Buru fire, 8 August 2026 Buru

Out · last detection 19 Oct 2026, 17:26 UTC

The fire started on 8 August 2026 in Buru, Indonesia, and satellites saw it burning for 72 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 67,318 hectares from heat detections, spread across a single municipality.

This page is probably a fire complex, not a single fire. GWIS merges into one perimeter the fires that touch over weeks, which in large burning seasons can join dozens of separate fires. The total area is reliable; the origin and dates refer to the whole complex.

Other fire pages in the same area and on the same dates:

It is the 2th largest in Maluku since 2016 (of 44 with a page). Number 15 in Indonesia in 2026, of 1007.

17% of the perimeter overlaps earlier fires recorded since 2016: 6,008 ha in 2019, 5,955 ha in 2023, 223 ha in 2024. Part of it burned more than once, so the yearly figures add up to more than the 11,272 ha that had burned before.

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 area11 ha
Residents≈ 1,600

Inside the perimeter there were about 11 hectares of built-up land and about 1,600 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 Buru fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 8 August 2026 to 18 October 2026 (72 days). The perimeter dates it from 14 August 2026 to 11 October 2026.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 67,318 hectares (673.2 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Buru (67,764 ha, 15 %).
Is the Buru fire still active?
No fire detections since 19 Oct 2026, 17:26 UTC. A lack of detections is not an official extinction.
What was the weather like?
During the fire the temperature reached 33.8 °C, humidity dropped to 36 % and gusts hit 44 km/h. The fire danger index (FWI) reached 35, 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.

What do you think is wrong?

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; 14 polygons grouped in this page.
  • Dates adjusted with the VIIRS detections inside the perimeter, which said 14 August 2026 to 11 October 2026. 2,292 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.

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.
