Kadiria fire, July 2026 Kadiria, Maala, Lakhdaria
The fire started on 16 July 2026 in Kadiria, Algeria, and satellites saw it burning for 4 days. Copernicus mapped a burnt perimeter of 2,087 hectares from satellite imagery, spread across 3 municipalities.
It is the 4th largest in Blida since 2016 (of 38 with a page). Number 36 in Algeria in 2026, of 197.
The power measured by the satellite is low (20.0 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

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.

People and buildings inside the perimeter
GHSL 2025Inside the perimeter there were about 9.9 hectares of built-up land and about 1,600 residents (GHSL 2025, 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. The GHSL 2025 epoch is a projection made from 2020 and earlier data.

The smoke
CAMS · CopernicusOn 18 July 2026 the air beside the fire reached 25 µg/m³ of PM2.5. That day averaged 17: 1.2 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Kadiria fire last?
- The official perimeter only gives the start date (16 July 2026). The end comes from the heat detections inside the perimeter: it burned until 19 July 2026 (4 days from 16 July 2026), the last day with detections before more than 10 days in a row without any, so it is approximate.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 2,087 hectares (20.9 km²). Official national figures may differ.
- Which municipalities burned?
- The fire entered 3 municipalities: Kadiria (1,517 ha, 16 %); Maala (544 ha, 9.8 %); Lakhdaria (30 ha, 0.3 %).
- Did the fire reach a town?
- The fire came within 3.7 km of the centre of Lakhdaria, 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 44.2 °C, humidity dropped to 5 % and gusts hit 32 km/h. The fire danger index (FWI) reached 68, 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.
- The official perimeter has no end date: the end is the last day with VIIRS detections inside the perimeter before a gap of more than 10 days (150 days at most), so it is approximate. 18 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 2025, 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.
