Jixian County fire, 22 October 2025 集贤县 · Huachuan County, Jixian County, Dongfeng District

Out · last detection 30 Oct 2025, 17:21 UTC

The fire started on 22 October 2025 in Jixian County, China, and satellites saw it burning for 8 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 23,895 hectares from heat detections, spread across 3 municipalities.

Number 5 in China in 2025, of 578.

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.

It had gone 4 days without rain (1 mm or more) when it started. Rain came after the fire: 1.3 mm on 6 Nov.

This area had burned before

34% of the perimeter overlaps earlier fires recorded since 2016: 1,585 ha in 2016, 4,424 ha in 2017, 1,269 ha in 2019, 20 ha in 2022, 1,362 ha in 2023, 2,376 ha in 2024. Part of it burned more than once, so the yearly figures add up to more than the 8,009 ha that had burned before.

How big is it?

It burned the equivalent of 15% of the area of London (239 km² against 1,583 km²).

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 area124 ha
Residents≈ 8,300

Inside the perimeter there were about 124 hectares of built-up land and about 8,300 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 Jixian County fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 22 October 2025 to 29 October 2025 (8 days). The perimeter dates it from 22 October 2025 to 28 October 2025.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 23,895 hectares (239.0 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire entered 3 municipalities: Huachuan County (20,879 ha, 9.3 %); Jixian County (2,690 ha, 1.1 %); Dongfeng District (323 ha, 1.9 %).
What was the weather like?
During the fire the temperature reached 10.0 °C, humidity dropped to 23 % and gusts hit 52 km/h. The fire danger index (FWI) reached 17, class Moderate.
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; 2 polygons grouped in this page.
  • Dates adjusted with the VIIRS detections inside the perimeter, which said 22 October 2025 to 28 October 2025. 636 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 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.
