Katingan fire, 17 October 2026 Katingan

Dying down · last detection 23 Oct 2026, 17:52 UTC

The fire started on 17 October 2026 in Katingan, Indonesia, and satellites saw it burning for 7 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 1,813 hectares from heat detections, spread across a single municipality.

It is the 254th largest in Central Kalimantan since 2016 (of 315 with a page). Number 746 in Indonesia in 2026, of 1005.

Is it still active?

No detections since 23 Oct 2026, 17:52 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.

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 smoke

CAMS · Copernicus

On 15 October 2026 the air beside the fire reached 382 µg/m³ of PM2.5. That day averaged 206: 14 times the WHO daily guideline (15).

Frequently asked questions

How long did the Katingan fire last?
GWIS (Copernicus) dates it between 17 October 2026 and 23 October 2026: 7 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 1,813 hectares (18.1 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Katingan (1,825 ha, 0.1 %).
Is the Katingan fire still active?
No fire detections since 23 Oct 2026, 17:52 UTC. A lack of detections is not an official extinction.
What was the weather like?
During the fire the temperature reached 33.9 °C, humidity dropped to 45 % and gusts hit 25 km/h. The fire danger index (FWI) reached 5, class Very 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

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.
