Mappi fire, 14 October 2026 Mappi

Out · last detection 14 Oct 2026, 04:17 UTC

Satellites first detected fire on 14 October 2026 in Mappi, Indonesia. It has been active for 1 day, with 174 heat detections and an area with fire of about 2,156 hectares rebuilt from them, spread across a single municipality.

GWIS (Copernicus) has not yet published the perimeter of this fire. It rebuilds it from hotspots, which can take several days, and it does not always arrive. For now the area is the one rebuilt from heat detections (about 14 hectares per pixel). If the perimeter arrives, this page picks it up on its own and keeps the same address.

Area with fire inside each municipality, rebuilt from heat detections (about 14 hectares per VIIRS pixel). An estimate until the official perimeter arrives. 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 · Copernicus

On 13 October 2026 the air beside the fire reached 224 µg/m³ of PM2.5. That day averaged 128: 8.5 times the WHO daily guideline (15).

Frequently asked questions

How long did the Mappi fire last?
According to the heat detections seen by satellite, it burned from 14 October 2026 to 14 October 2026 (1 day between the first and the last detection). There is no perimeter yet to date it.
How much area did it burn?
There is no perimeter yet. Heat detections rebuild about 2,156 hectares with fire (21.6 km²), a rough figure; GWIS will give its own when it publishes the perimeter, which can take several days.
Which municipalities burned?
The fire only entered Mappi (2,002 ha, 0.1 %).
Is the Mappi fire still active?
No fire detections since 14 Oct 2026, 04:17 UTC. A lack of detections is not an official extinction.
What was the weather like?
During the fire the temperature reached 33.5 °C, humidity dropped to 48 % and gusts hit 32 km/h. The fire danger index (FWI) reached 15, class Moderate.
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.

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.

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.
