Muling City fire, 15 March 2026 穆棱市 · Muling City

Out · last detection 17 Mar 2026, 05:21 UTC

The fire started on 15 March 2026 in Muling City, China, and satellites saw it burning for 3 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 1,104 hectares from heat detections, spread across a single municipality.

It is the 1496th largest in Heilongjiang Province since 2016 (of 1761 with a page). Number 767 in China in 2026, of 890.

The power measured by the satellite is low (24.2 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 15 days without rain (1 mm or more) when it started. Rain came after the fire: 1.8 mm on 18 Mar.

This area had burned before

4% of the perimeter overlaps earlier fires recorded since 2016: 43 ha in 2021.

How big is it?

It burned the equivalent of 0.7% of the area of London (11 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.

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 · Copernicus

On 17 March 2026 the air beside the fire reached 74 µg/m³ of PM2.5. That day averaged 51: 3.4 times the WHO daily guideline (15).

Frequently asked questions

How long did the Muling City fire last?
GWIS (Copernicus) dates it between 15 March 2026 and 17 March 2026: 3 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 1,104 hectares (11.0 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Muling City (1,114 ha, 0.2 %).
What was the weather like?
During the fire the temperature reached 9.7 °C, humidity dropped to 13 % and gusts hit 44 km/h. The fire danger index (FWI) reached 5, class 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. 16 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.
