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.
What burned
- Coniferous forest70 %
- Mixed forest30 %
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 23 August 2024 the air beside the fire reached 16 µg/m³ of PM2.5, but no daily average passed the WHO guideline (15).

Frequently asked questions
- How long did the Popasna fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 19 August 2024 to 27 August 2024 (9 days). The perimeter dates it from 19 August 2024 to 21 August 2024.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 769 hectares (7.7 km²). Official national figures may differ.
- Which municipalities burned?
- The fire only entered Popasna (770 ha, 0.4 %).
- Did the fire reach a town?
- The fire started in Popasna and came within 24.7 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 34.9 °C, humidity dropped to 18 % and gusts hit 40 km/h. The fire danger index (FWI) reached 43, 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.
- Dates adjusted with the VIIRS detections inside the perimeter, which said 19 August 2024 to 21 August 2024. 96 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.
