Anka fire, 28 November 2025 Anka

Out · last detection 9 Dec 2025, 01:27 UTC

The fire started on 28 November 2025 in Anka, Nigeria, and satellites saw it burning for 12 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 8,176 hectares from heat detections, spread across a single municipality.

It is the 12th largest in Zamfara since 2016 (of 209 with a page). Number 27 in Nigeria in 2025, of 294.

The power measured by the satellite is low (27.0 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

This area had burned before

94% of the perimeter overlaps earlier fires recorded since 2016: 3,560 ha in 2016, 5,164 ha in 2017, 640 ha in 2018, 2,960 ha in 2019, 770 ha in 2020, 6,271 ha in 2021, 1,635 ha in 2022, 1,254 ha in 2023, 2,864 ha in 2024. Part of it burned more than once, so the yearly figures add up to more than the 7,697 ha that had burned before.

How big is it?

10 km
It burned the equivalent of 5.2% of the area of London (82 km² against 1,583 km²).

Burnt area inside each municipality, from crossing the GWIS perimeter with administrative boundaries. The distance runs from the point marking the centre of each area to the nearest fire: staying a kilometre away does not mean it reached the houses.

People and buildings inside the perimeter

GHSL 2025
Built-up area0.63 ha
Residents≈ 200

Inside the perimeter there were about 0.63 hectares of built-up land and about 200 residents (GHSL 2025, satellite-based estimate).

This is an estimate on 100 m cells, made from satellite imagery and census data: it does not mean that homes burned or that anyone was harmed. The perimeter also contains land that never burned. The GHSL 2025 epoch is a projection made from 2020 and earlier data.

Frequently asked questions

How long did the Anka fire last?
GWIS (Copernicus) dates it between 28 November 2025 and 9 December 2025: 12 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 8,176 hectares (81.8 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Anka (8,222 ha, 3.2 %).
What was the weather like?
During the fire the temperature reached 36.8 °C, humidity dropped to 21 % and gusts hit 41 km/h. The fire danger index (FWI) reached 48, class Very high.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Nigeria (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.

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.

We will only use your email to reply about this report. Privacy. This is not an emergency service: if there is a fire now, call 112.

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. 191 Suomi-NPP VIIRS detections on those dates.
  • We have not matched this page with any official record.
  • Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.
  • Built-up area and population come from the JRC Global Human Settlement Layer (epoch 2025, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.

How we build fire pages: methodology ›

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 ADM2 (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.
