How long did the CRISAN fire last?

Copernicus dates it between 25 September 2017 and 28 September 2017: 4 days between the first and last image with fire.

How much area did it burn?

The perimeter Copernicus measured from satellite imagery is 454 hectares (4.5 km²). Official national figures may differ.

Which municipalities burned?

The fire only entered CRISAN (455 ha, 1.2 %).

Did the fire reach a town?

The closest fire to a town centre came within 9.5 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 23.2 °C, humidity dropped to 45 % and gusts hit 62 km/h. The fire danger index (FWI) reached 37, class High.

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.

CRISAN fire, 25 September 2017 CRISAN

Out · last detection 28 Sept 2017, 00:10 UTC

The fire started on 25 September 2017 in CRISAN, Romania, and satellites saw it burning for 4 days. Copernicus mapped a burnt perimeter of 454 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 (23.4 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

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.
