Fuyu fire, 26 March 2023 Fuyu

Out · last measured on 28 Mar 2023

The fire started on 26 March 2023 in Fuyu, China, and satellites saw it burning for 3 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 1,105 hectares from heat detections, spread across a single municipality.

It is the 698th largest in Jilin Province since 2016 (of 812 with a page). Number 224 in China in 2023, of 280.

We have the GWIS perimeter for this fire, but the VIIRS sensors did not capture it in enough detail: no day-by-day evolution, but the split by municipality is there.

Burnt area inside each municipality, from crossing the GWIS perimeter with administrative boundaries. The distance is from the town centre to the nearest fire: staying a kilometre away does not mean it reached the houses.

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 31 March 2023 the air beside the fire reached 66 µg/m³ of PM2.5. That day averaged 52: 3.5 times the WHO daily guideline (15).

Frequently asked questions

How long did the Fuyu fire last?
GWIS (Copernicus) dates it between 26 March 2023 and 28 March 2023: 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 1,105 hectares (11.0 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Fuyu (1,107 ha, 0.3 %).
What was the weather like?
During the fire the temperature reached 13.6 °C, humidity dropped to 18 % and gusts hit 33 km/h. The fire danger index (FWI) reached 11, 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.

Emergency number: 119

Satellite cross-check

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.

What do you think is wrong?

We will only use your email to reply about this report. Privacy. This is not an emergency service: if there is a fire now, call 119.

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.
