Nyurbinsky Ulus fire, 1 August 2026 Nyurbinsky Ulus, Suntarsky Ulus, Mirninsky Ulus
The fire started on 1 August 2026 in Nyurbinsky Ulus, Russia, and satellites saw it burning for 37 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 170,422 hectares from heat detections, spread across 3 municipalities.
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 15th largest in Sakha Republic since 2016 (of 1422 with a page). Number 5 in Russia in 2026, of 418.

- According to the heat detections seen by satellite inside the perimeter, it burned from 1 August 2026 to 6 September 2026 (37 days). The perimeter dates it from 1 August 2026 to 3 September 2026.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 170,422 hectares (1,704.2 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 3 municipalities: Nyurbinsky Ulus (127,753 ha, 2.4 %); Suntarsky Ulus (44,464 ha, 0.8 %); Mirninsky Ulus (12 ha, 0.0 %).
- What was the weather like?
- During the fire the temperature reached 31.5 °C, humidity dropped to 25 % and gusts hit 49 km/h. The fire danger index (FWI) reached 28, 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

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.

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.
