Out · last measured on 13 Aug 2026

The fire started on 12 April 2026 in Kreminna, Ukraine, and satellites saw it burning for 124 days. Copernicus mapped a burnt perimeter of 117 hectares from satellite imagery, spread across a single municipality.

It is the 780th largest in Luhansk Oblast since 2016 (of 909 with a page). Number 823 in Ukraine in 2026, of 984.

We have the Copernicus perimeter for this fire, but not yet its hotspots: NASA publishes the yearly hotspot archive only once the year closes. The page picks it up automatically when it is available.

It had gone one day without rain (1 mm or more) when it started.

This area had burned before

81% of the perimeter overlaps earlier fires recorded since 2016: 34 ha in 2022, 11 ha in 2023, 70 ha in 2024, 4 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 95 ha that had burned before.

Frequently asked questions

How long did the Kreminna fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 12 April 2026 to 13 August 2026 (124 days). The perimeter dates it from 12 April 2026 to 12 April 2026.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 117 hectares (1.2 km²). Official national figures may differ.
Which municipalities burned?
The fire only entered Kreminna (117 ha, 0.1 %).
Did the fire reach a town?
The fire started in Kreminna and came within 30.6 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 35.5 °C, humidity dropped to 14 % and gusts hit 69 km/h. The fire danger index (FWI) reached 32, 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.
  • Dates adjusted with the VIIRS detections inside the perimeter, which said 12 April 2026 to 12 April 2026. No 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.
