Andilamena fire, October 2024 Andilamena
Out · last detection 21 Nov 2024, 10:20 UTC
The fire started on 31 October 2024 in Andilamena, Madagascar, and satellites saw it burning for 22 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,811 hectares from heat detections, spread across a single municipality.
It is the 22th largest in Alaotra-Mangoro since 2016 (of 45 with a page). Number 21 in Madagascar in 2024, of 54.

It had gone 5 days without rain (1 mm or more) when it started. Rain came after the fire: 1.3 mm on 27 Nov.
This area had burned before
48% of the perimeter overlaps earlier fires recorded since 2016: 760 ha in 2016, 721 ha in 2017. Part of it burned more than once, so the yearly figures add up to more than the 1,363 ha that had burned before.

Frequently asked questions
- How long did the Andilamena fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 31 October 2024 to 21 November 2024 (22 days). The perimeter dates it from 7 November 2024 to 15 November 2024.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 2,811 hectares (28.1 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Andilamena (2,827 ha, 0.4 %).
- What was the weather like?
- During the fire the temperature reached 30.0 °C, humidity dropped to 26 % and gusts hit 45 km/h. The fire danger index (FWI) reached 31, class High.
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Madagascar (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.
Report an error
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 7 November 2024 to 15 November 2024. 178 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.
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.
