Zekri fire, 12 August 2020 زكري · Zekri

Out · last measured on 15 Aug 2020

The fire started on 12 August 2020 in Zekri, Algeria, and satellites saw it burning for 4 days. Copernicus mapped a burnt perimeter of 427 hectares from satellite imagery, spread across a single municipality.

It is the 42th largest in Bejaia since 2016 (of 101 with a page). Number 66 in Algeria in 2020, of 236.

We have the Copernicus perimeter for this fire, but the VIIRS sensors did not capture it in enough detail: no day-by-day evolution, but the split by municipality is there.

Frequently asked questions

How long did the Zekri fire last?
Copernicus dates it between 12 August 2020 and 15 August 2020: 4 days between the first and last image with fire.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 427 hectares (4.3 km²). Official national figures may differ.
Which municipalities burned?
The fire only entered Zekri (246 ha, 2.8 %).
Did the fire reach a town?
The closest fire to a town centre came within 3.8 km of Zekri. 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 31.3 °C, humidity dropped to 28 % and gusts hit 40 km/h. The fire danger index (FWI) reached 38, 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.

Satellite cross-check

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.
