How long did the Zmiiv fire last?

Copernicus dates it between 29 March 2024 and 29 March 2024: 1 day between the first and last image with fire.

How much area did it burn?

The perimeter Copernicus measured from satellite imagery is 108 hectares (1.1 km²). Official national figures may differ.

Which municipalities burned?

The fire only entered Zmiiv (108 ha, 0.1 %).

Did the fire reach a town?

The fire started in Zmiiv and came within 17.5 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 18.7 °C, humidity dropped to 40 % and gusts hit 37 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 29 Mar 2024

The fire started on 29 March 2024 in Zmiiv, Ukraine, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 108 hectares from satellite imagery, spread across a single municipality.

It is the 495th largest in Kharkiv Oblast since 2016 (of 558 with a page). Number 1904 in Ukraine in 2024, of 2092.

We have the Copernicus perimeter for this fire, but the VIIRS sensors did not capture it in enough detail: no day-by-day evolution, but the split by municipality is there.

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.
