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.

Burnt area inside each municipality, from crossing the official perimeter with administrative boundaries. The distance runs from the point marking the centre of each area to the nearest fire: staying a kilometre away does not mean it reached the houses.

It was 1.5 times larger than the median of its twins and lasted 1 day, against 2 days.

Only 16 of its 48 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 10 of 48, 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 3.0 mm.

It was considered over on 12 Oct, and on 16 Oct 2.3 mm fell. We do not know whether the rain or the firefighters put it out. Twins with rain when they ended: 38 of 48, with a median of 3.0 mm.

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.

The smoke

CAMS · Copernicus

On 14 October 2023 the air beside the fire reached 23 µg/m³ of PM2.5. That day averaged 20: 1.4 times the WHO daily guideline (15).

Frequently asked questions

How long did the Antratsyt fire last?
Copernicus dates it between 12 October 2023 and 12 October 2023: 1 day between the first and last image with fire.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 319 hectares (3.2 km²). Official national figures may differ.
Which municipalities burned?
The fire only entered Antratsyt (318 ha, 0.1 %).
Did the fire reach a town?
The fire started in Antratsyt and came within 25.0 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 12.2 °C, humidity dropped to 28 % and gusts hit 38 km/h. The fire danger index (FWI) reached 19, 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: 48. Their median duration was 2 days and their median area 208 ha; 8 % went past 1,000 ha. Only 16 of its 48 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 10 of 48, 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 3.0 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.

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.
