Miera fire, 15 February 2019 Liérganes, Miera, Santa María de Cayón
The fire started on 15 February 2019 in Miera, Spain, and satellites saw it burning for 3 days. Copernicus mapped a burnt perimeter of 159 hectares from satellite imagery, spread across 3 municipalities. According to EGIF (MITECO), the largest of the 2 recorded fires was detected on 17 February 2019 at 01:28 and declared extinguished on 17 February 2019.
It is the 106th largest in Cantabria since 2016 (of 179 with a page). Number 59 in Spain in 2019, of 102.
The power measured by the satellite is low (2.7 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

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.
People and buildings inside the perimeter
GHSL 2020Inside the perimeter there was no noticeable built-up land and almost nobody lived there (GHSL 2020, 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.

Complex of 2 fires according to EGIF (MITECO)
According to EGIF (MITECO), 2 fires started inside this perimeter on these dates, totalling 150 ha (the satellite measured 159 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.

- 2 Santa María de Cayón Esles 17 February 2019 · 21:45 74 ha · extinguished on 18 February 2019 · cause: arson
Total according to EGIF (MITECO): 150 ha, 95 % of the 159 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 Miera fire last?
- Copernicus dates it between 15 February 2019 and 17 February 2019: 3 days between the first and last image with fire. According to EGIF (MITECO), the largest of the 2 recorded fires was detected on 17 February 2019 at 01:28 and declared extinguished on 17 February 2019.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 159 hectares (1.6 km²). Official national figures may differ.
- Which municipalities burned?
- The fire entered 3 municipalities: Liérganes (127 ha, 3.4 %); Miera (30 ha, 0.9 %); Santa María de Cayón (3 ha, 0.0 %).
- Did the fire reach a town?
- The fire came within 4.0 km of the centre of Liérganes, the closest of the areas it touched. 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 18.3 °C, humidity dropped to 32 % and gusts hit 43 km/h. The fire danger index (FWI) reached 6, class 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. 6 Suomi-NPP VIIRS detections on those dates.
- Compared with EGIF (MITECO): 150 official ha against 159 ha of perimeter; they agree within 25%.
- 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 2020, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.
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.
