Zarichne fire, 15 March 2022 Зарічненський район · Zarichne

Out · last detection 17 Mar 2022, 11:56 UTC

The fire started on 15 March 2022 in Zarichne, Ukraine, and satellites saw it burning for 5 days. Copernicus mapped a burnt perimeter of 288 hectares from satellite imagery, spread across a single municipality.

It is the 73th largest in Rivne Oblast since 2016 (of 167 with a page). Number 174 in Ukraine in 2022, of 531.

The power measured by the satellite is low (12.1 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Built-up area< 0.1 ha
Residents< 20

Inside the perimeter there was no noticeable built-up land and almost nobody lived there (GHSL 2020, satellite-based estimate).

This is an estimate on 100 m cells, made from satellite imagery and census data: it does not mean that homes burned or that anyone was harmed. The perimeter also contains land that never burned.

Frequently asked questions

How long did the Zarichne fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 15 March 2022 to 19 March 2022 (5 days). The perimeter dates it from 17 March 2022 to 17 March 2022.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 288 hectares (2.9 km²). Official national figures may differ.
Which municipalities burned?
The fire only entered Zarichne (288 ha, 0.2 %).
Did the fire reach a town?
The fire started in Zarichne and came within 34.6 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 5.0 °C, humidity dropped to 32 % and gusts hit 28 km/h. The fire danger index (FWI) reached 3, 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.

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.

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 adjusted with the VIIRS detections inside the perimeter, which said 17 March 2022 to 17 March 2022. 4 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.
  • Built-up area and population come from the JRC Global Human Settlement Layer (epoch 2020, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.

How we build fire pages: methodology ›

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.
