Tesker fire, 24 October 2024 Tesker, Kellé, Goudoumaria

Out · last detection 25 Oct 2024, 01:09 UTC

The fire started on 24 October 2024 in Tesker, Niger, and satellites saw it burning for 1 day. Copernicus’s global GWIS system rebuilt a burnt perimeter of 3,545 hectares from heat detections, spread across 3 municipalities.

It is the 12th largest in Zinder since 2016 (of 103 with a page). Number 12 in Niger in 2024, of 76.

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 weather day by day

ECMWF ERA5 reanalysis at the fire location, the standard reference for past weather, and the Canadian Fire Weather Index (the same system Copernicus uses), computed by WorldFires from that data. Days after the fire run until the first rain.

Frequently asked questions

How long did the Tesker fire last?
GWIS (Copernicus) dates it between 24 October 2024 and 24 October 2024: 1 day 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 3,545 hectares (35.4 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire entered 3 municipalities: Tesker (2,881 ha, 0.0 %); Kellé (463 ha, 0.1 %); Goudoumaria (199 ha, 0.0 %).
What was the weather like?
During the fire the temperature reached 36.7 °C, humidity dropped to 11 % and gusts hit 41 km/h. The fire danger index (FWI) reached 65, class Extreme.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Niger (OCHA COD-AB). 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 OCHA COD-AB (IGNN) (Creative Commons Attribution for Intergovernmental Organisations (CC BY-IGO)). 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.
