Es Sebt fire, August 2019 السبت · Es Sebt, Roknia
The fire started on 6 August 2019 in Es Sebt, Algeria, and satellites saw it burning for 6 days. Copernicus mapped a burnt perimeter of 1,027 hectares from satellite imagery, spread across 2 municipalities.

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 more than two months without rain (1 mm or more) when it started. Rain came after the fire: 1.3 mm on 13 Aug.
This area had burned before
13% of the perimeter overlaps earlier fires recorded since 2016: 129 ha in 2017.

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.

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.

The smoke
CAMS · CopernicusOn 7 August 2019 the air beside the fire reached 45 µg/m³ of PM2.5. That day averaged 32: 2.1 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Es Sebt fire last?
- Copernicus dates it between 6 August 2019 and 11 August 2019: 6 days between the first and last image with fire.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 1,027 hectares (10.3 km²). Official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Es Sebt (934 ha, 3.8 %); Roknia (95 ha, 0.5 %).
- Did the fire reach a town?
- The fire started in Es Sebt and came within 6.2 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 43.0 °C, humidity dropped to 10 % and gusts hit 50 km/h. The fire danger index (FWI) reached 65, class Extreme.
- 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 from the perimeter: the VIIRS detections inside it did not change them. 70 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 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.
