Horokhiv fire, March 2026 Горохівський район · Horokhiv

Out · last detection 15 Mar 2026, 11:06 UTC

The fire started on 15 March 2026 in Horokhiv, Ukraine, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 161 hectares from satellite imagery, spread across a single municipality.

It is the 37th largest in Volyn Oblast since 2016 (of 71 with a page). Number 583 in Ukraine in 2026, of 984.

The power measured by the satellite is low (8.1 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 17 days without rain (1 mm or more) when it started.

This area had burned before

27% of the perimeter overlaps earlier fires recorded since 2016: 41 ha in 2022, 23 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 44 ha that had burned before.

Frequently asked questions

How long did the Horokhiv fire last?
The official perimeter only gives the start date (15 March 2026). The end comes from the heat detections inside the perimeter: it burned until 15 March 2026 (1 day from 15 March 2026), the last day with detections before more than 10 days in a row without any, so it is approximate.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 161 hectares (1.6 km²). Official national figures may differ.
Which municipalities burned?
The fire only entered Horokhiv (161 ha, 0.1 %).
Did the fire reach a town?
The fire started in Horokhiv and came within 5.5 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 14.0 °C, humidity dropped to 33 % and gusts hit 43 km/h. The fire danger index (FWI) reached 11, class Low.
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.
  • The official perimeter has no end date: the end is the last day with VIIRS detections inside the perimeter before a gap of more than 10 days (150 days at most), so it is approximate. 2 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.

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.
