Kasongo-Lunda fire, 30 May 2026 Kasongo-Lunda
Out · last detection 25 Jun 2026, 12:22 UTC
The fire started on 30 May 2026 in Kasongo-Lunda, Democratic Republic of the Congo, and satellites saw it burning for 27 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 7,045 hectares from heat detections, spread across a single municipality.
Number 290 in Democratic Republic of the Congo in 2026, of 515.
GWIS near-real-time perimeter, from the layer that changed in August 2025: this fire is not compared with fires from earlier years, because since then the GWIS layer gives more and larger perimeters.

Satellites pass a few times a day and cloud or smoke can hide the fire: a lack of detections is not an official extinction. Each country’s emergency service declares a fire contained or out.

85% of the perimeter overlaps earlier fires recorded since 2016: 1,168 ha in 2016, 2,688 ha in 2017, 674 ha in 2018, 1,782 ha in 2019, 2,397 ha in 2020, 1,891 ha in 2021, 2,951 ha in 2022, 1,802 ha in 2023. Part of it burned more than once, so the yearly figures add up to more than the 5,959 ha that had burned before.

Frequently asked questions
- How long did the Kasongo-Lunda fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 30 May 2026 to 25 June 2026 (27 days). The perimeter dates it from 4 June 2026 to 20 June 2026.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 7,045 hectares (70.4 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Kasongo-Lunda (7,089 ha, 0.3 %).
- What was the weather like?
- During the fire the temperature reached 32.2 °C, humidity dropped to 26 % and gusts hit 34 km/h. The fire danger index (FWI) reached 31, class High.
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Democratic Republic of the Congo (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.
Report an error
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 4 June 2026 to 20 June 2026. 217 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 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.
