Cabril fire, October 2017 Vilar da Veiga, Cabril
Out · last detection 15 Oct 2017, 03:15 UTC
The fire started on 14 October 2017 in Cabril, Portugal, and satellites saw it burning for 2 days. Copernicus mapped a burnt perimeter of 462 hectares from satellite imagery, spread across 2 freguesias.
It is the 10th largest in Montalegre since 2016 (of 65 with a page). Number 96 in Portugal in 2017, of 211.

Inside the perimeter there were about 0.13 hectares of built-up land and almost nobody lived there (GHSL 2015, 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.

It was 1.8 times larger than the median of its twins and lasted 2 days, against 2 days.
Only 10 of its 31 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. In 13 of 31, 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 4.6 mm.

It was considered over on 15 Oct, and on 16 Oct 4.7 mm fell. We do not know whether the rain or the firefighters put it out. Twins with rain when they ended: 18 of 31, with a median of 4.6 mm.

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 Cabril fire last?
- Copernicus dates it between 14 October 2017 and 15 October 2017: 2 days between the first and last image with fire.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 462 hectares (4.6 km²). Official national figures may differ.
- Which freguesias burned?
- The fire entered 2 freguesias: Vilar da Veiga (252 ha, 3.2 %); Cabril (211 ha, 2.8 %).
- Did the fire reach a town?
- The fire started in Cabril and came within 1.8 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 25.9 °C, humidity dropped to 28 % and gusts hit 58 km/h. The fire danger index (FWI) reached 35, class High.
- Where does this data come from?
- From the EFFIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Portugal (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: 31. Their median duration was 2 days and their median area 251 ha; 19 % went past 1,000 ha. Only 10 of its 31 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. In 13 of 31, 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 4.6 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.
Report an error
How we know this
- Perimeter: EFFIS (Copernicus), mapped on satellite imagery.
- Dates from the perimeter: the VIIRS detections inside it did not change them. 64 Suomi-NPP VIIRS detections on those dates.
- We have not matched this page with any official record.
- 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 2015, 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. Freguesia boundaries come from geoBoundaries ADM3 (CC0 1.0 Universal (CC0 1.0) Public Domain Dedication). The area per freguesia is computed by WorldFires by crossing the perimeter with those boundaries, so it may differ slightly from each country’s official figure.
