Dubrovytsia fire, 21 October 2021 Дубровицький район · Dubrovytsia

Out · last measured on 21 Oct 2021

The fire started on 21 October 2021 in Dubrovytsia, Ukraine, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 114 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.

We have the Copernicus perimeter for this fire, but the VIIRS sensors did not capture it in enough detail: no day-by-day evolution, but the split by municipality is there.

How a twin is chosen

  • Same area: fires that have already ended, less than 250 km from this one, since 2020.
  • 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 Dubrovytsia fire last?
Copernicus dates it between 21 October 2021 and 21 October 2021: 1 day between the first and last image with fire.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 114 hectares (1.1 km²). Official national figures may differ.
Which municipalities burned?
The fire only entered Dubrovytsia (114 ha, 0.1 %).
Did the fire reach a town?
The fire started in Dubrovytsia and came within 11.9 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 18.8 °C, humidity dropped to 41 % and gusts hit 59 km/h. The fire danger index (FWI) reached 18, class Moderate.
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 2020 with a similar FWI, humidity and dry spell: 72. Their median duration was 2 days and their median area 183 ha; 11 % went past 1,000 ha. In 14 of 72, 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 3.1 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.
  • Dates from the perimeter: the VIIRS detections inside it did not change them. No 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.
  • 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.
