How long did the Landiras fire last?

According to the heat detections seen by satellite inside the perimeter, it burned from 7 July 2022 to 20 July 2022 (14 days). The perimeter dates it from 7 July 2022 to 19 July 2022.

How much area did it burn?

The perimeter Copernicus measured from satellite imagery is 13,116 hectares (131.2 km²). Official national figures may differ.

Which municipalities burned?

The fire entered 10 municipalities: Louchats (2,596 ha, 66 %); Landiras (1,994 ha, 33 %); Guillos (1,881 ha, 83 %); Origne (1,697 ha, 76 %); Hostens (1,390 ha, 24 %); Saint-Symphorien (1,364 ha, 13 %); Saint-Magne (789 ha, 9.5 %); Balizac (777 ha, 19 %); Cabanac-et-Villagrains (560 ha, 8.0 %); Le Tuzan (69 ha, 3.8 %).

Did the fire reach a town?

The fire reached the centre of Guillos: the point marking it was inside the burnt area or less than 500 metres from it. That does not mean houses burned.

What was the weather like?

During the fire the temperature reached 41.2 °C, humidity dropped to 13 % and gusts hit 48 km/h. The fire danger index (FWI) reached 45, class Very high.

Where does this data come from?

From the EFFIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of France (geoBoundaries). It is not an official report.

Official record

According to BDIFF, a fire of 12,552 ha was recorded in Landiras on 12 July 2022 (the satellite measured 13,116 ha). The record has no coordinates, so it was matched by municipality and date.

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 adjusted with the VIIRS detections inside the perimeter, which said 7 July 2022 to 19 July 2022. 1,891 Suomi-NPP VIIRS detections on those dates.
Compared with BDIFF: 12,552 official ha against 13,116 ha of perimeter; they agree within 25%.
Checked against news and agencies: 3 confirmed sources.
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 ADM5 (Open Data Commons Attribution License 1.0). 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.
