How long did the Khust fire last?

Copernicus dates it between 14 March 2022 and 14 March 2022: 1 day between the first and last image with fire.

How much area did it burn?

The perimeter Copernicus measured from satellite imagery is 191 hectares (1.9 km²). Official national figures may differ.

Which municipalities burned?

The fire only entered Khust (190 ha, 0.2 %).

Did the fire reach a town?

The closest fire to a town centre came within 25.2 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 10.7 °C, humidity dropped to 31 % and gusts hit 18 km/h. The fire danger index (FWI) reached 2, 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.

The fire started on 14 March 2022 in Khust, Ukraine, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 191 hectares from satellite imagery, spread across a single municipality.

It is the 10th largest in Zakarpattia Oblast since 2016 (of 24 with a page). Number 273 in Ukraine in 2022, of 531.

The power measured by the satellite is low (5.7 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

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.
