Mlele fire, May 2024 Mlele

Out · last detection 11 Jun 2024, 11:20 UTC

The fire started on 31 May 2024 in Mlele, Tanzania, and satellites saw it burning for 12 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 4,250 hectares from heat detections, spread across a single municipality.

It is the 111th largest in Katavi since 2016 (of 213 with a page). Number 30 in Tanzania in 2024, of 70.

It had gone 33 days without rain (1 mm or more) when it started.

This area had burned before

100% of the perimeter overlaps earlier fires recorded since 2016: 1,920 ha in 2016, 2,878 ha in 2017, 2,828 ha in 2018, 2,607 ha in 2019, 2,616 ha in 2020, 1,931 ha in 2021, 3,064 ha in 2022, 2,461 ha in 2023. Part of it burned more than once, so the yearly figures add up to more than the 4,277 ha that had burned before.

How big is it?

Its twins: fires that started in the same weather

It started with an FWI of 25.4, a minimum humidity of 36% and 33 days without rain. Fires in the area that started in weather like this since 2016: 43.

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 Mlele fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 31 May 2024 to 11 June 2024 (12 days). The perimeter dates it from 6 June 2024 to 9 June 2024.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 4,250 hectares (42.5 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Mlele (4,279 ha, 0.1 %).
What was the weather like?
During the fire the temperature reached 33.4 °C, humidity dropped to 26 % and gusts hit 41 km/h. The fire danger index (FWI) reached 42, class Very 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: 43. Their median duration was 11 days and their median area 4,843 ha; 7 % went past 10,000 ha. In 39 of 43, 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 2.0 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.

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 6 June 2024 to 9 June 2024. 182 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.
