Djambala fire, 18 July 2024 Djambala
Out · last detection 20 Jul 2024, 12:32 UTC
The fire started on 18 July 2024 in Djambala, Republic of the Congo, and satellites saw it burning for 5 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 1,489 hectares from heat detections, spread across a single municipality.
It is the 59th largest in Plateaux since 2016 (of 196 with a page). Number 28 in Republic of the Congo in 2024, of 103.
The power measured by the satellite is low (22.1 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

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 Djambala fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 18 July 2024 to 22 July 2024 (5 days). The perimeter dates it from 18 July 2024 to 20 July 2024.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 1,489 hectares (14.9 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Djambala (1,498 ha, 0.1 %).
- What was the weather like?
- During the fire the temperature reached 29.3 °C, humidity dropped to 52 % and gusts hit 37 km/h. The fire danger index (FWI) reached 18, class Moderate.
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Republic of the Congo (geoBoundaries ADM2). 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: 18. Their median duration was 3 days and their median area 1,368 ha; 100 % went past 1,000 ha. In 9 of 18, not even 1 mm fell in the ten days after the end: they went out without rain. In the rest, the first rainy day brought a median of 1.3 mm.
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 18 July 2024 to 20 July 2024. 34 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 (Map Library 2007, nombres de Wikidata) (Public Domain). 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.
