فريانة fire, July 2021 فريانة
The fire started on 1 July 2021 in فريانة, Tunisia, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 145 hectares from satellite imagery, spread across a single municipality.
It is the 26th largest in Kasserine since 2016 (of 32 with a page). Number 30 in Tunisia in 2021, of 37.
The power measured by the satellite is low (18.5 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 27 days without rain (1 mm or more) when it started. Rain came after the fire: 1.1 mm on 10 Jul.
This area had burned before
No earlier perimeters overlap this fire since 2016, when the satellite record begins.

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 weather day by day
ECMWF ERA5 reanalysis at the fire location, the standard reference for past weather, and the Canadian Fire Weather Index (the same system Copernicus uses), computed by WorldFires from that data. Days after the fire run until the first rain.

Frequently asked questions
- How long did the فريانة fire last?
- Copernicus dates it between 1 July 2021 and 1 July 2021: 1 day between the first and last image with fire.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 145 hectares (1.4 km²). Official national figures may differ.
- Which municipalities burned?
- The fire only entered فريانة (146 ha, 0.1 %).
- What was the weather like?
- During the fire the temperature reached 38.2 °C, humidity dropped to 7 % and gusts hit 62 km/h. The fire danger index (FWI) reached 82, class Very extreme.
- Where does this data come from?
- From the EFFIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Tunisia (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: 198

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 (Open Data Commons Open Database License 1.0). 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.
