Kilombero fire, November 2024 Kilombero

Out · last detection 27 Nov 2024, 22:56 UTC

The fire started on 23 November 2024 in Kilombero, Tanzania, and satellites saw it burning for 4 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 3,564 hectares from heat detections, spread across a single municipality.

It is the 74th largest in Morogoro since 2016 (of 102 with a page). Number 50 in Tanzania in 2024, of 70.

It had gone 14 days without rain (1 mm or more) when it started. Rain came after the fire: 21.9 mm on 30 Nov.

This area had burned before

43% of the perimeter overlaps earlier fires recorded since 2016: 1,523 ha in 2016, 14 ha in 2018, 13 ha in 2019, 62 ha in 2020.

How big is it?

It burned the equivalent of 2.3% of the area of London (36 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.

Built-up area< 0.1 ha
Residents< 20

Inside the perimeter there was no noticeable built-up land and almost nobody lived there (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.

Its twins: fires that started in the same weather

It started with an FWI of 29.0, a minimum humidity of 28% and 14 days without rain. Fires in the area that started in weather like this since 2016: 24.

It was considered over on 26 Nov, and on 30 Nov 21.9 mm fell. We do not know whether the rain or the firefighters put it out. Twins with rain when they ended: 12 of 24, with a median of 2.4 mm.

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 Kilombero fire last?
GWIS (Copernicus) dates it between 23 November 2024 and 26 November 2024: 4 days between the first and last heat detection of the perimeter.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 3,564 hectares (35.6 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Kilombero (3,586 ha, 0.3 %).
What was the weather like?
During the fire the temperature reached 38.1 °C, humidity dropped to 28 % 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 Tanzania (geoBoundaries). 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: 24. Their median duration was 9 days and their median area 5,060 ha; 17 % went past 10,000 ha. In 12 of 24, 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 2.4 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.

We will only use your email to reply about this report. Privacy. This is not an emergency service: if there is a fire now, call 112.

How we know this
  • Perimeter: GWIS (Copernicus), rebuilt from heat detections rather than mapped on imagery.
  • Dates from the perimeter: the VIIRS detections inside it did not change them. 139 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.
