Neya fire, February 2025 Neya, Sandor
The fire started on 25 February 2025 in Neya, Sierra Leone, and satellites saw it burning for 8 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 1,337 hectares from heat detections, spread across 2 municipalities.
It is the 558th largest in Northern since 2016 (of 1112 with a page). Number 42 in Sierra Leone in 2025, of 103.

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
66% of the perimeter overlaps earlier fires recorded since 2016: 887 ha in 2016, 293 ha in 2019, 418 ha in 2022, 148 ha in 2024. Part of it burned more than once, so the yearly figures add up to more than the 889 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 27 February 2025 the air beside the fire reached 110 µg/m³ of PM2.5. That day averaged 82: 5.4 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Neya fire last?
- GWIS (Copernicus) dates it between 25 February 2025 and 4 March 2025: 8 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 1,337 hectares (13.4 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Neya (1,248 ha, 0.9 %); Sandor (91 ha, 0.1 %).
- 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.
