Kunike fire, April 2026 Kunike

Out · last detection 23 Apr 2026, 13:47 UTC

The fire started on 18 April 2026 in Kunike, Sierra Leone, and satellites saw it burning for 6 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 1,394 hectares from heat detections, spread across a single municipality.

It is the 506th largest in Northern since 2016 (of 1112 with a page). Number 166 in Sierra Leone in 2026, of 305.

Frequently asked questions

How long did the Kunike fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 18 April 2026 to 23 April 2026 (6 days). The perimeter dates it from 18 April 2026 to 21 April 2026.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 1,394 hectares (13.9 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Kunike (1,404 ha, 1.8 %).
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.
