Sulina fire, 9 April 2022 Sulina, Crișan
The fire started on 9 April 2022 in Sulina, Romania, and satellites saw it burning for 2 days. Copernicus mapped a burnt perimeter of 967 hectares from satellite imagery, spread across 2 municipalities.
This record is fire in the reed beds of the Danube Delta, not a forest fire. Thousands of hectares of reed burn in the delta every year, mostly between January and April, and many of these burns are deliberate. That is why it is left out of the fire rankings.

Burnt area inside each municipality, from crossing the official perimeter with administrative boundaries. The distance runs from the point marking the centre of each area to the nearest fire: staying a kilometre away does not mean it reached the houses.

The smoke
CAMS · CopernicusOn 8 April 2022 the air beside the fire reached 16 µg/m³ of PM2.5, but no daily average passed the WHO guideline (15).
Particles from the Copernicus CAMS model at the centre of the perimeter; these are not measurements in each town. The pale bar is the worst hour, the solid one the daily average.

Frequently asked questions
- How long did the Sulina fire last?
- Copernicus dates it between 9 April 2022 and 10 April 2022: 2 days between the first and last image with fire.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 967 hectares (9.7 km²). Official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Sulina (945 ha, 2.9 %); Crișan (21 ha, 0.0 %).
- Did the fire reach a town?
- The fire came within 11.4 km of the centre of Crișan, the closest of the areas it touched. 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 21.5 °C, humidity dropped to 48 % and gusts hit 54 km/h. The fire danger index (FWI) reached 12, 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 from the perimeter: the VIIRS detections inside it did not change them. 15 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.
- Probably a vegetation burn: not counted in the totals.
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.
