Mlele fire, 1 August 2024 Mlele

Out · last detection 8 Aug 2024, 11:34 UTC

The fire started on 1 August 2024 in Mlele, Tanzania, and satellites saw it burning for 7 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 5,969 hectares from heat detections, spread across a single municipality.

It is the 84th largest in Katavi since 2016 (of 271 with a page). Number 14 in Tanzania in 2024, of 70.

The power measured by the satellite is low (22.4 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

It had gone more than two months without rain (1 mm or more) when it started.

This area had burned before

99% of the perimeter overlaps earlier fires recorded since 2016: 4,467 ha in 2016, 3,586 ha in 2017, 749 ha in 2018, 3,466 ha in 2019, 2,368 ha in 2020, 1,755 ha in 2021, 1,718 ha in 2022, 2,865 ha in 2023. Part of it burned more than once, so the yearly figures add up to more than the 5,924 ha that had burned before.

Burnt area inside each municipality, from crossing the GWIS perimeter with administrative boundaries. The distance is from the town centre to the nearest fire: staying a kilometre away does not mean it reached the houses.

Frequently asked questions

How long did the Mlele fire last?
GWIS (Copernicus) dates it between 1 August 2024 and 7 August 2024: 7 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 5,969 hectares (59.7 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Mlele (6,012 ha, 0.2 %).
What was the weather like?
During the fire the temperature reached 33.8 °C, humidity dropped to 13 % and gusts hit 43 km/h. The fire danger index (FWI) reached 50, class Extreme.
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.

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.

Emergency number: 112

Satellite cross-check

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.

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.
