Luwu Timur fire, 23 September 2026 Luwu Timur, Konawe

Burning · last detection 2 Nov 2026, 17:09 UTC

The fire started on 23 September 2026 in Luwu Timur, Indonesia, and satellites saw it burning for 41 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 14,993 hectares from heat detections, spread across 2 municipalities.

It is the largest fire in South Sulawesi since 2016 (of 20 with a page). Number 77 in Indonesia in 2026, of 1025.

Is it still active?

Satellites detected fire on 2 Nov 2026, 17:09 UTC. Everything suggests it is still burning. 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.

It had gone 0 days without rain (1 mm or more) when it started. Rain came after the fire: 3.9 mm on 2 Nov.

This area had burned before

0% of the perimeter overlaps earlier fires recorded since 2016: 54 ha in 2019. Part of it burned more than once, so the yearly figures add up to more than the 42 ha that had burned before.

How big is it?

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 2025
Built-up area2.3 ha
Residents≈ 200

Inside the perimeter there were about 2.3 hectares of built-up land and about 200 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.

Frequently asked questions

How long did the Luwu Timur fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 23 September 2026 to 2 November 2026 (41 days). The perimeter dates it from 23 September 2026 to 30 October 2026.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 14,993 hectares (149.9 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire entered 2 municipalities: Luwu Timur (10,911 ha, 1.6 %); Konawe (4,185 ha, 0.8 %).
Is the Luwu Timur fire still active?
Yes: satellites detected fire on 2 Nov 2026, 17:09 UTC. Check the emergency service for the official status.
What was the weather like?
During the fire the temperature reached 33.3 °C, humidity dropped to 23 % and gusts hit 35 km/h. The fire danger index (FWI) reached 24, class High.
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.

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.

We will only use your email to reply about this report. Privacy. This is not an emergency service: if there is a fire now, call 112.

How we know this
  • Perimeter: GWIS (Copernicus), rebuilt from heat detections rather than mapped on imagery; 4 polygons grouped in this page.
  • Dates adjusted with the VIIRS detections inside the perimeter, which said 23 September 2026 to 30 October 2026. 424 Suomi-NPP VIIRS detections on those dates.
  • We have not matched this page with any official record.
  • Weather: ECMWF IFS model, provisional until the ERA5 reanalysis arrives.
  • 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.

How we build fire pages: methodology ›

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.
