Frequently asked questions

How long did the Holo Prystan fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 6 July 2023 to 11 July 2023 (6 days). The perimeter dates it from 6 July 2023 to 7 July 2023.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 2,323 hectares (23.2 km²). Official national figures may differ.
Which municipalities burned?
The fire only entered Holo Prystan (2,325 ha, 1.1 %).
Did the fire reach a town?
The fire started in Holo Prystan and came within 25.0 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 36.0 °C, humidity dropped to 28 % and gusts hit 55 km/h. The fire danger index (FWI) reached 25, 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 6 July 2023 to 7 July 2023. 95 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.
