Hulan District fire, 22 October 2026 呼兰区 · Hulan District
The fire started on 22 October 2026 in Hulan District, China, and satellites saw it burning for 10 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 1,766 hectares from heat detections, spread across a single municipality.
It is the 784th largest in Heilongjiang Province since 2016 (of 1915 with a page). Number 513 in China in 2026, of 1094.
The power measured by the satellite is low (25.4 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Where it burned
How it evolved, day by day
Fire radiative power detected each day, in megawatts, and number of hotspots. The magenta bar marks the peak day.
The weather it burned in
It had gone 3 days without rain (1 mm or more) when it started.
This area had burned before
79% of the perimeter overlaps earlier fires recorded since 2016: 187 ha in 2017, 530 ha in 2022, 1,210 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 1,392 ha that had burned before.

What happened to each town
-
1,762 ha reached on 22 Oct0.8 %
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 2025Inside the perimeter there were about 29 hectares of built-up land and about 2,900 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.

The smoke
CAMS · CopernicusOn 25 October 2026 the air beside the fire reached 43 µg/m³ of PM2.5. That day averaged 26: 1.7 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Hulan District fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 22 October 2026 to 31 October 2026 (10 days). The perimeter dates it from 22 October 2026 to 26 October 2026.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 1,766 hectares (17.7 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Hulan District (1,762 ha, 0.8 %).
- Is the Hulan District fire still active?
- No fire detections since 31 Oct 2026, 04:32 UTC. A lack of detections is not an official extinction.
- What was the weather like?
- During the fire the temperature reached 15.0 °C, humidity dropped to 22 % and gusts hit 58 km/h. The fire danger index (FWI) reached 14, 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 22 October 2026 to 26 October 2026. 27 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.
- 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.
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.
