Lanxi County fire, October 2026 兰西县 · Lanxi County, Hulan District
Satellites first detected fire on 23 October 2026 in Lanxi County, China. It has been active for 3 days, with 163 heat detections and an area with fire of about 2,128 hectares rebuilt from them, spread across 2 municipalities.
The power measured by the satellite is low (27.8 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…
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.
Is it still active?
Satellites detected fire on 25 Oct 2026, 17:43 UTC. Everything suggests it is still burning. 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.

Area with fire inside each municipality, rebuilt from heat detections (about 14 hectares per VIIRS pixel). An estimate until the official perimeter arrives. 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.

Frequently asked questions
- How long did the Lanxi County fire last?
- According to the heat detections seen by satellite, it burned from 23 October 2026 to 25 October 2026 (3 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 2,128 hectares with fire (21.3 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 2 municipalities: Lanxi County (1,232 ha, 0.5 %); Hulan District (896 ha, 0.4 %).
- Is the Lanxi County fire still active?
- Yes: satellites detected fire on 25 Oct 2026, 17:43 UTC. Check the emergency service for the official status.
- 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.
Report an error
How we know this
- No perimeter yet: the area (≈ 2,128 ha) is estimated by counting VIIRS pixels with fire, about 14 ha each.
- Dates of the first and last VIIRS detection of the cluster. 163 Suomi-NPP VIIRS detections on those dates.
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.
