Sulina fire, 14 February 2025 Sulina
Out · last detection 18 Feb 2025, 23:27 UTC
The fire started on 14 February 2025 in Sulina, Romania, and satellites saw it burning for 5 days. Copernicus mapped a burnt perimeter of 1,244 hectares from satellite imagery, spread across a single municipality.
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.
The power measured by the satellite is low (1.3 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Inside the perimeter there was no noticeable built-up land and almost nobody lived there (GHSL 2025, 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 GHSL 2025 epoch is a projection made from 2020 and earlier data.

How a twin is chosen
- Same area: fires that have already ended, less than 250 km from this one, since 2019.
- Same start: we compare the FWI on the first day, the minimum humidity that day and the run of days without rain before it. The slider sets how much they may differ.
- Only pages with final weather data (ERA5 reanalysis) calculated in the same way as this fire’s; agricultural and grass burns and pages with data under review are left out.
- Fires burning at the same time as this one (a week before or after) are left out: they share the same spell of weather and do not count as a precedent.
- They are sorted by similarity, and the outlines of the first five are drawn.

Frequently asked questions
- How long did the Sulina fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 14 February 2025 to 18 February 2025 (5 days). The perimeter dates it from 14 February 2025 to 17 February 2025.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 1,244 hectares (12.4 km²). Official national figures may differ.
- Which municipalities burned?
- The fire only entered Sulina (1,245 ha, 3.8 %).
- Did the fire reach a town?
- The fire started in Sulina and came within 3.7 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 8.4 °C, humidity dropped to 50 % and gusts hit 46 km/h. The fire danger index (FWI) reached 4, class Very low.
- 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.
Report an error
How we know this
- Perimeter: EFFIS (Copernicus), mapped on satellite imagery.
- Dates adjusted with the VIIRS detections inside the perimeter, which said 14 February 2025 to 17 February 2025. One Suomi-NPP VIIRS detection 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 2025, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.
- 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.
