The fire started on 7 February 2020 in Vega de Pas, Spain, and satellites saw it burning for 2 days. Copernicus mapped a burnt perimeter of 172 hectares from satellite imagery, spread across a single municipality. According to EGIF (MITECO), the largest of the 5 recorded fires was detected on 2 February 2020 at 21:45 and declared extinguished on 3 February 2020.
It is the 91th largest in Cantabria since 2016 (of 179 with a page). Number 56 in Spain in 2020, of 89.
The power measured by the satellite is low (2.0 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

This area had burned before
68% of the perimeter overlaps earlier fires recorded since 2016: 43 ha in 2018, 111 ha in 2019. Part of it burned more than once, so the yearly figures add up to more than the 117 ha that had burned before.

Burnt area inside each municipality, from crossing the official perimeter with administrative boundaries. The distance runs from the point marking the centre of each area to the nearest fire: staying a kilometre away does not mean it reached the houses.

Official record
Complex of 5 fires according to EGIF (MITECO)
According to EGIF (MITECO), 5 fires started inside this perimeter on these dates, totalling 165 ha (the satellite measured 172 ha).
EGIF (MITECO) records each fire that started at a different time or place separately; the satellite sees a single burned area, so this page groups them together. The numbers on the map show where each one started.
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.

How a twin is chosen
Same area: fires that have already ended, less than 250 km from this one, since 2016.
Same start: we compare the FWI on the first day, the minimum humidity that day and the run of days without rain before it. The slider sets how much they may differ.
Only pages with final weather data (ERA5 reanalysis) calculated in the same way as this fire’s; agricultural and grass burns and pages with data under review are left out.
Fires burning at the same time as this one (a week before or after) are left out: they share the same spell of weather and do not count as a precedent.
They are sorted by similarity, and the outlines of the first five are drawn.

Copernicus dates it between 7 February 2020 and 8 February 2020: 2 days between the first and last image with fire. According to EGIF (MITECO), the largest of the 5 recorded fires was detected on 2 February 2020 at 21:45 and declared extinguished on 3 February 2020.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 172 hectares (1.7 km²). Official national figures may differ.
Which municipalities burned?
The fire only entered Vega de Pas (172 ha, 2.0 %).
Did the fire reach a town?
The fire started in Vega de Pas and came within 4.3 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 13.8 °C, humidity dropped to 50 % and gusts hit 31 km/h. The fire danger index (FWI) reached 1, class Very low.
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.
How did the fires that started in similar weather in this area end?
Fires less than 250 km away that started since 2016 with a similar FWI, humidity and dry spell: 42. Their median duration was 2 days and their median area 198 ha; 0 % went past 1,000 ha. All of them had rain in the ten days after the end: the first rainy day brought a median of 6.9 mm.
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.
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.

Perimeter: EFFIS (Copernicus), mapped on satellite imagery.
Dates from the perimeter: the VIIRS detections inside it did not change them. One Suomi-NPP VIIRS detection on those dates.
Compared with EGIF (MITECO): 165 official ha against 172 ha of perimeter; they agree within 25%.
Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.
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.
