Krutinsky District fire, 28 April 2023 Bolsheukovsky District, Krutinsky District
The fire started on 28 April 2023 in Krutinsky District, Russia, and satellites saw it burning for 14 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 24,907 hectares from heat detections, spread across 2 municipalities.
It is the 8th largest in Omsk Oblast since 2016 (of 153 with a page). Number 30 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 4 days without rain (1 mm or more) when it started.
This area had burned before
52% of the perimeter overlaps earlier fires recorded since 2016: 1,336 ha in 2018, 4,999 ha in 2020, 7,148 ha in 2021, 1,453 ha in 2022. Part of it burned more than once, so the yearly figures add up to more than the 12,834 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 weather day by day
ECMWF ERA5 reanalysis at the fire location, the standard reference for past weather, and the Canadian Fire Weather Index (the same system Copernicus uses), computed by WorldFires from that data. Days after the fire run until the first rain.

The smoke
CAMS · CopernicusOn 1 May 2023 the air beside the fire reached 54 µg/m³ of PM2.5. That day averaged 22: 1.4 times the WHO daily guideline (15).

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 28 April 2023 to 11 May 2023 (14 days). The perimeter dates it from 29 April 2023 to 6 May 2023.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 24,907 hectares (249.1 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Bolsheukovsky District (22,977 ha, 2.4 %); Krutinsky District (1,766 ha, 0.3 %).
- What was the weather like?
- During the fire the temperature reached 28.6 °C, humidity dropped to 2 % and gusts hit 67 km/h. The fire danger index (FWI) reached 43, 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 29 April 2023 to 6 May 2023. 1,916 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.
