Caungula fire, 1 August 2023 Caungula

Out · last detection 12 Aug 2023, 11:22 UTC

The fire started on 1 August 2023 in Caungula, Angola, and satellites saw it burning for 12 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 5,145 hectares from heat detections, spread across a single municipality.

It is the 380th largest in Lunda Norte since 2016 (of 411 with a page). Number 150 in Angola in 2023, of 158.

It had gone 52 days without rain (1 mm or more) when it started. Rain came after the fire: 1.1 mm on 22 Aug.

This area had burned before

94% of the perimeter overlaps earlier fires recorded since 2016: 1,400 ha in 2016, 2,791 ha in 2017, 1,378 ha in 2018, 583 ha in 2019, 4,266 ha in 2020, 1,572 ha in 2021, 554 ha in 2022. Part of it burned more than once, so the yearly figures add up to more than the 4,848 ha that had burned before.

How big is it?

10 km
It burned the equivalent of 3.2% of the area of London (51 km² against 1,583 km²).

Frequently asked questions

How long did the Caungula fire last?
GWIS (Copernicus) dates it between 1 August 2023 and 12 August 2023: 12 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 5,145 hectares (51.4 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Caungula (5,176 ha, 0.4 %).
What was the weather like?
During the fire the temperature reached 33.1 °C, humidity dropped to 14 % and gusts hit 46 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 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.

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 from the perimeter: the VIIRS detections inside it did not change them. 214 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 (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.
