How long did the Rivne fire last?

Copernicus dates it between 23 February 2025 and 23 February 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 252 hectares (2.5 km²). Official national figures may differ.

Which municipalities burned?

The fire only entered Rivne (252 ha, 0.1 %).

Did the fire reach a town?

The fire started in Rivne and came within 15.7 km of its centre. That is the distance from the perimeter, or the nearest hotspot, to the point marking the centre; it does not mean it entered the houses.

What was the weather like?

During the fire the temperature reached 3.9 °C, humidity dropped to 34 % and gusts hit 32 km/h. The fire danger index (FWI) reached 1, class Very low.

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.

Out · last measured on 23 Feb 2025

The fire started on 23 February 2025 in Rivne, Ukraine, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 252 hectares from satellite imagery, spread across a single municipality.

It is the 87th largest in Rivne Oblast since 2016 (of 167 with a page). Number 490 in Ukraine in 2025, of 1359.

We have the Copernicus perimeter for this fire, but not yet its hotspots: NASA publishes the yearly hotspot archive only once the year closes. The page picks it up automatically when it is available.

It had gone 8 days without rain (1 mm or more) when it started. Rain came after the fire: 3.4 mm on 28 Feb.

This area had burned before

59% of the perimeter overlaps earlier fires recorded since 2016: 137 ha in 2022, 35 ha in 2024. Part of it burned more than once, so the yearly figures add up to more than the 148 ha that had burned before.

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.
Dates from the perimeter: the VIIRS detections inside it did not change them. No 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.
