How long did the Lutuhyne fire last?

Copernicus dates it between 11 July 2025 and 11 July 2025: 1 day between the first and last image with fire.

How much area did it burn?

The perimeter Copernicus measured from satellite imagery is 1,314 hectares (13.1 km²). Official national figures may differ.

Which municipalities burned?

The fire entered 3 municipalities: Lutuhyne (1,096 ha, 1.0 %); Sorokyne (212 ha, 0.2 %); Dovzhansk (2 ha, 0.0 %).

Did the fire reach a town?

The closest fire to a town centre came within 20.5 km of Dovzhansk. That is the distance to the perimeter or nearest hotspot; it does not mean it entered the houses.

What was the weather like?

During the fire the temperature reached 35.5 °C, humidity dropped to 20 % and gusts hit 44 km/h. The fire danger index (FWI) reached 37, class 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.

Lutuhyne fire, 11 July 2025 Лутугинський район · Lutuhyne, Sorokyne, Dovzhansk

Out · last detection 11 Jul 2025, 11:32 UTC

The fire started on 11 July 2025 in Lutuhyne, Ukraine, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 1,314 hectares from satellite imagery, spread across 3 municipalities.

It is the 50th largest in Luhansk Oblast since 2016 (of 909 with a page). Number 39 in Ukraine in 2025, of 1359.

The power measured by the satellite is low (17.3 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

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 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.
