Srednekolymsky Ulus fire, 17 June 2019 Srednekolymsky Ulus
Out · last detection 2 Jul 2019, 02:36 UTC
The fire started on 17 June 2019 in Srednekolymsky Ulus, Russia, and satellites saw it burning for 16 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 4,497 hectares from heat detections, spread across a single municipality.
It is the 944th largest in Sakha Republic since 2016 (of 1347 with a page). Number 384 in Russia in 2019, of 610.

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.

Residents< 20
Inside the perimeter there was no noticeable built-up land and almost nobody lived there (GHSL 2020, 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.

How a twin is chosen
- Same area: fires that have already ended, less than 250 km from this one, since 2019.
- 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.

Frequently asked questions
- How long did the Srednekolymsky Ulus fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 17 June 2019 to 2 July 2019 (16 days). The perimeter dates it from 19 June 2019 to 27 June 2019.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 4,497 hectares (45.0 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Srednekolymsky Ulus (4,538 ha, 0.0 %).
- What was the weather like?
- During the fire the temperature reached 26.6 °C, humidity dropped to 24 % and gusts hit 51 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 2019 with a similar FWI, humidity and dry spell: 20. Their median duration was 11 days and their median area 5,581 ha; 30 % 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 10.5 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.
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 19 June 2019 to 27 June 2019. 450 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 2020, 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.
