Ben Allel fire, June 2019 بن علال، عين الدفلى · Ben Allel, Miliana
The fire started on 25 June 2019 in Ben Allel, Algeria, and satellites saw it burning for 3 days. Copernicus mapped a burnt perimeter of 645 hectares from satellite imagery, spread across 2 municipalities.
It is the 12th largest in Tipaza since 2016 (of 59 with a page). Number 17 in Algeria in 2019, of 78.
The power measured by the satellite is low (24.0 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

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 29 days without rain (1 mm or more) when it started. Rain came after the fire: 1.4 mm on 5 Jul.
This area had burned before
40% of the perimeter overlaps earlier fires recorded since 2016: 256 ha in 2016.

2 ha reached on 26 Jun0.0 %
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.

The smoke
CAMS · CopernicusOn 24 June 2019 the air beside the fire reached 44 µg/m³ of PM2.5. That day averaged 31: 2.1 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Ben Allel fire last?
- Copernicus dates it between 25 June 2019 and 27 June 2019: 3 days between the first and last image with fire.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 645 hectares (6.4 km²). Official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Ben Allel (645 ha, 4.5 %); Miliana (2 ha, 0.0 %).
- Did the fire reach a town?
- The closest fire to a town centre came within 1.4 km of Ben Allel. That is the distance to the perimeter or nearest hotspot; it does not mean it entered the houses.
- What was the weather like?
- During the fire the temperature reached 32.0 °C, humidity dropped to 13 % and gusts hit 38 km/h. The fire danger index (FWI) reached 42, class Very 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.

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.
