Gummi fire, January 2021 Gummi
The fire started on 6 January 2021 in Gummi, Nigeria, and satellites saw it burning for 12 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 5,926 hectares from heat detections, spread across a single municipality.
It is the 22th largest in Zamfara since 2016 (of 209 with a page). Number 20 in Nigeria in 2021, of 184.

Where it burned
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.
The weather it burned in
It had gone more than two months without rain (1 mm or more) when it started.
This area had burned before
67% of the perimeter overlaps earlier fires recorded since 2016: 1,389 ha in 2016, 833 ha in 2017, 552 ha in 2019, 3,501 ha in 2020. Part of it burned more than once, so the yearly figures add up to more than the 3,974 ha that had burned before.

What happened to each town
-
Gummi where it started5,960 ha reached on 2 Jan2.0 %
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 2020Inside the perimeter there were about 0.17 hectares of built-up land and about 30 residents (GHSL 2020, 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.

Frequently asked questions
- How long did the Gummi fire last?
- GWIS (Copernicus) dates it between 6 January 2021 and 17 January 2021: 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 5,926 hectares (59.3 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Gummi (5,960 ha, 2.0 %).
- What was the weather like?
- During the fire the temperature reached 38.4 °C, humidity dropped to 9 % and gusts hit 43 km/h. The fire danger index (FWI) reached 63, class Extreme.
- 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.

How we know this
- Perimeter: GWIS (Copernicus), rebuilt from heat detections rather than mapped on imagery; 2 polygons grouped in this page.
- Dates from the perimeter: the VIIRS detections inside it did not change them. 233 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 2020, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.
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.
