Out · last detection 22 Jan 2025, 11:06 UTC

The fire started on 23 December 2024 in Nzara, South Sudan, and satellites saw it burning for 31 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 18,875 hectares from heat detections, spread across a single municipality.

It is the 60th largest in Western Equatoria since 2016 (of 361 with a page). Number 19 in South Sudan in 2024, of 185.

This area had burned before

99% of the perimeter overlaps earlier fires recorded since 2016: 7,574 ha in 2016, 7,434 ha in 2017, 1,319 ha in 2018, 7,170 ha in 2019, 13,082 ha in 2020, 1,137 ha in 2021, 13,617 ha in 2022, 826 ha in 2023, 5,766 ha in 2024. Part of it burned more than once, so the yearly figures add up to more than the 18,758 ha that had burned before.

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.

Inside the perimeter there was no noticeable built-up land and almost nobody lived there (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 Nzara fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 23 December 2024 to 22 January 2025 (31 days). The perimeter dates it from 30 December 2024 to 19 January 2025.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 18,875 hectares (188.8 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Nzara (19,015 ha, 2.9 %).
What was the weather like?
During the fire the temperature reached 37.5 °C, humidity dropped to 12 % and gusts hit 41 km/h. The fire danger index (FWI) reached 54, class Extreme.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of South Sudan (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 adjusted with the VIIRS detections inside the perimeter, which said 30 December 2024 to 19 January 2025. 688 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.

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 3.0 Intergovernmental Organisations (CC BY 3.0 IGO)). 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.
