Marinka fire, 18 August 2025 Мар'їнський район · Marinka, Pokrovsk
The fire started on 18 August 2025 in Marinka, Ukraine, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 155 hectares from satellite imagery, spread across 2 municipalities.
It is the 597th largest in Donetsk Oblast since 2016 (of 1004 with a page). Number 858 in Ukraine in 2025, of 1359.
The power measured by the satellite is low (6.4 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 14 days without rain (1 mm or more) when it started. Rain came after the fire: 1.7 mm on 23 Aug.
This area had burned before
89% of the perimeter overlaps earlier fires recorded since 2016: 51 ha in 2023, 129 ha in 2024. Part of it burned more than once, so the yearly figures add up to more than the 138 ha that had burned before.

Burnt area inside each municipality, from crossing the official 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.

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 20 August 2025 the air beside the fire reached 20 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 Marinka fire last?
- Copernicus dates it between 18 August 2025 and 18 August 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 155 hectares (1.6 km²). Official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Marinka (151 ha, 0.1 %); Pokrovsk (4 ha, 0.0 %).
- Did the fire reach a town?
- The closest fire to a town centre came within 15.4 km of Marinka. 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 31.9 °C, humidity dropped to 19 % and gusts hit 48 km/h. The fire danger index (FWI) reached 44, 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.

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.
