Kobyaysky Ulus fire, 19 July 2019 Kobyaysky Ulus

Out · last detection 2 Aug 2019, 18:22 UTC

The fire started on 19 July 2019 in Kobyaysky Ulus, Russia, and satellites saw it burning for 15 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 3,107 hectares from heat detections, spread across a single municipality.

It is the 1380th largest in Sakha Republic since 2016 (of 1422 with a page). Number 590 in Russia in 2019, of 613.

Frequently asked questions

How long did the Kobyaysky Ulus fire last?
GWIS (Copernicus) dates it between 19 July 2019 and 2 August 2019: 15 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 3,107 hectares (31.1 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Kobyaysky Ulus (2,994 ha, 0.0 %).
What was the weather like?
During the fire the temperature reached 29.4 °C, humidity dropped to 26 % and gusts hit 55 km/h. The fire danger index (FWI) reached 20, 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.

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.

What do you think is wrong?

We will only use your email to reply about this report. Privacy. This is not an emergency service: if there is a fire now, call 112.

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.
