Khust fire, 1 March 2026 Хуст · Khust
The fire started on 1 March 2026 in Khust, Ukraine, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 171 hectares from satellite imagery, spread across a single municipality.
It is the 13th largest in Zakarpattia Oblast since 2016 (of 24 with a page). Number 536 in Ukraine in 2026, of 984.
The power measured by the satellite is low (12.2 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Where it burned
How it evolved, day by day
Fire radiative power detected each day, in megawatts, and number of hotspots. The magenta bar marks the peak day.
The weather it burned in
It had gone 3 days without rain (1 mm or more) when it started.
This area had burned before
26% of the perimeter overlaps earlier fires recorded since 2016: 44 ha in 2022.
What happened to each town
-
170 ha reached on 1 Mar0.1 %
Burnt area inside each municipality, from crossing the official perimeter with administrative boundaries. The distance is from the town centre to the nearest fire: staying a kilometre away does not mean it reached the houses.
What burned
- Agricultural areas55 %
- Mixed forest27 %
- Broadleaved forest18 %
Land cover inside the perimeter as reported by Copernicus EFFIS (outside the Corine Land Cover area).
The weather day by day
ECMWF ERA5 reanalysis at the fire location, the standard reference for past weather, and the Canadian Fire Weather Index (the same system Copernicus uses), computed by WorldFires from that data. Days after the fire run until the first rain.

The smoke
CAMS · CopernicusOn 2 March 2026 the air beside the fire reached 31 µg/m³ of PM2.5. That day averaged 19: 1.2 times the WHO daily guideline (15).
Particles from the Copernicus CAMS model at the centre of the perimeter; these are not measurements in each town. The pale bar is the worst hour, the solid one the daily average.

Frequently asked questions
- How long did the Khust fire last?
- Copernicus dates it between 1 March 2026 and 1 March 2026: 1 day between the first and last image with fire.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 171 hectares (1.7 km²). Official national figures may differ.
- Which municipalities burned?
- The fire only entered Khust (170 ha, 0.1 %).
- Did the fire reach a town?
- The closest fire to a town centre came within 21.3 km of Khust. That is the distance to the perimeter or nearest hotspot; 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 38 % and gusts hit 14 km/h. The fire danger index (FWI) reached 1, class Very 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.

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.
