Dvorichna fire, 25 August 2024 Дворічанський район · Dvorichna
The fire started on 25 August 2024 in Dvorichna, Ukraine, and satellites saw it burning for 7 days. Copernicus mapped a burnt perimeter of 157 hectares from satellite imagery, spread across a single municipality.
It is the 292th largest in Kharkiv Oblast since 2016 (of 558 with a page). Number 1270 in Ukraine in 2024, of 2092.
The power measured by the satellite is low (9.0 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

12% of the perimeter overlaps earlier fires recorded since 2016: 19 ha in 2023.
What happened to each town

157 ha reached on 25 Aug0.2 %
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 forest97 %
- Mixed forest3.2 %
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 was no noticeable built-up land and almost nobody lived there (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 4 September 2024 the air beside the fire reached 29 µg/m³ of PM2.5. That day averaged 20: 1.3 times the WHO daily 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 Dvorichna fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 25 August 2024 to 31 August 2024 (7 days). The perimeter dates it from 25 August 2024 to 26 August 2024.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 157 hectares (1.6 km²). Official national figures may differ.
- Which municipalities burned?
- The fire only entered Dvorichna (157 ha, 0.2 %).
- Did the fire reach a town?
- The fire started in Dvorichna and came within 4.8 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 34.6 °C, humidity dropped to 20 % and gusts hit 29 km/h. The fire danger index (FWI) reached 42, 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 25 August 2024 to 26 August 2024. 6 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.
