Satellites first detected fire on 1 October 2026 in Yasynuvata, Ukraine. It was active for 13 days, with 17 heat detections and an area with fire of about 238 hectares rebuilt from them, spread across 2 municipalities.
Estimated from hotspots: no perimeter has been published yet.
This is an estimate from the VIIRS pixels that saw fire. It will change when the perimeter is published.
1 Oct 2026 to 13 Oct 2026: first and last day with fire on the page.
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.
First day with fire seen by the satellites or the perimeter.
No official record is matched to this page, so the alert time and the cause are not known here.
VIIRS detections at 375 m. Most intense hotspot: 34 MW.
There is no official record to compare with. Each hotspot is a pixel detected in one satellite pass, not a separate fire.
Total radiative power on 8 October 2026; hotspots that day: 5.
Fire radiative power (FRP) measures the energy the fire gives off when the satellite passes. Added up by day, it compares intensity, not area.
Fire Weather Index (Canadian system) computed by WorldFires for the day the fire started. Consecutive days without rain before: 0.
This is an index computed from weather model data, not a measurement of the fire nor an official warning. Danger warnings are issued by each country’s authority. Emergency number and official warnings
High of 25.5 °C and minimum humidity of 31% on 12 October 2026; gusts of 44 km/h on 2 October 2026.
These are model values for a cell of about 25 km, not from a weather station: they may differ from what was measured on the ground.
This page’s change log has been kept since 24 October 2026: every night what it publishes is compared and the difference is logged. Anything earlier is reconstructed from each source’s date and marked as reconstructed.
Every night a snapshot of what the page shows is saved. If anything changes, it appears in the list as a log entry.
A version keeps the area, dates, name and official record; the area as it was logged (changes under 2% are not logged). The map, hotspots and weather always show today’s data.

Copernicus has not yet published the burnt perimeter, which takes a few days to measure on satellite imagery. For now the area is the one rebuilt from heat detections (about 14 hectares per pixel). When the perimeter arrives, this page picks it up on its own and keeps the same address.
Fire radiative power detected each day, in megawatts, and number of hotspots. The magenta bar marks the peak day.
It had gone 0 days without rain (1 mm or more) when it started. Rain came after the fire: 1.2 mm on 14 Oct.
Area with fire inside each municipality, rebuilt from heat detections (about 14 hectares per VIIRS pixel). An estimate until the official perimeter arrives. The distance runs from the point marking the centre of each area to the nearest fire: staying a kilometre away does not mean it reached the houses.
ECMWF ERA5 reanalysis at the fire location, the standard reference for past weather, and the Canadian Fire Weather Index (the same system Copernicus uses), computed by WorldFires from that data. Days after the fire run until the first rain.

It started with an FWI of 22.4, a minimum humidity of 46% and rain the day before. Fires in the area that started in weather like this since 2016: 25.
First rain (1 mm or more) after it ended: 1.1 mm on 17 Sept.
First rain (1 mm or more) after it ended: 1.1 mm on 8 Jul.
First rain (1 mm or more) after it ended: 5.2 mm on 13 Oct.
First rain (1 mm or more) after it ended: 2.8 mm on 4 Jul.
First rain (1 mm or more) after it ended: none in the following ten days.
It burned an area similar to its twins (238 ha against a median of 196 ha) and lasted 13 days, against 2 days.
In 2 of 25, not even 1 mm fell in the ten days after the end: they went out without rain. In the rest, the first rainy day brought a median of 2.1 mm.
This is a bank of analogues: it shows what usually happens, not what will happen. With fewer than 15 twins we give no figures. How we calculate it
It was considered over on 13 Oct, and on 14 Oct 1.2 mm fell. We do not know whether the rain or the firefighters put it out. Twins with rain when they ended: 23 of 25, with a median of 2.1 mm.

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.
On 11 October 2026 the air beside the fire reached 44 µg/m³ of PM2.5. That day averaged 23: 1.5 times the WHO daily guideline (15).

RSS Changes to this page With cross-checks and a citable version
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.
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.
