Taobei District fire, 18 March 2026 洮北区 · Zhenlai County, Taobei District

Out · last detection 28 Mar 2026, 05:15 UTC

The fire started on 18 March 2026 in Taobei District, China, and satellites saw it burning for 11 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,858 hectares from heat detections, spread across 2 municipalities.

Number 266 in China in 2026, of 1105.

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 (21.1 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 14 days without rain (1 mm or more) when it started. Rain came after the fire: 5.1 mm on 3 Apr.

This area had burned before

43% of the perimeter overlaps earlier fires recorded since 2016: 688 ha in 2016, 286 ha in 2018, 88 ha in 2019, 300 ha in 2020, 13 ha in 2021, 316 ha in 2024, 103 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 1,218 ha that had burned before.

How big is it?

10 km
It burned the equivalent of 1.8% of the area of London (29 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 area12 ha
Residents≈ 150

Inside the perimeter there were about 12 hectares of built-up land and about 150 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.

How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 2,858 hectares (28.6 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire entered 2 municipalities: Zhenlai County (1,921 ha, 0.4 %); Taobei District (931 ha, 0.5 %).
What was the weather like?
During the fire the temperature reached 17.3 °C, humidity dropped to 9 % and gusts hit 59 km/h. The fire danger index (FWI) reached 16, 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.
  • Dates adjusted with the VIIRS detections inside the perimeter, which said 18 March 2026 to 25 March 2026. 62 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.
