Bouzguen fire, August 2025 بوزقن · Bouzguen, Idjer
The fire started on 19 August 2025 in Bouzguen, Algeria, and satellites saw it burning for 6 days. Copernicus mapped a burnt perimeter of 126 hectares from satellite imagery, spread across 2 municipalities.
It is the 36th largest in Tizi Ouzou since 2016 (of 46 with a page). Number 28 in Algeria in 2025, of 35.
The power measured by the satellite is low (17.2 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

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 24 days without rain (1 mm or more) when it started. Rain came after the fire: 1.0 mm on 24 Aug.
This area had burned before
77% of the perimeter overlaps earlier fires recorded since 2016: 87 ha in 2020, 1 ha in 2021, 11 ha in 2023.

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.

Land cover inside the perimeter as reported by Copernicus EFFIS (outside the Corine Land Cover area).
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.

Frequently asked questions
- How long did the Bouzguen fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 19 August 2025 to 24 August 2025 (6 days). The perimeter dates it from 19 August 2025 to 20 August 2025.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 126 hectares (1.3 km²). Official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Bouzguen (93 ha, 1.4 %); Idjer (33 ha, 0.4 %).
- Did the fire reach a town?
- The fire started in Bouzguen and came within 2.2 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 30.1 °C, humidity dropped to 27 % and gusts hit 49 km/h. The fire danger index (FWI) reached 30, 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 19 August 2025 to 20 August 2025. 14 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.
