Olyokminsky Ulus fire, 19 June 2024 Olyokminsky Ulus
The fire started on 19 June 2024 in Olyokminsky Ulus, Russia, and satellites saw it burning for 63 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 185,629 hectares from heat detections, spread across a single municipality.
This page is probably a fire complex, not a single fire. GWIS merges into one perimeter the fires that touch over weeks, which in large burning seasons can join dozens of separate fires. The total area is reliable; the origin and dates refer to the whole complex.
It is the 10th largest in Sakha Republic since 2016 (of 1422 with a page). The largest in Russia in 2024, of 560.

Before and after, from space
Drag the line to compare the same ground before the fire and after it.
If the day is cloudy, change the date: each satellite passes once a day. In false colour the burnt ground looks brown or red.
The smoke
CAMS · CopernicusOn 11 July 2024 the air beside the fire reached 1,669 µg/m³ of PM2.5. That day averaged 484: 32 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 Olyokminsky Ulus fire last?
- GWIS (Copernicus) dates it between 19 June 2024 and 20 August 2024: 63 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 185,629 hectares (1,856.3 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Olyokminsky Ulus (194,340 ha, 1.2 %).
- What was the weather like?
- During the fire the temperature reached 32.5 °C, humidity dropped to 24 % and gusts hit 57 km/h. The fire danger index (FWI) reached 31, 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.
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.
Emergency number: 112
Satellite cross-check
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
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.
