Raga fire, 24 December 2024 Raga

Out · last detection 23 Jan 2025, 10:48 UTC

The fire started on 24 December 2024 in Raga, South Sudan, and satellites saw it burning for 31 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 18,354 hectares from heat detections, spread across a single municipality.

It is the 50th largest in Western Bahr el Ghazal since 2016 (of 338 with a page). Number 22 in South Sudan in 2024, of 180.

This area had burned before

92% of the perimeter overlaps earlier fires recorded since 2016: 8,113 ha in 2016, 3,396 ha in 2017, 1,905 ha in 2018, 7,024 ha in 2019, 7,217 ha in 2020, 7,817 ha in 2021, 2,644 ha in 2022, 616 ha in 2023. Part of it burned more than once, so the yearly figures add up to more than the 16,881 ha that had burned before.

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.

It was 2.0 times larger than the median of its twins and lasted 31 days, against 15 days.

Only 3 of its 22 twins burned more. The weather on the first day does not explain everything: the wind in the following days, the fuel and the firefighting also count. In none of them did 1 mm fall in the ten days after the end: they all went out without rain.

This is a bank of analogues: it shows what usually happens, not what will happen. With fewer than 15 twins we give no figures. How we calculate it

It was considered over on 23 Jan, and not even 1 mm fell in the following ten days: it went out without rain. None of its 22 twins had rain when they ended.

How a twin is chosen

  • Same area: fires that have already ended, less than 250 km from this one, since 2016.
  • Same start: we compare the FWI on the first day, the minimum humidity that day and the run of days without rain before it. The slider sets how much they may differ.
  • Only pages with final weather data (ERA5 reanalysis) calculated in the same way as this fire’s; agricultural and grass burns and pages with data under review are left out.
  • Fires burning at the same time as this one (a week before or after) are left out: they share the same spell of weather and do not count as a precedent.
  • They are sorted by similarity, and the outlines of the first five are drawn.

Frequently asked questions

How long did the Raga fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 24 December 2024 to 23 January 2025 (31 days). The perimeter dates it from 31 December 2024 to 16 January 2025.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 18,354 hectares (183.5 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Raga (18,441 ha, 0.3 %).
What was the weather like?
During the fire the temperature reached 37.4 °C, humidity dropped to 9 % and gusts hit 41 km/h. The fire danger index (FWI) reached 58, 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.
How did the fires that started in similar weather in this area end?
Fires less than 250 km away that started since 2016 with a similar FWI, humidity and dry spell: 22. Their median duration was 15 days and their median area 8,994 ha; 41 % went past 10,000 ha. Only 3 of its 22 twins burned more. The weather on the first day does not explain everything: the wind in the following days, the fuel and the firefighting also count. In none of them did 1 mm fall in the ten days after the end: they all went out without rain.

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 31 December 2024 to 16 January 2025. 1,216 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 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.
