Kadiria fire, July 2020 Kadiria, Chaabet El Ameur, Lakhdaria

Out · last detection 23 Jul 2020, 11:40 UTC

The fire started on 21 July 2020 in Kadiria, Algeria, and satellites saw it burning for 3 days. Copernicus mapped a burnt perimeter of 473 hectares from satellite imagery, spread across 3 municipalities.

It is the 16th largest in Blida since 2016 (of 38 with a page). Number 55 in Algeria in 2020, of 236.

The power measured by the satellite is low (24.5 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Frequently asked questions

How long did the Kadiria fire last?
Copernicus dates it between 21 July 2020 and 23 July 2020: 3 days between the first and last image with fire.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 473 hectares (4.7 km²). Official national figures may differ.
Which municipalities burned?
The fire entered 3 municipalities: Kadiria (436 ha, 4.7 %); Chaabet El Ameur (34 ha, 0.4 %); Lakhdaria (4 ha, 0.0 %).
Did the fire reach a town?
The fire came within 4.4 km of the centre of Chaabet El Ameur, 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 38.2 °C, humidity dropped to 22 % and gusts hit 42 km/h. The fire danger index (FWI) reached 48, 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.

How we know this
  • Perimeter: EFFIS (Copernicus), mapped on satellite imagery.
  • Dates from the perimeter: the VIIRS detections inside it did not change them. 17 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.

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.
