Krutinsky District fire, 27 April 2023 Krutinsky District, Abatsky District
The fire started on 27 April 2023 in Krutinsky District, Russia, and satellites saw it burning for 25 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 26,557 hectares from heat detections, spread across 2 municipalities.
It is the 6th largest in Omsk Oblast since 2016 (of 153 with a page). Number 27 in Russia in 2023, of 450.

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. Rain came after the fire: 2.8 mm on 25 May.
This area had burned before
68% of the perimeter overlaps earlier fires recorded since 2016: 1,312 ha in 2018, 414 ha in 2019, 3,801 ha in 2020, 10,326 ha in 2021, 8,195 ha in 2022. Part of it burned more than once, so the yearly figures add up to more than the 18,106 ha that had burned before.

Burnt area inside each municipality, from crossing the GWIS 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.
People and buildings inside the perimeter
GHSL 2025Inside the perimeter there was no noticeable built-up land and almost nobody lived there (GHSL 2025, satellite-based estimate).
This is an estimate on 100 m cells, made from satellite imagery and census data: it does not mean that homes burned or that anyone was harmed. The perimeter also contains land that never burned. The GHSL 2025 epoch is a projection made from 2020 and earlier data.

The smoke
CAMS · CopernicusOn 11 May 2023 the air beside the fire reached 72 µg/m³ of PM2.5. That day averaged 36: 2.4 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 Krutinsky District fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 27 April 2023 to 21 May 2023 (25 days). The perimeter dates it from 28 April 2023 to 21 May 2023.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 26,557 hectares (265.6 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Krutinsky District (24,093 ha, 4.2 %); Abatsky District (2,583 ha, 0.6 %).
- What was the weather like?
- During the fire the temperature reached 28.4 °C, humidity dropped to 4 % and gusts hit 66 km/h. The fire danger index (FWI) reached 42, class Very high.
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Russia (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.

How we know this
- Perimeter: GWIS (Copernicus), rebuilt from heat detections rather than mapped on imagery; 3 polygons grouped in this page.
- Dates adjusted with the VIIRS detections inside the perimeter, which said 28 April 2023 to 21 May 2023. 1,511 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.
- Built-up area and population come from the JRC Global Human Settlement Layer (epoch 2025, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.
Where this data comes from
The perimeter comes from the Copernicus Global Wildfire Information System (GWIS), which rebuilds it from MODIS and VIIRS heat detections and publishes it under CC BY 4.0. It is not measured on imagery as in Europe, so it is an estimate. 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 (Open Data Commons Open Database License 1.0). The area per municipality is computed by WorldFires by crossing the perimeter with those boundaries, so it may differ from each country’s official figure.
