Manja fire, November 2023 Manja
The fire started on 11 November 2023 in Manja, Madagascar, and satellites saw it burning for 3 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,091 hectares from heat detections, spread across a single municipality.
It is the 84th largest in Menabe since 2016 (of 98 with a page). Number 31 in Madagascar in 2023, of 32.

Where it burned
How it evolved, day by day
Fire radiative power detected each day, in megawatts, and number of hotspots. The magenta bar marks the peak day.
This area had burned before
100% of the perimeter overlaps earlier fires recorded since 2016: 936 ha in 2016, 1,596 ha in 2017, 177 ha in 2019, 2,017 ha in 2020. Part of it burned more than once, so the yearly figures add up to more than the 2,101 ha that had burned before.

What happened to each town

Burnt area inside each municipality, from crossing the GWIS perimeter with administrative boundaries. The distance is from the town centre to the nearest fire: staying a kilometre away does not mean it reached the houses.

Frequently asked questions
- How long did the Manja fire last?
- GWIS (Copernicus) dates it between 11 November 2023 and 13 November 2023: 3 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 2,091 hectares (20.9 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Manja (2,098 ha, 0.2 %).
- 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.
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 (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.
