Moba fire, 17 September 2022 Moba
The fire started on 17 September 2022 in Moba, Democratic Republic of the Congo, and satellites saw it burning for 18 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 6,360 hectares from heat detections, spread across a single municipality.
It is the 126th largest in Tanganyika since 2016 (of 232 with a page). Number 55 in Democratic Republic of the Congo in 2022, of 106.

Where it burned
How it evolved, day by day
Fire radiative power detected each day, in megawatts, and number of hotspots. The magenta bar marks the peak day.
The weather it burned in
It had gone 0 days without rain (1 mm or more) when it started. Rain came after the fire: 1.5 mm on 29 Sept.
This area had burned before
92% of the perimeter overlaps earlier fires recorded since 2016: 3,483 ha in 2016, 1,681 ha in 2017, 965 ha in 2018, 1,778 ha in 2019, 4,764 ha in 2020, 1,021 ha in 2021. Part of it burned more than once, so the yearly figures add up to more than the 5,820 ha that had burned before.

What happened to each town

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 were about 4.7 hectares of built-up land and about 1,100 residents (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.

The smoke
CAMS · CopernicusOn 5 October 2022 the air beside the fire reached 136 µg/m³ of PM2.5. That day averaged 82: 5.4 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Moba fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 17 September 2022 to 4 October 2022 (18 days). The perimeter dates it from 20 September 2022 to 27 September 2022.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 6,360 hectares (63.6 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Moba (6,399 ha, 0.2 %).
- What was the weather like?
- During the fire the temperature reached 26.9 °C, humidity dropped to 30 % and gusts hit 35 km/h. The fire danger index (FWI) reached 25, 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.

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 20 September 2022 to 27 September 2022. 252 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.
