Dawa fire, January 2025 大洼区 · Dawa
The fire started on 6 January 2025 in Dawa, China, and satellites saw it burning for 4 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 1,023 hectares from heat detections, spread across a single municipality.
It is the 51th largest in Liaoning Province since 2016 (of 53 with a page). Number 689 in China in 2025, of 715.
The power measured by the satellite is low (10.4 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 40 days without rain (1 mm or more) when it started.
This area had burned before
29% of the perimeter overlaps earlier fires recorded since 2016: 188 ha in 2020, 213 ha in 2021. Part of it burned more than once, so the yearly figures add up to more than the 301 ha that had burned before.

What happened to each town

1,022 ha0.7 %
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.
The weather day by day
ECMWF ERA5 reanalysis at the fire location, the standard reference for past weather, and the Canadian Fire Weather Index (the same system Copernicus uses), computed by WorldFires from that data. Days after the fire run until the first rain.

The smoke
CAMS · CopernicusOn 12 January 2025 the air beside the fire reached 184 µg/m³ of PM2.5. That day averaged 93: 6.2 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Dawa fire last?
- GWIS (Copernicus) dates it between 6 January 2025 and 9 January 2025: 4 days between the first and last heat detection of the perimeter.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 1,023 hectares (10.2 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Dawa (1,022 ha, 0.7 %).
- What was the weather like?
- During the fire the temperature reached 0.4 °C, humidity dropped to 29 % and gusts hit 44 km/h. The fire danger index (FWI) reached 4, class Very low.
- 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 from the perimeter: the VIIRS detections inside it did not change them. 51 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.
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.
