CRISAN fire, 18 January 2025 CRISAN
The fire started on 18 January 2025 in CRISAN, Romania, and satellites saw it burning for 2 days. Copernicus mapped a burnt perimeter of 476 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 (6.7 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Where it burned
How it evolved, day by day
Fire radiative power detected each day, in megawatts, and number of hotspots. The magenta bar marks the peak day.
The weather it burned in
It had gone 13 days without rain (1 mm or more) when it started. Rain came after the fire: 7.4 mm on 25 Jan.
This area had burned before
96% of the perimeter overlaps earlier fires recorded since 2016: 150 ha in 2019, 181 ha in 2020, 412 ha in 2022. Part of it burned more than once, so the yearly figures add up to more than the 457 ha that had burned before.

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

The smoke
CAMS · CopernicusOn 16 January 2025 the air beside the fire reached 26 µg/m³ of PM2.5. That day averaged 21: 1.4 times the WHO daily guideline (15).

Frequently asked questions
- How long did the CRISAN fire last?
- Copernicus dates it between 18 January 2025 and 19 January 2025: 2 days between the first and last image with fire.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 476 hectares (4.8 km²). Official national figures may differ.
- Which municipalities burned?
- The fire only entered CRISAN (476 ha, 1.2 %).
- Did the fire reach a town?
- The closest fire to a town centre came within 8.7 km of CRISAN. That is the distance to the perimeter or nearest hotspot; it does not mean it entered the houses.
- What was the weather like?
- During the fire the temperature reached 8.0 °C, humidity dropped to 61 % and gusts hit 39 km/h. The fire danger index (FWI) reached 2, 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.
Emergency number: 112
Satellite cross-check
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.

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.
