Simferopol fire, July 2025 Сімферопольський район · Simferopol

Out · last detection 19 Jul 2025, 10:40 UTC

The fire started on 19 July 2025 in Simferopol, Ukraine, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 121 hectares from satellite imagery, spread across a single municipality.

It is the 89th largest in Autonomous Republic of Crimea since 2016 (of 100 with a page). Number 1109 in Ukraine in 2025, of 1359.

The power measured by the satellite is low (10.9 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Frequently asked questions

How long did the Simferopol fire last?
Copernicus dates it between 19 July 2025 and 19 July 2025: 1 day between the first and last image with fire.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 121 hectares (1.2 km²). Official national figures may differ.
Which municipalities burned?
The fire only entered Simferopol (121 ha, 0.1 %).
Did the fire reach a town?
The closest fire to a town centre came within 30.1 km of Simferopol. That is the distance to the perimeter or nearest hotspot; it does not mean it entered the houses.
What was the weather like?
During the fire the temperature reached 28.9 °C, humidity dropped to 45 % and gusts hit 37 km/h. The fire danger index (FWI) reached 25, 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.

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.
