Asfour fire, July 2016 عصفور · Asfour, Chihani
The fire started on 22 July 2016 in Asfour, Algeria, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 155 hectares from satellite imagery, spread across 2 municipalities.
It is the 93th largest in El Tarf since 2016 (of 121 with a page). Number 47 in Algeria in 2016, of 62.

Burnt area inside each municipality, from crossing the official perimeter with administrative boundaries. The distance is from the town centre 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.

The smoke
CAMS · CopernicusOn 31 July 2016 the air beside the fire reached 80 µg/m³ of PM2.5. That day averaged 41: 2.7 times the WHO daily guideline (15).
Particles from the Copernicus CAMS model at the centre of the perimeter; these are not measurements in each town. The pale bar is the worst hour, the solid one the daily average.

Frequently asked questions
- How long did the Asfour fire last?
- Copernicus dates it between 22 July 2016 and 22 July 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 155 hectares (1.6 km²). Official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Asfour (123 ha, 1.2 %); Chihani (32 ha, 0.2 %).
- Did the fire reach a town?
- The closest fire to a town centre came within 3.6 km of Asfour. 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 36.6 °C, humidity dropped to 24 % and gusts hit 32 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.

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.
