How long did the Seredyna-Buda fire last?

According to the heat detections seen by satellite inside the perimeter, it burned from 30 August 2024 to 8 September 2024 (10 days). The perimeter dates it from 30 August 2024 to 1 September 2024.

How much area did it burn?

The perimeter Copernicus measured from satellite imagery is 936 hectares (9.4 km²). Official national figures may differ.

Which municipalities burned?

The fire only entered Seredyna-Buda (794 ha, 0.7 %).

Did the fire reach a town?

The fire started in Seredyna-Buda and came within 16.0 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 29.9 °C, humidity dropped to 28 % and gusts hit 45 km/h. The fire danger index (FWI) reached 36, 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.

Inside 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.

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 30 August 2024 to 1 September 2024. 115 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.

How we build fire pages: methodology ›

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.
