Dingxiang County fire, 29 October 2026 定襄县 · Dingxiang County
The fire started on 29 October 2026 in Dingxiang County, China, and satellites saw it burning for 5 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 1,004 hectares from heat detections, spread across a single municipality.
It is the 79th largest in Shanxi Province since 2016 (of 81 with a page). Number 1087 in China in 2026, of 1094.
The power measured by the satellite is low (19.8 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.
Compare with…
Is it still active?
No detections since 2 Nov 2026, 05:33 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.

What happened to each town

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.
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 · CopernicusOn 1 November 2026 the air beside the fire reached 86 µg/m³ of PM2.5. That day averaged 43: 2.9 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Dingxiang County fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 29 October 2026 to 2 November 2026 (5 days). The perimeter dates it from 29 October 2026 to 1 November 2026.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 1,004 hectares (10.0 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Dingxiang County (1,006 ha, 1.2 %).
- Is the Dingxiang County fire still active?
- No fire detections since 2 Nov 2026, 05:33 UTC. A lack of detections is not an official extinction.
- What was the weather like?
- During the fire the temperature reached 16.5 °C, humidity dropped to 22 % and gusts hit 34 km/h. The fire danger index (FWI) reached 10, class Low.
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of China (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.

How we know this
- Perimeter: GWIS (Copernicus), rebuilt from heat detections rather than mapped on imagery.
- Dates adjusted with the VIIRS detections inside the perimeter, which said 29 October 2026 to 1 November 2026. 12 Suomi-NPP VIIRS detections on those dates.
- We have not matched this page with any official record.
- Weather: ECMWF IFS model, provisional until the ERA5 reanalysis arrives.
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 ADM3 (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.
