Frequently asked questions

How long did the Zerdaza fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 27 August 2026 to 28 August 2026 (2 days). The perimeter dates it from 27 August 2026 to 27 August 2026.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 120 hectares (1.2 km²). Official national figures may differ.
Which municipalities burned?
The fire only entered Zerdaza (120 ha, 1.2 %).
Did the fire reach a town?
The closest fire to a town centre came within 3.1 km of Zerdaza. 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 46.5 °C, humidity dropped to 7 % and gusts hit 56 km/h. The fire danger index (FWI) reached 88, class Very 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.

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.
