حاسي الفريد fire, September 2017 حاسي الفريد, القصرين الجنوبية
The fire started on 14 September 2017 in حاسي الفريد, Tunisia, and satellites saw it burning for 4 days. Copernicus mapped a burnt perimeter of 311 hectares from satellite imagery, spread across 2 municipalities.
It is the 22th largest in Kasserine since 2016 (of 32 with a page). Number 16 in Tunisia in 2017, of 31.
The power measured by the satellite is low (20.8 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

The weather it burned in
It had gone 6 days without rain (1 mm or more) when it started. Rain came after the fire: 2.9 mm on 27 Sept.
This area had burned before
No earlier perimeters overlap this fire since 2016, when the satellite record begins.

27 ha reached on 15 Sept0.0 %
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.
What burned
- Coniferous forest72 %
- Agricultural areas18 %
- Scrub and transitional woodland8.4 %
- Other land cover1.3 %
Land cover inside the perimeter as reported by Copernicus EFFIS (outside the Corine Land Cover area).
People and buildings inside the perimeter
GHSL 2015Inside the perimeter there was no noticeable built-up land and almost nobody lived there (GHSL 2015, 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 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 حاسي الفريد fire last?
- Copernicus dates it between 14 September 2017 and 17 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 311 hectares (3.1 km²). Official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: حاسي الفريد (285 ha, 0.3 %); القصرين الجنوبية (27 ha, 0.0 %).
- What was the weather like?
- During the fire the temperature reached 32.7 °C, humidity dropped to 9 % and gusts hit 46 km/h. The fire danger index (FWI) reached 54, class 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.

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.

How we know this
- Perimeter: EFFIS (Copernicus), mapped on satellite imagery.
- Dates from the perimeter: the VIIRS detections inside it did not change them. 31 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.
- Built-up area and population come from the JRC Global Human Settlement Layer (epoch 2015, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.
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.
