Frequently asked questions

How long did the Fermoselle fire last?
Copernicus dates it between 29 July 2026 and 29 July 2026: 1 day between the first and last image with fire.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 11,099 hectares (111.0 km²). Official national figures may differ.
Which municipalities burned?
The fire entered 6 municipalities: Villar del Buey (4,103 ha, 30 %); Fariza (2,951 ha, 33 %); Fermoselle (2,414 ha, 35 %); Muga de Sayago (1,637 ha, 45 %); Villarino de los Aires (3 ha, 0.0 %); Trabanca (1 ha, 0.0 %).
Did the fire reach a town?
The closest fire to a town centre came within 0.5 km of Fermoselle. 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 37.2 °C, humidity dropped to 15 % and gusts hit 45 km/h. The fire danger index (FWI) reached 57, class Extreme.
Where does this data come from?
From the EFFIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Spain (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.

Emergency number: 112

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.

We will only use your email to reply about this report. Privacy. This is not an emergency service: if there is a fire now, call 112.

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 4.0 International (CC BY 4.0)). 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.
