The fire started on 6 August 2022 in Andulo, Angola, and satellites saw it burning for 20 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 7,133 hectares from heat detections, spread across a single municipality.

It is the 39th largest in Bié since 2016 (of 64 with a page). Number 56 in Angola in 2022, of 143.

This area had burned before

55% of the perimeter overlaps earlier fires recorded since 2016: 114 ha in 2016, 38 ha in 2017, 1 ha in 2018, 1,213 ha in 2019, 3,346 ha in 2021. Part of it burned more than once, so the yearly figures add up to more than the 3,906 ha that had burned before.

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.
