Donga fire, December 2022 Donga

Out · last detection 12 Jan 2023, 12:42 UTC

The fire started on 30 December 2022 in Donga, Nigeria, and satellites saw it burning for 14 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,534 hectares from heat detections, spread across a single municipality.

It is the 92th largest in Taraba since 2016 (of 160 with a page). Number 74 in Nigeria in 2022, of 125.

The power measured by the satellite is low (13.7 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

It had gone more than two months without rain (1 mm or more) when it started.

This area had burned before

23% of the perimeter overlaps earlier fires recorded since 2016: 281 ha in 2019, 154 ha in 2020, 298 ha in 2021, 17 ha in 2022. Part of it burned more than once, so the yearly figures add up to more than the 591 ha that had burned before.

How big is it?

10 km
It burned the equivalent of 1.6% of the area of London (25 km² against 1,583 km²).

Frequently asked questions

How long did the Donga fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 30 December 2022 to 12 January 2023 (14 days). The perimeter dates it from 2 January 2023 to 5 January 2023.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 2,534 hectares (25.3 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Donga (2,549 ha, 0.8 %).
What was the weather like?
During the fire the temperature reached 35.8 °C, humidity dropped to 22 % and gusts hit 34 km/h. The fire danger index (FWI) reached 44, 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.

How we know this
  • Perimeter: GWIS (Copernicus), rebuilt from heat detections rather than mapped on imagery.
  • Dates adjusted with the VIIRS detections inside the perimeter, which said 2 January 2023 to 5 January 2023. 75 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.

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.
