Eupen fire, May 2023 Eupen
The fire started on 30 May 2023 in Eupen, Belgium, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 151 hectares from satellite imagery, spread across a single municipality.
The only fire in Belgium with a page in 2023.
The power measured by the satellite is low (11.8 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 7 days without rain (1 mm or more) when it started. Rain came after the fire: 3.7 mm on 7 Jun.
This area had burned before
No earlier perimeters overlap this fire since 2016, when the satellite record begins.

The smoke
CAMS · CopernicusOn 2 June 2023 the air beside the fire reached 19 µg/m³ of PM2.5, but no daily average passed the WHO guideline (15).

Frequently asked questions
- How long did the Eupen fire last?
- Copernicus dates it between 30 May 2023 and 30 May 2023: 1 day between the first and last image with fire.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 151 hectares (1.5 km²). Official national figures may differ.
- Which municipalities burned?
- The fire only entered Eupen (150 ha, 1.6 %).
- What was the weather like?
- During the fire the temperature reached 16.4 °C, humidity dropped to 50 % and gusts hit 40 km/h. The fire danger index (FWI) reached 8, class Low.
- Where does this data come from?
- From the EFFIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Belgium (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: 112

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.

Where this data comes from
The perimeter and land cover come from the Copernicus European Forest Fire Information System (EFFIS), measured on MODIS and Sentinel-2 imagery and published under CC BY 4.0. 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 ADM4 (Creative Commons Attribution 4.0 International (CC BY 4.0)). The area per municipality is computed by WorldFires by crossing the perimeter with those boundaries, so it may differ slightly from each country’s official figure.
