Anka fire, 8 December 2020 Anka
The fire started on 8 December 2020 in Anka, Nigeria, and satellites saw it burning for 5 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,429 hectares from heat detections, spread across a single municipality.
It is the 145th largest in Zamfara since 2016 (of 208 with a page). Number 96 in Nigeria in 2020, of 150.
The power measured by the satellite is low (12.6 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

How it evolved, day by day
Fire radiative power detected each day, in megawatts, and number of hotspots. The magenta bar marks the peak day.
This area had burned before
57% of the perimeter overlaps earlier fires recorded since 2016: 917 ha in 2016, 291 ha in 2017, 140 ha in 2018, 119 ha in 2019. Part of it burned more than once, so the yearly figures add up to more than the 1,378 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 Anka fire last?
- GWIS (Copernicus) dates it between 8 December 2020 and 12 December 2020: 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 2,429 hectares (24.3 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Anka (2,444 ha, 0.9 %).
- 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.

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.
