Lutuhyne fire, October 2025 Лутугинський район · Lutuhyne
The fire started on 3 October 2025 in Lutuhyne, Ukraine, and satellites saw it burning for 2 days. Copernicus mapped a burnt perimeter of 218 hectares from satellite imagery, spread across a single municipality.
It is the 408th largest in Luhansk Oblast since 2016 (of 910 with a page). Number 576 in Ukraine in 2025, of 1359.

The weather it burned in
It had gone 12 days without rain (1 mm or more) when it started. Rain came after the fire: 9.9 mm on 5 Oct.

No earlier perimeters overlap this fire since 2016, when the satellite record begins.
What happened to each town
-
219 ha reached on 4 Oct0.2 %
Burnt area inside each municipality, from crossing the official 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.
What burned
- Mixed forest75 %
- Broadleaved forest18 %
- Other natural land6.4 %
Land cover inside the perimeter as reported by Copernicus EFFIS (outside the Corine Land Cover area).
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 5 October 2025 the air beside the fire reached 15 µg/m³ of PM2.5, but no daily average passed the WHO guideline (15).
Particles from the Copernicus CAMS model at the centre of the perimeter; these are not measurements in each town. The pale bar is the worst hour, the solid one the daily average.

Frequently asked questions
- How long did the Lutuhyne fire last?
- Copernicus dates it between 3 October 2025 and 4 October 2025: 2 days between the first and last image with fire.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 218 hectares (2.2 km²). Official national figures may differ.
- Which municipalities burned?
- The fire only entered Lutuhyne (219 ha, 0.2 %).
- Did the fire reach a town?
- The fire started in Lutuhyne and came within 14.4 km of its centre. That is the distance from the perimeter, or the nearest hotspot, to the point marking the centre; it does not mean it entered the houses.
- What was the weather like?
- During the fire the temperature reached 22.4 °C, humidity dropped to 18 % and gusts hit 58 km/h. The fire danger index (FWI) reached 49, class Very high.
- Where does this data come from?
- From the EFFIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Ukraine (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: EFFIS (Copernicus), mapped on satellite imagery.
- Dates from the perimeter: the VIIRS detections inside it did not change them. 9 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 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 ADM2 (Public Domain). 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.
