Poso fire, 7 October 2026 Poso
The fire started on 7 October 2026 in Poso, Indonesia, and satellites saw it burning for 17 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 4,282 hectares from heat detections, spread across a single municipality.
It is the 5th largest in Central Sulawesi since 2016 (of 27 with a page). Number 265 in Indonesia in 2026, of 988.
Is it still active?
No detections since 23 Oct 2026, 05:53 UTC. That usually means no flame is visible from space any more, although hotspots may remain. Satellites pass a few times a day and cloud or smoke can hide the fire: a lack of detections is not an official extinction. Each country’s emergency service declares a fire contained or out.

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.
The weather it burned in
It had gone one day without rain (1 mm or more) when it started.
This area had burned before
16% of the perimeter overlaps earlier fires recorded since 2016: 319 ha in 2018, 145 ha in 2019, 118 ha in 2021, 233 ha in 2023. Part of it burned more than once, so the yearly figures add up to more than the 694 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.
The weather day by day
ECMWF ERA5 reanalysis at the fire location, the standard reference for past weather, and the Canadian Fire Weather Index (the same system Copernicus uses), computed by WorldFires from that data. Days after the fire run until the first rain.

The smoke
CAMS · CopernicusOn 15 October 2026 the air beside the fire reached 106 µg/m³ of PM2.5. That day averaged 84: 5.6 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Poso fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 7 October 2026 to 23 October 2026 (17 days). The perimeter dates it from 13 October 2026 to 22 October 2026.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 4,282 hectares (42.8 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Poso (4,311 ha, 0.6 %).
- Is the Poso fire still active?
- No fire detections since 23 Oct 2026, 05:53 UTC. A lack of detections is not an official extinction.
- What was the weather like?
- During the fire the temperature reached 25.2 °C, humidity dropped to 35 % and gusts hit 42 km/h. The fire danger index (FWI) reached 7, class Low.
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Indonesia (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.
Emergency number: 112

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.
