Andulo fire, August 2025 Andulo, Mussende

Out · last detection 15 Sept 2025, 12:20 UTC

The fire started on 29 August 2025 in Andulo, Angola, and satellites saw it burning for 17 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 7,677 hectares from heat detections, spread across 2 municipalities.

It is the 32th largest in Bié since 2016 (of 64 with a page). Number 83 in Angola in 2025, of 191.

It had gone 0 days without rain (1 mm or more) when it started. Rain came after the fire: 2.0 mm on 17 Sept.

This area had burned before

73% of the perimeter overlaps earlier fires recorded since 2016: 729 ha in 2016, 941 ha in 2017, 1,257 ha in 2020, 157 ha in 2021, 1,411 ha in 2022, 2,708 ha in 2023, 2,811 ha in 2024. Part of it burned more than once, so the yearly figures add up to more than the 5,580 ha that had burned before.

Frequently asked questions

How long did the Andulo fire last?
GWIS (Copernicus) dates it between 29 August 2025 and 14 September 2025: 17 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 7,677 hectares (76.8 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire entered 2 municipalities: Andulo (7,659 ha, 0.8 %); Mussende (61 ha, 0.0 %).
What was the weather like?
During the fire the temperature reached 30.5 °C, humidity dropped to 15 % and gusts hit 55 km/h. The fire danger index (FWI) reached 49, class Very high.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Angola (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.

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.

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 (Public Domain). 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.
