Out · last detection 18 Aug 2024, 05:19 UTC
The fire started on 29 July 2024 in Киренский район, Russia, and satellites saw it burning for 21 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 5,570 hectares from heat detections, spread across a single municipality.
It is the 212th largest in Irkutsk Oblast since 2016 (of 421 with a page). Number 309 in Russia in 2024, of 557.

Satellites pass a few times a day and cloud or smoke can hide the fire: a lack of detections is not an official extinction. Each country’s emergency service declares a fire contained or out.

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 2025Built-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.

Frequently asked questions
- How long did the Киренский район fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 29 July 2024 to 18 August 2024 (21 days). The perimeter dates it from 5 August 2024 to 18 August 2024.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 5,570 hectares (55.7 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Киренский район (5,679 ha, 0.1 %).
- What was the weather like?
- During the fire the temperature reached 30.5 °C, humidity dropped to 30 % and gusts hit 41 km/h. The fire danger index (FWI) reached 18, class Moderate.
- 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.
Report an error
How we know this
- Perimeter: GWIS (Copernicus), rebuilt from heat detections rather than mapped on imagery.
- Dates adjusted with the VIIRS detections inside the perimeter, which said 5 August 2024 to 18 August 2024. 741 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.
