The fire started on 13 September 2026 in Bombana, Indonesia, and satellites saw it burning for 57 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 12,483 hectares from heat detections, spread across 2 municipalities.
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.
Number 47 in Indonesia in 2026, of 979.
GWIS near-real-time perimeter, from the layer that changed in October 2025: this fire is not compared with fires from earlier years, because since then the GWIS layer gives more and larger perimeters.

Union of 6 GWIS (Copernicus) perimeters: overlapping areas count once.
No official record is matched to this page to compare it with.
From 13 Sept 2026 to today: still being detected.
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.
First day with fire seen by the satellites or the perimeter.
No official record is matched to this page, so the alert time and the cause are not known here.
VIIRS detections at 375 m. Most intense hotspot: 249 MW.
There is no official record to compare with. Each hotspot is a pixel detected in one satellite pass, not a separate fire.
Total radiative power on 29 October 2026; hotspots that day: 54.
Fire radiative power (FRP) measures the energy the fire gives off when the satellite passes. Added up by day, it compares intensity, not area.
Fire Weather Index (Canadian system) computed by WorldFires for the day the fire started. Consecutive days without rain before: 10.
This is an index computed from weather model data, not a measurement of the fire nor an official warning. Danger warnings are issued by each country’s authority. Emergency number and official warnings
High of 37.4 °C and minimum humidity of 30% on 25 October 2026; gusts of 46 km/h on 18 September 2026.
These are model values for a cell of about 25 km, not from a weather station: they may differ from what was measured on the ground.
Estimated residents inside the perimeter and 6.2 ha of built-up area (100 m grid, epoch 2025).
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.
This page’s change log has been kept since 24 October 2026: every night what it publishes is compared and the difference is logged. Anything earlier is reconstructed from each source’s date and marked as reconstructed.
Move the slider to see which area the page published each day.
A version keeps the area, dates, name and official record; the area as it was logged (changes under 2% are not logged). The map, hotspots and weather always show today’s data.

Satellites detected fire on 9 Nov 2026, 05:33 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.
The wind is blowing from the east and pushing westwards; no sharp shifts are expected until Fri 13, 00:00.

Chance of rain up to 61 % in those hours. It can slow the fire at the surface, but that does not mean it will go out.
Checked, no warning: no wind shifts of more than 60° nights recover humidity (peaks of 94 % or more)

We compare your point with the fan for each hour. Your location never leaves your device.
or tap the mapThis is not an official warning. It is a global model forecast with cells of about 25 km, at the centre of the fire: it cannot see valley winds or the winds the fire itself creates. The fan shows where the wind blows, not where the fire will spread. If in doubt, follow what the authorities say.
Emergencies · Indonesia 112 Emergency number and official warningsForecast: ECMWF IFS 0.25° (European Centre for Medium-Range Weather Forecasts), served by our own Open-Meteo instance; the chance of rain comes from the ECMWF ensemble. Variables: wind and gusts at 10 m, wind at 850 hPa, relative humidity and temperature at 2 m, rain. Open-Meteo.com (CC BY 4.0).

How it is worked out: wind shift = a change of more than 60° in 6 h or less, with at least 15 km/h before and after; no overnight recovery = peak humidity between 8 pm and 8 am stays below 55 %; useful rain = 2 mm or more in 6 h. The fan opens 18° plus however much the wind varies within ±3 h and reaches 25 km beyond the edge of the fire: one model cell, not a rate of spread. Methodology
Fire radiative power detected each day, in megawatts, and number of hotspots. The magenta bar marks the peak day.
It had gone 10 days without rain (1 mm or more) when it started.
10% of the perimeter overlaps earlier fires recorded since 2016: 6 ha in 2016, 628 ha in 2018, 602 ha in 2023, 191 ha in 2024, 101 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 1,272 ha that had burned before.

This compares size, not location: both shapes are at the same scale, north up, centred on each other.
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.
Inside the perimeter there were about 6.2 hectares of built-up land and about 950 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.

Drag the line to compare the same ground before the fire and after it.
If the day is cloudy, change the date: each satellite passes once a day. In false colour the burnt ground looks brown or red.
On 2 October 2026 the air beside the fire reached 49 µg/m³ of PM2.5. That day averaged 36: 2.4 times the WHO daily guideline (15).
Particles from the Copernicus CAMS model at the centre of the perimeter; these are not measurements in each town. The pale bar is the worst hour, the solid one the daily average.

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.
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.
