The fire started on 10 November 2025 in Tieling County, China, and satellites saw it burning for 17 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 5,793 hectares from heat detections, spread across 3 municipalities.

This entry is very probably agricultural burning of stubble or straw that the satellite has merged into a single perimeter, not a wildfire in natural vegetation. We reviewed it by hand: the perimeter comes only from GWIS, lies on densely populated farmland and matches the season when stubble is burnt after the harvest. That is why it is not included in the wildfire rankings.

The power measured by the satellite is low (26.0 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

It had gone one day without rain (1 mm or more) when it started. Rain came after the fire: 1.0 mm on 30 Nov.

This area had burned before

20% of the perimeter overlaps earlier fires recorded since 2016: 148 ha in 2017, 129 ha in 2018, 995 ha in 2020. Part of it burned more than once, so the yearly figures add up to more than the 1,179 ha that had burned before.

How big is it?

It burned the equivalent of 3.7% of the area of London (58 km² against 1,583 km²).

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.

How we know this

Perimeter: GWIS (Copernicus), rebuilt from heat detections rather than mapped on imagery; 3 polygons grouped in this page.
Dates adjusted with the VIIRS detections inside the perimeter, which said 12 November 2025 to 23 November 2025. 152 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.
Probably a vegetation burn: not counted in the totals.

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.
