Zighoud Youcef fire, August 2016 زيغود يوسف · Zighoud Youcef, Ibn Badis
The fire started on 22 August 2016 in Zighoud Youcef, Algeria, and satellites saw it burning for 10 days. Copernicus mapped a burnt perimeter of 541 hectares from satellite imagery, spread across 2 municipalities.
It is the 29th largest in Skikda since 2016 (of 102 with a page). Number 16 in Algeria in 2016, of 62.
The power measured by the satellite is low (27.9 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.
What burned
- Mixed forest70 %

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 smoke
CAMS · CopernicusOn 20 August 2016 the air beside the fire reached 47 µg/m³ of PM2.5. That day averaged 29: 1.9 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Zighoud Youcef fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 22 August 2016 to 31 August 2016 (10 days). The perimeter dates it from 22 August 2016 to 25 August 2016.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 541 hectares (5.4 km²). Official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Zighoud Youcef (440 ha, 1.8 %); Ibn Badis (102 ha, 0.3 %).
- Did the fire reach a town?
- The fire started in Zighoud Youcef and came within 10.1 km of its centre. That is the distance from the perimeter, or the nearest hotspot, to the point marking the centre; it does not mean it entered the houses.
- What was the weather like?
- During the fire the temperature reached 28.9 °C, humidity dropped to 32 % and gusts hit 38 km/h. The fire danger index (FWI) reached 32, class High.
- Where does this data come from?
- From the EFFIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Algeria (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 adjusted with the VIIRS detections inside the perimeter, which said 22 August 2016 to 25 August 2016. 38 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 ADM3 (Creative Commons Attribution-ShareAlike 2.0). 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.
