Pibor fire, 27 January 2022 Pibor
The fire started on 27 January 2022 in Pibor, South Sudan, and satellites saw it burning for 6 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 7,749 hectares from heat detections, spread across a single municipality.
It is the 190th largest in Jonglei since 2016 (of 427 with a page). Number 58 in South Sudan in 2022, of 124.

We have the GWIS perimeter for this fire, but the VIIRS sensors did not capture it in enough detail: no day-by-day evolution, but the split by municipality is there.

Where it burned
The weather it burned in
It had gone 9 days without rain (1 mm or more) when it started.
This area had burned before
75% of the perimeter overlaps earlier fires recorded since 2016: 2,948 ha in 2016, 202 ha in 2017, 422 ha in 2019, 1,577 ha in 2020, 3,076 ha in 2021. Part of it burned more than once, so the yearly figures add up to more than the 5,827 ha that had burned before.

What happened to each town

Pibor where it started7,799 ha0.2 %
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 was no noticeable built-up land and almost nobody lived there (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 Pibor fire last?
- GWIS (Copernicus) dates it between 27 January 2022 and 1 February 2022: 6 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 7,749 hectares (77.5 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Pibor (7,799 ha, 0.2 %).
- What was the weather like?
- During the fire the temperature reached 37.2 °C, humidity dropped to 17 % and gusts hit 26 km/h. The fire danger index (FWI) reached 36, class High.
- 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.
- Dates from the perimeter: the VIIRS detections inside it did not change them. No 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 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.
