How long did the Kunike fire last?

GWIS (Copernicus) dates it between 15 April 2017 and 19 April 2017: 5 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 1,029 hectares (10.3 km²). It is an estimate: official national figures may differ.

Which municipalities burned?

The fire entered 3 municipalities: Kunike (881 ha, 1.1 %); Kunike Barina (148 ha, 0.4 %); Kafe Simiria (6 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.

Kunike fire, 15 April 2017 Kunike, Kunike Barina, Kafe Simiria

Out · last detection 19 Apr 2017, 13:44 UTC

The fire started on 15 April 2017 in Kunike, Sierra Leone, and satellites saw it burning for 5 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 1,029 hectares from heat detections, spread across 3 municipalities.

It is the 1034th largest in Northern since 2016 (of 1112 with a page). Number 194 in Sierra Leone in 2017, of 207.

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 from the perimeter: the VIIRS detections inside it did not change them. 21 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.
