Marinka fire, 5 September 2026 Мар'їнський район · Marinka

Out · last detection 18 Sept 2026, 00:39 UTC

The fire started on 5 September 2026 in Marinka, Ukraine, and satellites saw it burning for 15 days. Copernicus mapped a burnt perimeter of 163 hectares from satellite imagery, spread across a single municipality.

It is the 557th largest in Donetsk Oblast since 2016 (of 1004 with a page). Number 572 in Ukraine in 2026, of 984.

The power measured by the satellite is low (1.3 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

It had gone 8 days without rain (1 mm or more) when it started. Rain came after the fire: 3.5 mm on 22 Sept.

This area had burned before

87% of the perimeter overlaps earlier fires recorded since 2016: 58 ha in 2023, 142 ha in 2024. Part of it burned more than once, so the yearly figures add up to more than the 142 ha that had burned before.

Frequently asked questions

How long did the Marinka fire last?
The official perimeter only gives the start date (5 September 2026). The end comes from the heat detections inside the perimeter: it burned until 19 September 2026 (15 days from 5 September 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 163 hectares (1.6 km²). Official national figures may differ.
Which municipalities burned?
The fire only entered Marinka (164 ha, 0.1 %).
Did the fire reach a town?
The fire started in Marinka and came within 14.9 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 31.9 °C, humidity dropped to 22 % and gusts hit 49 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.

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. One Suomi-NPP VIIRS detection 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.
