Toliary-II fire, September 2026 Toliary-II
The fire started on 12 September 2026 in Toliary-II, Madagascar, and satellites saw it burning for 9 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,272 hectares from heat detections, spread across a single municipality.
It is the 42th largest in Atsimo-Andrefana since 2016 (of 45 with a page). Number 71 in Madagascar in 2026, of 94.

Fire radiative power detected each day, in megawatts, and number of hotspots. The magenta bar marks the peak day.
The weather it burned in
It had gone 24 days without rain (1 mm or more) when it started. Rain came after the fire: 4.0 mm on 26 Sept.
This area had burned before
98% of the perimeter overlaps earlier fires recorded since 2016: 462 ha in 2016, 3,245 ha in 2017, 1,067 ha in 2018, 2,803 ha in 2019, 1,811 ha in 2020, 685 ha in 2021, 426 ha in 2022, 1,778 ha in 2023, 1,234 ha in 2024, 1,461 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 2,218 ha that had burned before.

What happened to each town

Toliary-II where it started2,280 ha reached on 12 Sept0.2 %
Burnt area inside each municipality, from crossing the GWIS perimeter with administrative boundaries. The distance runs from the point marking the centre of each area to the nearest fire: staying a kilometre away does not mean it reached the houses.
People and buildings inside the perimeter
GHSL 2025Inside the perimeter there were about 0.05 hectares of built-up land and about 50 residents (GHSL 2025, satellite-based estimate).
This is an estimate on 100 m cells, made from satellite imagery and census data: it does not mean that homes burned or that anyone was harmed. The perimeter also contains land that never burned. The GHSL 2025 epoch is a projection made from 2020 and earlier data.

The smoke
CAMS · CopernicusOn 20 September 2026 the air beside the fire reached 20 µg/m³ of PM2.5, but no daily average passed the WHO guideline (15).

Frequently asked questions
- How long did the Toliary-II fire last?
- GWIS (Copernicus) dates it between 12 September 2026 and 20 September 2026: 9 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 2,272 hectares (22.7 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Toliary-II (2,280 ha, 0.2 %).
- What was the weather like?
- During the fire the temperature reached 32.8 °C, humidity dropped to 18 % and gusts hit 47 km/h. The fire danger index (FWI) reached 48, class Very 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 from the perimeter: the VIIRS detections inside it did not change them. 43 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.
- Built-up area and population come from the JRC Global Human Settlement Layer (epoch 2025, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.
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.
