Orikhiv fire, 16 July 2025 Оріхівський район · Orikhiv

Out · last detection 16 Jul 2025, 09:57 UTC

The fire started on 16 July 2025 in Orikhiv, Ukraine, and satellites saw it burning for 3 days. Copernicus mapped a burnt perimeter of 208 hectares from satellite imagery, spread across a single municipality.

It is the 190th largest in Zaporizhzhia Oblast since 2016 (of 490 with a page). Number 608 in Ukraine in 2025, of 1359.

The power measured by the satellite is low (3.9 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

It had gone 13 days without rain (1 mm or more) when it started. Rain came after the fire: 3.0 mm on 23 Jul.

This area had burned before

51% of the perimeter overlaps earlier fires recorded since 2016: 64 ha in 2023, 64 ha in 2024. Part of it burned more than once, so the yearly figures add up to more than the 106 ha that had burned before.

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.

People and buildings inside the perimeter

GHSL 2025
Built-up area5.1 ha
Residents≈ 150

Inside the perimeter there were about 5.1 hectares of built-up land and about 150 residents (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.

Frequently asked questions

How long did the Orikhiv fire last?
Copernicus dates it between 16 July 2025 and 18 July 2025: 3 days between the first and last image with fire.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 208 hectares (2.1 km²). Official national figures may differ.
Which municipalities burned?
The fire only entered Orikhiv (208 ha, 0.1 %).
Did the fire reach a town?
The fire started in Orikhiv and came within 31.5 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 33.3 °C, humidity dropped to 31 % and gusts hit 36 km/h. The fire danger index (FWI) reached 24, 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.
  • 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.
