The fire started on 15 October 2017 in Cangas del Narcea, Spain, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 116 hectares from satellite imagery, spread across a single municipality. According to EGIF (MITECO), the largest of the 3 recorded fires was detected on 15 October 2017 at 06:06 and declared extinguished on 17 October 2017.
It is the 183th largest in Asturias since 2016 (of 225 with a page). Number 130 in Spain in 2017, of 144.
Perimeter published by EFFIS (Copernicus).
EGIF (MITECO): 117 ha (matched records: 3). Difference between the page and the official record: −0.8%. Matched on 8 November 2026.
15 Oct 2017 to 15 Oct 2017: first and last day with fire on the page.
EGIF (MITECO) declared the fire extinguished on 17 October 2017. Satellites may still see smouldering spots afterwards.
Alert according to EGIF (MITECO): 15 October 2017 at 06:06. Official cause: arson.
First day with fire on the page (satellite or perimeter): 15 October 2017.
VIIRS detections at 375 m. Most intense hotspot: 54 MW.
There is no official record to compare with. Each hotspot is a pixel detected in one satellite pass, not a separate fire.
Total radiative power on 15 October 2017; hotspots that day: 10.
Fire radiative power (FRP) measures the energy the fire gives off when the satellite passes. Added up by day, it compares intensity, not area.
Fire Weather Index (Canadian system) computed by WorldFires for the day the fire started. Consecutive days without rain before: 14.
This is an index computed from weather model data, not a measurement of the fire nor an official warning. Danger warnings are issued by each country’s authority. Emergency number and official warnings
High of 26.2 °C and minimum humidity of 27% on 15 October 2017; gusts of 49 km/h on 15 October 2017.
These are model values for a cell of about 25 km, not from a weather station: they may differ from what was measured on the ground.
This page’s change log has been kept since 24 October 2026: every night what it publishes is compared and the difference is logged. Anything earlier is reconstructed from each source’s date and marked as reconstructed.
Every night a snapshot of what the page shows is saved. If anything changes, it appears in the list as a log entry.
A version keeps the area, dates, name and official record; the area as it was logged (changes under 2% are not logged). The map, hotspots and weather always show today’s data.

Fire radiative power detected each day, in megawatts, and number of hotspots. The magenta bar marks the peak day.
It had gone 14 days without rain (1 mm or more) when it started. Rain came after the fire: 2.0 mm on 16 Oct.
No earlier perimeters overlap this fire since 2016, when the satellite record begins.
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.
According to EGIF (MITECO), 3 fires started inside this perimeter on these dates, totalling 117 ha (the satellite measured 116 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.
Total according to EGIF (MITECO): 117 ha, 101 % of the 116 ha in the satellite perimeter.

It started with an FWI of 16.8, a minimum humidity of 27% and 14 days without rain. Fires in the area that started in weather like this since 2016: 35.
First rain (1 mm or more) after it ended: 1.0 mm on 24 Apr.
First rain (1 mm or more) after it ended: 11.1 mm on 13 Oct.
First rain (1 mm or more) after it ended: 1.4 mm on 23 Jul.
First rain (1 mm or more) after it ended: 8.7 mm on 7 Apr.
First rain (1 mm or more) after it ended: 4.4 mm on 4 Sept.
It stayed below its twins: 116 ha against a median of 209 ha. It lasted 1 day, against 2 days.
In 6 of 35, not even 1 mm fell in the ten days after the end: they went out without rain. In the rest, the first rainy day brought a median of 3.8 mm.
This is a bank of analogues: it shows what usually happens, not what will happen. With fewer than 15 twins we give no figures. How we calculate it
It was considered over on 15 Oct, and on 16 Oct 2.0 mm fell. We do not know whether the rain or the firefighters put it out. Twins with rain when they ended: 29 of 35, with a median of 3.8 mm.

Drag the line to compare the same ground before the fire and after it.
If the day is cloudy, change the date: each satellite passes once a day. In false colour the burnt ground looks brown or red.
On 16 October 2017 the air beside the fire reached 144 µg/m³ of PM2.5. That day averaged 73: 4.8 times the WHO daily guideline (15).

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.
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.
