Zemmouri fire, October 2016 زموري · Thenia, Zemmouri, Tidjelabine
The fire started on 24 October 2016 in Zemmouri, Algeria, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 744 hectares from satellite imagery, spread across 4 municipalities.
It is the 2th largest in Boumerdes since 2016 (of 11 with a page). Number 8 in Algeria in 2016, of 62.

Where it burned
How it evolved, day by day
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 2 days without rain (1 mm or more) when it started. Rain came after the fire: 1.4 mm on 28 Oct.

The smoke
CAMS · CopernicusOn 25 October 2016 the air beside the fire reached 113 µg/m³ of PM2.5. That day averaged 43: 2.9 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Zemmouri fire last?
- Copernicus dates it between 24 October 2016 and 24 October 2016: 1 day between the first and last image with fire.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 744 hectares (7.4 km²). Official national figures may differ.
- Which municipalities burned?
- The fire entered 4 municipalities: Thenia (593 ha, 14 %); Zemmouri (132 ha, 2.4 %); Tidjelabine (13 ha, 0.3 %); Boumerdès (8 ha, 0.4 %).
- Did the fire reach a town?
- The closest fire to a town centre came within 2.0 km of Thenia. 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 33.3 °C, humidity dropped to 23 % and gusts hit 43 km/h. The fire danger index (FWI) reached 22, 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.

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.
