This area had burned before

89% of the perimeter overlaps earlier fires recorded since 2016: 1,564 ha in 2017, 1,817 ha in 2018, 144 ha in 2019, 233 ha in 2020, 664 ha in 2021, 3,524 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 3,685 ha that had burned before.

How big is it?

It burned the equivalent of 2.6% of the area of London (42 km² against 1,583 km²).

Residents≈ 400

Inside the perimeter there were about 4.0 hectares of built-up land and about 400 residents (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.

Frequently asked questions

How long did the Vanduzi fire last?: According to the heat detections seen by satellite inside the perimeter, it burned from 12 September 2026 to 28 September 2026 (17 days). The perimeter dates it from 13 September 2026 to 21 September 2026.
How much area did it burn?: The perimeter GWIS (Copernicus) rebuilt from heat detections is 4,152 hectares (41.5 km²). It is an estimate: official national figures may differ.
Which municipalities burned?: The fire only entered Vanduzi (4,171 ha, 1.3 %).
What was the weather like?: During the fire the temperature reached 33.6 °C, humidity dropped to 27 % and gusts hit 36 km/h. The fire danger index (FWI) reached 32, class High.
Where does this data come from?: From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Mozambique (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 13 September 2026 to 21 September 2026. 99 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.

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.
