Bakhmut fire, 5 July 2026 Бахмутський район · Bakhmut, Perevalsk

Out · last detection 5 Jul 2026, 11:10 UTC

The fire started on 5 July 2026 in Bakhmut, Ukraine, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 397 hectares from satellite imagery, spread across 2 municipalities.

It is the 162th largest in Donetsk Oblast since 2016 (of 1004 with a page). Number 199 in Ukraine in 2026, of 984.

The power measured by the satellite is low (23.0 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Fire radiative power detected each day, in megawatts, and number of hotspots. The magenta bar marks the peak day.

This area had burned before

93% of the perimeter overlaps earlier fires recorded since 2016: 85 ha in 2023, 368 ha in 2024, 126 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 368 ha that had burned before.

Frequently asked questions

How long did the Bakhmut fire last?
Copernicus dates it between 5 July 2026 and 5 July 2026: 1 day between the first and last image with fire.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 397 hectares (4.0 km²). Official national figures may differ.
Which municipalities burned?
The fire entered 2 municipalities: Bakhmut (393 ha, 0.2 %); Perevalsk (2 ha, 0.0 %).
Did the fire reach a town?
The closest fire to a town centre came within 26.4 km of Perevalsk. That is the distance to the perimeter or nearest hotspot; it does not mean it entered the houses.
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.

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.

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.
