Lena fire, November 2022 Lena
The fire started on 12 November 2022 in Lena, Spain, and satellites saw it burning for 2 days. Copernicus mapped a burnt perimeter of 158 hectares from satellite imagery, spread across a single municipality. According to EGIF (MITECO), it was detected on 12 November 2022 at 12:45 and declared extinguished on 14 November 2022.
It is the 110th largest in Asturias since 2016 (of 225 with a page). Number 124 in Spain in 2022, of 196.
The power measured by the satellite is low (26.0 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

The weather it burned in
It had gone 2 days without rain (1 mm or more) when it started. Rain came after the fire: 8.2 mm on 14 Nov.
This area had burned before
33% of the perimeter overlaps earlier fires recorded since 2016: 52 ha in 2020.

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 12 November 2022 and 13 November 2022: 2 days between the first and last image with fire. According to EGIF (MITECO), it was detected on 12 November 2022 at 12:45 and declared extinguished on 14 November 2022.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 158 hectares (1.6 km²). Official national figures may differ.
- Which municipalities burned?
- The fire only entered Lena (158 ha, 0.5 %).
- Did the fire reach a town?
- The closest fire to a town centre came within 4.2 km of Lena. 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 17.4 °C, humidity dropped to 51 % and gusts hit 48 km/h. The fire danger index (FWI) reached 2, 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.

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.
