Yasynuvata fire, 10 August 2026 Yasynuvata
The fire started on 10 August 2026 in Yasynuvata, Ukraine, and satellites saw it burning for 10 days. Copernicus mapped a burnt perimeter of 348 hectares from satellite imagery, spread across a single municipality.
It is the 202th largest in Donetsk Oblast since 2016 (of 1004 with a page). Number 231 in Ukraine in 2026, of 984.
The power measured by the satellite is low (4.4 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

The weather it burned in
It had gone 11 days without rain (1 mm or more) when it started.
This area had burned before
75% of the perimeter overlaps earlier fires recorded since 2016: 47 ha in 2022, 54 ha in 2024, 224 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 262 ha that had burned before.

The smoke
CAMS · CopernicusOn 12 August 2026 the air beside the fire reached 23 µg/m³ of PM2.5, but no daily average passed the WHO guideline (15).

Frequently asked questions
- How long did the Yasynuvata fire last?
- The official perimeter only gives the start date (11 August 2026). The end comes from the heat detections inside the perimeter: it burned until 19 August 2026 (10 days from 10 August 2026), the last day with detections before more than 10 days in a row without any, so it is approximate.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 348 hectares (3.5 km²). Official national figures may differ.
- Which municipalities burned?
- The fire only entered Yasynuvata (348 ha, 0.3 %).
- What was the weather like?
- During the fire the temperature reached 32.3 °C, humidity dropped to 18 % and gusts hit 42 km/h. The fire danger index (FWI) reached 32, class High.
- Where does this data come from?
- From the EFFIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Ukraine (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.

How we know this
- Perimeter: EFFIS (Copernicus), mapped on satellite imagery.
- The official perimeter has no end date: the end is the last day with VIIRS detections inside the perimeter before a gap of more than 10 days (150 days at most), so it is approximate. 3 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.
Where this data comes from
The perimeter and land cover come from the Copernicus European Forest Fire Information System (EFFIS), measured on MODIS and Sentinel-2 imagery and published under CC BY 4.0. 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 (Public Domain). The area per municipality is computed by WorldFires by crossing the perimeter with those boundaries, so it may differ slightly from each country’s official figure.
