Kiliia fire, February 2022 Кілійський район · Kiliia

Out · last detection 5 Feb 2022, 23:19 UTC

The fire started on 5 February 2022 in Kiliia, Ukraine, and satellites saw it burning for 2 days. Copernicus mapped a burnt perimeter of 951 hectares from satellite imagery, spread across a single municipality.

This entry is probably an agricultural burn of stubble, meadow or peatland, not a wildfire. Before the war, stubble and meadows in Ukraine were burnt every spring and autumn, and the fire often got out of hand. This is our assumption, based on the time of year, ground with almost no woodland and the lack of news about this fire; it is not confirmed. That is why it is left out of the wildfire rankings.

The power measured by the satellite is low (4.9 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Its twins: fires that started in the same weather

It started with an FWI of 0.4, a minimum humidity of 57% and 2 days without rain. Fires in the area that started in weather like this since 2019: 25.

It was 5.2 times larger than the median of its twins and lasted 2 days, against 2 days.

Only 3 of its 25 twins burned more. The weather on the first day does not explain everything: the wind in the following days, the fuel and the firefighting also count. In 3 of 25, not even 1 mm fell in the ten days after the end: they went out without rain. In the rest, the first rainy day brought a median of 2.2 mm.

How a twin is chosen

  • Same area: fires that have already ended, less than 250 km from this one, since 2019.
  • Same start: we compare the FWI on the first day, the minimum humidity that day and the run of days without rain before it. The slider sets how much they may differ.
  • Only pages with final weather data (ERA5 reanalysis) calculated in the same way as this fire’s; agricultural and grass burns and pages with data under review are left out.
  • Fires burning at the same time as this one (a week before or after) are left out: they share the same spell of weather and do not count as a precedent.
  • They are sorted by similarity, and the outlines of the first five are drawn.

Frequently asked questions

How long did the Kiliia fire last?
Copernicus dates it between 5 February 2022 and 6 February 2022: 2 days between the first and last image with fire.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 951 hectares (9.5 km²). Official national figures may differ.
Which municipalities burned?
The fire only entered Kiliia (950 ha, 0.7 %).
Did the fire reach a town?
The fire started in Kiliia and came within 4.1 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 7.6 °C, humidity dropped to 52 % and gusts hit 33 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.
How did the fires that started in similar weather in this area end?
Fires less than 250 km away that started since 2019 with a similar FWI, humidity and dry spell: 25. Their median duration was 2 days and their median area 184 ha; 12 % went past 1,000 ha. Only 3 of its 25 twins burned more. The weather on the first day does not explain everything: the wind in the following days, the fuel and the firefighting also count. In 3 of 25, not even 1 mm fell in the ten days after the end: they went out without rain. In the rest, the first rainy day brought a median of 2.2 mm.

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; 2 polygons grouped in this page.
  • 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.
  • Probably a vegetation burn: not counted in the totals.

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.
