 21 April 2026 the air beside the fire reached 69 µg/m³ of PM2.5. That day averaged 49: 3.3 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Yoni fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 14 April 2026 to 26 April 2026 (13 days). The perimeter dates it from 16 April 2026 to 21 April 2026.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 1,413 hectares (14.1 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Yoni (1,152 ha, 0.9 %); Fakunya (270 ha, 0.5 %).
- 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.
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 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.
