Kasongo-Lunda fire, 30 July 2026 Kasongo-Lunda

Out · last detection 28 Aug 2026, 12:23 UTC

The fire started on 30 July 2026 in Kasongo-Lunda, Democratic Republic of the Congo, and satellites saw it burning for 30 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 34,684 hectares from heat detections, spread across a single municipality.

Number 29 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.

It had gone more than two months without rain (1 mm or more) when it started. Rain came after the fire: 6.0 mm on 29 Aug.

This area had burned before

79% of the perimeter overlaps earlier fires recorded since 2016: 16,311 ha in 2016, 5,856 ha in 2017, 3,374 ha in 2018, 1 ha in 2019, 16,313 ha in 2020, 9,253 ha in 2021, 4,556 ha in 2022, 6,887 ha in 2023, 6,479 ha in 2024, 8,812 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 27,391 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 July 2026 to 28 August 2026 (30 days). The perimeter dates it from 5 August 2026 to 27 August 2026.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 34,684 hectares (346.8 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Kasongo-Lunda (35,239 ha, 1.3 %).
What was the weather like?
During the fire the temperature reached 33.6 °C, humidity dropped to 18 % and gusts hit 32 km/h. The fire danger index (FWI) reached 49, class Very 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.

How we know this
  • Perimeter: GWIS (Copernicus), rebuilt from heat detections rather than mapped on imagery; 3 polygons grouped in this page.
  • Dates adjusted with the VIIRS detections inside the perimeter, which said 5 August 2026 to 27 August 2026. 866 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.

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.
