Out · last measured on 22 Jul 2017
The fire started on 19 July 2017 in El Kennar Nouchfi, Algeria, and satellites saw it burning for 4 days. Copernicus mapped a burnt perimeter of 486 hectares from satellite imagery, spread across 5 municipalities.
It is the 18th largest in Jijel since 2016 (of 110 with a page). Number 37 in Algeria in 2017, of 173.

We have the Copernicus perimeter for this fire, but the VIIRS sensors did not capture it in enough detail: no day-by-day evolution, but the split by municipality is there.

Inside 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.

It was 2.1 times larger than the median of its twins and lasted 4 days, against 3 days.
Only 9 of its 49 twins burned more. The weather on the first day does not explain everything: the wind in the following days, the fuel and the firefighting also count. In 13 of 49, not even 1 mm fell in the ten days after the end: they went out without rain. In the rest, the first rainy day brought a median of 2.1 mm.
This is a bank of analogues: it shows what usually happens, not what will happen. With fewer than 15 twins we give no figures. How we calculate it

How a twin is chosen
- Same area: fires that have already ended, less than 250 km from this one, since 2016.
- Same start: we compare the FWI on the first day, the minimum humidity that day and the run of days without rain before it. The slider sets how much they may differ.
- Only pages with final weather data (ERA5 reanalysis) calculated in the same way as this fire’s; agricultural and grass burns and pages with data under review are left out.
- Fires burning at the same time as this one (a week before or after) are left out: they share the same spell of weather and do not count as a precedent.
- They are sorted by similarity, and the outlines of the first five are drawn.

Frequently asked questions
- How long did the El Kennar Nouchfi fire last?
- Copernicus dates it between 19 July 2017 and 22 July 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 486 hectares (4.9 km²). Official national figures may differ.
- Which municipalities burned?
- The fire entered 5 municipalities: El Kennar Nouchfi (200 ha, 6.0 %); Djemaa Beni Habibi (166 ha, 3.8 %); Sidi Abdelaziz (117 ha, 2.7 %); Chekfa (4 ha, 0.1 %); Bordj Tahar (0 ha, 0.0 %).
- Did the fire reach a town?
- The fire came within 4.1 km of the centre of Djemaa Beni Habibi, the closest of the areas it touched. 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 32.4 °C, humidity dropped to 37 % and gusts hit 44 km/h. The fire danger index (FWI) reached 31, 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.
- How did the fires that started in similar weather in this area end?
- Fires less than 250 km away that started since 2016 with a similar FWI, humidity and dry spell: 49. Their median duration was 3 days and their median area 236 ha; 6 % went past 1,000 ha. Only 9 of its 49 twins burned more. The weather on the first day does not explain everything: the wind in the following days, the fuel and the firefighting also count. In 13 of 49, not even 1 mm fell in the ten days after the end: they went out without rain. In the rest, the first rainy day brought a median of 2.1 mm.

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.
Report an error
How we know this
- Perimeter: EFFIS (Copernicus), mapped on satellite imagery.
- Dates from the perimeter: the VIIRS detections inside it did not change them. No 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.
