Jiana fire, 4 August 2021 Jiana, Devesel, Gogoșu

Out · last detection 7 Aug 2021, 11:17 UTC

The fire started on 4 August 2021 in Jiana, Romania, and satellites saw it burning for 6 days. Copernicus mapped a burnt perimeter of 1,250 hectares from satellite imagery, spread across 3 municipalities.

It is the 3th largest in Mehedinți since 2016 (of 87 with a page). Number 2 in Romania in 2021, of 23.

The power measured by the satellite is low (20.9 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

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.

Copernicus dates it between 4 August 2021 and 9 August 2021: 6 days between the first and last image with fire.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 1,250 hectares (12.5 km²). Official national figures may differ.
Which municipalities burned?
The fire entered 3 municipalities: Jiana (689 ha, 6.8 %); Devesel (398 ha, 3.8 %); Gogoșu (164 ha, 1.4 %).
What was the weather like?
During the fire the temperature reached 35.9 °C, humidity dropped to 25 % and gusts hit 55 km/h. The fire danger index (FWI) reached 39, class Very 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.

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.

We will only use your email to reply about this report. Privacy. This is not an emergency service: if there is a fire now, call 112.

How we know this
  • Perimeter: EFFIS (Copernicus), mapped on satellite imagery.
  • Dates from the perimeter: the VIIRS detections inside it did not change them. 17 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.

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.
