Novopskov fire, 25 May 2025 Новопсковський район · Novopskov

Out · last detection 25 May 2025, 09:32 UTC

The fire started on 25 May 2025 in Novopskov, Ukraine, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 107 hectares from satellite imagery, spread across a single municipality.

It is the 847th largest in Luhansk Oblast since 2016 (of 909 with a page). Number 1264 in Ukraine in 2025, of 1359.

The power measured by the satellite is low (11.2 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Frequently asked questions

How long did the Novopskov fire last?
Copernicus dates it between 25 May 2025 and 25 May 2025: 1 day between the first and last image with fire.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 107 hectares (1.1 km²). Official national figures may differ.
Which municipalities burned?
The fire only entered Novopskov (107 ha, 0.1 %).
Did the fire reach a town?
The fire started in Novopskov and came within 15.6 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 29.4 °C, humidity dropped to 20 % and gusts hit 47 km/h. The fire danger index (FWI) reached 30, 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 from the perimeter: the VIIRS detections inside it did not change them. One Suomi-NPP VIIRS detection 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.
