Out · last detection 20 Jul 2024, 06:04 UTC

The fire started on 13 July 2024 in Katangsky Rayon, Russia, and satellites saw it burning for 8 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 5,230 hectares from heat detections, spread across a single municipality.

It is the 229th largest in Irkutsk Oblast since 2016 (of 421 with a page). Number 330 in Russia in 2024, of 557.

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.

Built-up area< 0.1 ha
Residents< 20

Inside 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.

Its twins: fires that started in the same weather

It started with an FWI of 21.7, a minimum humidity of 35% and 4 days without rain. Fires in the area that started in weather like this since 2016: 39.

How a twin is chosen

  • Same area: fires that have already ended, less than 250 km from this one, since 2016.
  • 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.

On 15 July 2024 the air beside the fire reached 170 µg/m³ of PM2.5. That day averaged 120: 8.0 times the WHO daily guideline (15).

Frequently asked questions

How long did the Katangsky Rayon fire last?
GWIS (Copernicus) dates it between 13 July 2024 and 20 July 2024: 8 days between the first and last heat detection of the perimeter.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 5,230 hectares (52.3 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Katangsky Rayon (5,642 ha, 0.0 %).
What was the weather like?
During the fire the temperature reached 29.8 °C, humidity dropped to 26 % and gusts hit 44 km/h. The fire danger index (FWI) reached 26, class 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.
How did the fires that started in similar weather in this area end?
Fires less than 250 km away that started since 2016 with a similar FWI, humidity and dry spell: 39. Their median duration was 13 days and their median area 6,095 ha; 31 % went past 10,000 ha. All of them had rain in the ten days after the end: the first rainy day brought a median of 3.5 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: GWIS (Copernicus), rebuilt from heat detections rather than mapped on imagery.
  • Dates from the perimeter: the VIIRS detections inside it did not change them. 547 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.

How we build fire pages: methodology

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.
