Lubao fire, 28 July 2025 Lubao

Out · last detection 5 Aug 2025, 11:48 UTC

The fire started on 28 July 2025 in Lubao, Democratic Republic of the Congo, and satellites saw it burning for 9 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 7,869 hectares from heat detections, spread across a single municipality.

It is the 19th largest in Lomami since 2016 (of 66 with a page). Number 46 in Democratic Republic of the Congo in 2025, of 118.

This area had burned before

96% of the perimeter overlaps earlier fires recorded since 2016: 3,299 ha in 2016, 2,582 ha in 2017, 2,628 ha in 2018, 2,564 ha in 2019, 3,152 ha in 2020, 3,775 ha in 2021, 2,063 ha in 2022, 3,772 ha in 2023, 3,370 ha in 2024. Part of it burned more than once, so the yearly figures add up to more than the 7,544 ha that had burned before.

How big is it?

It burned the equivalent of 5% of the area of London (79 km² against 1,583 km²).

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 2025
Built-up area0.98 ha
Residents≈ 250

Inside the perimeter there were about 0.98 hectares of built-up land and about 250 residents (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 Lubao fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 28 July 2025 to 5 August 2025 (9 days). The perimeter dates it from 29 July 2025 to 2 August 2025.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 7,869 hectares (78.7 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Lubao (7,916 ha, 0.4 %).
What was the weather like?
During the fire the temperature reached 36.5 °C, humidity dropped to 14 % and gusts hit 48 km/h. The fire danger index (FWI) reached 51, class Extreme.
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.
  • Dates adjusted with the VIIRS detections inside the perimeter, which said 29 July 2025 to 2 August 2025. 273 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.
