Sorokyne fire, June 2024 Sorokyne
Out · last detection 7 Jun 2024, 23:24 UTC
The fire started on 3 June 2024 in Sorokyne, Ukraine, and satellites saw it burning for 5 days. Copernicus mapped a burnt perimeter of 201 hectares from satellite imagery, spread across a single municipality.
It is the 443th largest in Luhansk Oblast since 2016 (of 909 with a page). Number 956 in Ukraine in 2024, of 2092.
The power measured by the satellite is low (6.1 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

How a twin is chosen
- Same area: fires that have already ended, less than 250 km from this one, since 2016.
- Same start: we compare the FWI on the first day, the minimum humidity that day and the run of days without rain before it. The slider sets how much they may differ.
- Only pages with final weather data (ERA5 reanalysis) calculated in the same way as this fire’s; agricultural and grass burns and pages with data under review are left out.
- Fires burning at the same time as this one (a week before or after) are left out: they share the same spell of weather and do not count as a precedent.
- They are sorted by similarity, and the outlines of the first five are drawn.

Frequently asked questions
- How long did the Sorokyne fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 3 June 2024 to 7 June 2024 (5 days). The perimeter dates it from 3 June 2024 to 5 June 2024.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 201 hectares (2.0 km²). Official national figures may differ.
- Which municipalities burned?
- The fire only entered Sorokyne (201 ha, 0.1 %).
- What was the weather like?
- During the fire the temperature reached 33.3 °C, humidity dropped to 29 % and gusts hit 52 km/h. The fire danger index (FWI) reached 60, class Extreme.
- 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.
- How did the fires that started in similar weather in this area end?
- Fires less than 250 km away that started since 2016 with a similar FWI, humidity and dry spell: 30. Their median duration was 2 days and their median area 218 ha; 10 % went past 1,000 ha. In 10 of 30, not even 1 mm fell in the ten days after the end: they went out without rain. In the rest, the first rainy day brought a median of 2.6 mm.
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.
Report an error
How we know this
- Perimeter: EFFIS (Copernicus), mapped on satellite imagery.
- Dates adjusted with the VIIRS detections inside the perimeter, which said 3 June 2024 to 5 June 2024. 7 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.
