Mampikony fire, September 2024 Mampikony
Out · last detection 15 Oct 2024, 21:23 UTC
The fire started on 29 September 2024 in Mampikony, Madagascar, and satellites saw it burning for 17 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 3,310 hectares from heat detections, spread across a single municipality.
It is the 29th largest in Sofia since 2016 (of 116 with a page). Number 14 in Madagascar in 2024, of 54.

How a twin is chosen
- Same area: fires that have already ended, less than 250 km from this one, since 2024.
- Same start: we compare the FWI on the first day, the minimum humidity that day and the run of days without rain before it. The slider sets how much they may differ.
- Only pages with final weather data (ERA5 reanalysis) calculated in the same way as this fire’s; agricultural and grass burns and pages with data under review are left out.
- Fires burning at the same time as this one (a week before or after) are left out: they share the same spell of weather and do not count as a precedent.
- They are sorted by similarity, and the outlines of the first five are drawn.

Frequently asked questions
- How long did the Mampikony fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 29 September 2024 to 15 October 2024 (17 days). The perimeter dates it from 2 October 2024 to 12 October 2024.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 3,310 hectares (33.1 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Mampikony (3,326 ha, 0.7 %).
- What was the weather like?
- During the fire the temperature reached 35.3 °C, humidity dropped to 21 % and gusts hit 55 km/h. The fire danger index (FWI) reached 67, class Extreme.
- 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 2 October 2024 to 12 October 2024. 187 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.
