Prunișor fire, 23 March 2022 Prunișor
The fire started on 23 March 2022 in Prunișor, Romania, and satellites saw it burning for 6 days. Copernicus mapped a burnt perimeter of 592 hectares from satellite imagery, spread across a single municipality.
It is the 6th largest in Mehedinți since 2016 (of 87 with a page). Number 14 in Romania in 2022, of 186.

People and buildings inside the perimeter
GHSL 2020Inside 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.

The smoke
CAMS · CopernicusOn 29 March 2022 the air beside the fire reached 31 µg/m³ of PM2.5. That day averaged 23: 1.6 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Prunișor fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 23 March 2022 to 28 March 2022 (6 days). The perimeter dates it from 23 March 2022 to 26 March 2022.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 592 hectares (5.9 km²). Official national figures may differ.
- Which municipalities burned?
- The fire only entered Prunișor (591 ha, 4.8 %).
- What was the weather like?
- During the fire the temperature reached 20.6 °C, humidity dropped to 15 % and gusts hit 45 km/h. The fire danger index (FWI) reached 16, class Moderate.
- Where does this data come from?
- From the EFFIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Romania (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 23 March 2022 to 26 March 2022. 27 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.
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 (Creative Commons Attribution 4.0 International (CC BY 4.0)). 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.
