Shushtar fire, October 2026
Shushtar, Shush, Ahvaz
Out · last detection 4 Nov 2026, 22:22 UTC
Satellites first detected fire on 31 October 2026 in Shushtar, Iran. It was active for 5 days, with 82 heat detections and an area with fire of about 1,050 hectares rebuilt from them, spread across 4 municipalities.
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.
The power measured by the satellite is low (16.4 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Weather and FWI computed from the forecast (provisional until ERA5 arrives)
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.

⬇ Download CSVTimes in UTC. Each detection is a 375 m pixel: a large fire yields hundreds per pass.
According to the heat detections seen by satellite, it burned from 31 October 2026 to 4 November 2026 (5 days 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 1,050 hectares with fire (10.5 km²), a rough figure; GWIS will give its own when it publishes the perimeter, which can take several days.
Which municipalities burned?
The fire entered 4 municipalities: Shushtar (434 ha, 0.2 %); Shush (420 ha, 0.1 %); Ahvaz (112 ha, 0.0 %); Bavi (84 ha, 0.1 %).
Is the Shushtar fire still active?
No fire detections since 4 Nov 2026, 22:22 UTC. A lack of detections is not an official extinction.
What was the weather like?
During the fire the temperature reached 35.5 °C, humidity dropped to 18 % and gusts hit 45 km/h. The fire danger index (FWI) reached 49, class Very high.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Iran (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.
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.

No perimeter yet: the area (≈ 1,050 ha) is estimated by counting VIIRS pixels with fire, about 14 ha each.
Dates of the first and last VIIRS detection of the cluster. 82 Suomi-NPP VIIRS detections on those dates.
Weather: ECMWF IFS model, provisional until the ERA5 reanalysis arrives.
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 (Open Data Commons Open Database License 1.0). 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.
