Vega de Pas fire, February 2025 Vega de Pas, Selaya, San Roque de Riomiera

Out · last detection 19 Feb 2025, 14:14 UTC

The fire started on 19 February 2025 in Vega de Pas, Spain, and satellites saw it burning for 5 days. Copernicus mapped a burnt perimeter of 1,745 hectares from satellite imagery, spread across 3 municipalities.

It is the 3th largest in Cantabria since 2016 (of 179 with a page). Number 34 in Spain in 2025, of 158.

The power measured by the satellite is low (21.0 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

It had gone 5 days without rain (1 mm or more) when it started. Rain came after the fire: 2.0 mm on 24 Feb.

This area had burned before

94% of the perimeter overlaps earlier fires recorded since 2016: 77 ha in 2017, 174 ha in 2018, 904 ha in 2019, 617 ha in 2020, 997 ha in 2021, 1,068 ha in 2022, 756 ha in 2023, 559 ha in 2024. Part of it burned more than once, so the yearly figures add up to more than the 1,632 ha that had burned before.

How big is it?

It burned the equivalent of 1.1% of the area of London (17 km² against 1,583 km²).

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.

Built-up area0.15 ha
Residents< 20

Inside the perimeter there were about 0.15 hectares of built-up land and almost nobody lived there (GHSL 2025, satellite-based estimate).

This is an estimate on 100 m cells, made from satellite imagery and census data: it does not mean that homes burned or that anyone was harmed. The perimeter also contains land that never burned. The GHSL 2025 epoch is a projection made from 2020 and earlier data.

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.

Frequently asked questions

How long did the Vega de Pas fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 19 February 2025 to 23 February 2025 (5 days). The perimeter dates it from 19 February 2025 to 22 February 2025.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 1,745 hectares (17.4 km²). Official national figures may differ.
Which municipalities burned?
The fire entered 3 municipalities: Vega de Pas (784 ha, 9.0 %); Selaya (569 ha, 14 %); San Roque de Riomiera (392 ha, 11 %).
Did the fire reach a town?
The fire started in Vega de Pas and came within 2.7 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 14.8 °C, humidity dropped to 47 % and gusts hit 66 km/h. The fire danger index (FWI) reached 4, 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: 24. Their median duration was 1 day and their median area 134 ha; 0 % went past 1,000 ha. None of its 24 twins burned more. The weather on the first day does not explain everything: the wind in the following days, the fuel and the firefighting also count. All of them had rain in the ten days after the end: the first rainy day brought a median of 4.8 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.

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; 2 polygons grouped in this page.
  • Dates adjusted with the VIIRS detections inside the perimeter, which said 19 February 2025 to 22 February 2025. 36 Suomi-NPP VIIRS detections on those dates.
  • We have not matched this page with any official record.
  • Checked against news and agencies: 4 confirmed sources.
  • Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.
  • Built-up area and population come from the JRC Global Human Settlement Layer (epoch 2025, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.

How we build fire pages: methodology

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.
