Berrahal fire, October 2025 برحال · Berrahal

Out · last detection 10 Oct 2025, 13:05 UTC

The fire started on 6 October 2025 in Berrahal, Algeria, and satellites saw it burning for 5 days. Copernicus mapped a burnt perimeter of 2,490 hectares from satellite imagery, spread across a single municipality.

It is the 9th largest in Annaba since 2016 (of 50 with a page). The largest in Algeria in 2025, of 35.

It had gone one day without rain (1 mm or more) when it started. Rain came after the fire: 8.6 mm on 15 Oct.

This area had burned before

94% of the perimeter overlaps earlier fires recorded since 2016: 389 ha in 2017, 2,143 ha in 2020, 1,039 ha in 2022. Part of it burned more than once, so the yearly figures add up to more than the 2,343 ha that had burned before.

How big is it?

It burned the equivalent of 1.6% of the area of London (25 km² against 1,583 km²).

Frequently asked questions

How long did the Berrahal fire last?
Copernicus dates it between 6 October 2025 and 10 October 2025: 5 days between the first and last image with fire.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 2,490 hectares (24.9 km²). Official national figures may differ.
Which municipalities burned?
The fire only entered Berrahal (2,494 ha, 14 %).
Did the fire reach a town?
The fire started in Berrahal and came within 35.8 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 31.4 °C, humidity dropped to 26 % and gusts hit 48 km/h. The fire danger index (FWI) reached 39, 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.

How we know this
  • Perimeter: EFFIS (Copernicus), mapped on satellite imagery.
  • Dates from the perimeter: the VIIRS detections inside it did not change them. 37 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.
