Tomora fire, 14 November 2025 Tomora, Ségala, Diakon

Out · last detection 16 Nov 2025, 14:47 UTC

The fire started on 14 November 2025 in Tomora, Mali, and satellites saw it burning for 4 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,378 hectares from heat detections, spread across 3 municipalities.

It is the 230th largest in Kayes since 2016 (of 337 with a page). Number 207 in Mali in 2025, of 282.

This area had burned before

83% of the perimeter overlaps earlier fires recorded since 2016: 1,013 ha in 2016, 7 ha in 2019, 391 ha in 2020, 1,344 ha in 2021. Part of it burned more than once, so the yearly figures add up to more than the 1,965 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.

Frequently asked questions

How long did the Tomora fire last?
GWIS (Copernicus) dates it between 14 November 2025 and 17 November 2025: 4 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 2,378 hectares (23.8 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire entered 3 municipalities: Tomora (1,886 ha, 1.0 %); Ségala (451 ha, 0.4 %); Diakon (57 ha, 0.0 %).
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Mali (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 International (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.
