Marinka fire, 9 August 2026 Мар'їнський район · Marinka
The fire started on 9 August 2026 in Marinka, Ukraine, and satellites saw it burning for 10 days. Copernicus mapped a burnt perimeter of 325 hectares from satellite imagery, spread across a single municipality.
It is the 223th largest in Donetsk Oblast since 2016 (of 1004 with a page). Number 258 in Ukraine in 2026, of 984.

The weather it burned in
It had gone 10 days without rain (1 mm or more) when it started. Rain came after the fire: 1.5 mm on 19 Aug.
This area had burned before
1% of the perimeter overlaps earlier fires recorded since 2016: 3 ha in 2024.
What happened to each town

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.

Land cover inside the perimeter as reported by Copernicus EFFIS (outside the Corine Land Cover area).
People and buildings inside the perimeter
GHSL 2025Inside the perimeter there were about 4.8 hectares of built-up land and about 150 residents (GHSL 2025, satellite-based estimate).
This is an estimate on 100 m cells, made from satellite imagery and census data: it does not mean that homes burned or that anyone was harmed. The perimeter also contains land that never burned. The GHSL 2025 epoch is a projection made from 2020 and earlier data.

The smoke
CAMS · CopernicusOn 7 August 2026 the air beside the fire reached 24 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?
- The official perimeter only gives the start date (9 August 2026). The end comes from the heat detections inside the perimeter: it burned until 18 August 2026 (10 days from 9 August 2026), the last day with detections before more than 10 days in a row without any, so it is approximate.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 325 hectares (3.2 km²). Official national figures may differ.
- Which municipalities burned?
- The fire only entered Marinka (326 ha, 0.2 %).
- Did the fire reach a town?
- The fire started in Marinka and came within 2.7 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 32.6 °C, humidity dropped to 19 % and gusts hit 42 km/h. The fire danger index (FWI) reached 35, 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.
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.
- The official perimeter has no end date: the end is the last day with VIIRS detections inside the perimeter before a gap of more than 10 days (150 days at most), so it is approximate. 5 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.
- Built-up area and population come from the JRC Global Human Settlement Layer (epoch 2025, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.
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.
