Gouraya fire, October 2020 قوراية · Gouraya

Out · last detection 21 Oct 2020, 02:12 UTC

The fire started on 20 October 2020 in Gouraya, Algeria, and satellites saw it burning for 2 days. Copernicus mapped a burnt perimeter of 359 hectares from satellite imagery, spread across a single municipality.

It is the 18th largest in Tipaza since 2016 (of 59 with a page). Number 87 in Algeria in 2020, of 236.

The power measured by the satellite is low (5.5 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 Gouraya fire last?
Copernicus dates it between 20 October 2020 and 21 October 2020: 2 days between the first and last image with fire.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 359 hectares (3.6 km²). Official national figures may differ.
Which municipalities burned?
The fire only entered Gouraya (360 ha, 4.1 %).
Did the fire reach a town?
The fire started in Gouraya and came within 2.8 km of its centre. 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 27.8 °C, humidity dropped to 25 % and gusts hit 46 km/h. The fire danger index (FWI) reached 27, 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.

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. 2 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.
