Lena fire, 24 February 2020 Lena
The fire started on 24 February 2020 in Lena, Spain, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 130 hectares from satellite imagery, spread across a single municipality.
It is the 146th largest in Asturias since 2016 (of 225 with a page). Number 71 in Spain in 2020, of 89.

The weather it burned in
It had gone 6 days without rain (1 mm or more) when it started. Rain came after the fire: 2.8 mm on 25 Feb.
This area had burned before
No earlier perimeters overlap this fire since 2016, when the satellite record begins.
What happened to each town

130 ha reached on 24 Feb0.4 %
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.

Land cover inside the perimeter according to Corine Land Cover, as reported by Copernicus.
Several official records match this area
According to EGIF (MITECO), 2 fires started inside this perimeter on these dates, totalling 70 ha (the satellite measured 130 ha). The two figures differ a lot, so these may not be exactly the same fire: take them as nearby records.
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.

- 2 Lena Llanos de Someron 23 February 2020 · 23:58 6 ha · extinguished on 24 February 2020 · cause: arson
Total according to EGIF (MITECO): 70 ha, 54 % of the 130 ha in the satellite perimeter.

The weather day by day
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.

Frequently asked questions
- How long did the Lena fire last?
- Copernicus dates it between 24 February 2020 and 24 February 2020: 1 day between the first and last image with fire.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 130 hectares (1.3 km²). Official national figures may differ.
- Which municipalities burned?
- The fire only entered Lena (130 ha, 0.4 %).
- Did the fire reach a town?
- The fire started in Lena and came within 2.3 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 15.4 °C, humidity dropped to 24 % and gusts hit 31 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.
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. 16 Suomi-NPP VIIRS detections on those dates.
- Compared with EGIF (MITECO): 70 official ha against 130 ha of perimeter; similar, but with reservations.
- 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 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.
