Castro Laboreiro e Lamas de Mouro fire, April 2017 Castro Laboreiro e Lamas de Mouro

Out · last detection 13 Apr 2017, 02:43 UTC

The fire started on 12 April 2017 in Castro Laboreiro e Lamas de Mouro, Portugal, and satellites saw it burning for 2 days. Copernicus mapped a burnt perimeter of 146 hectares from satellite imagery, spread across a single freguesia.

This entry is most likely a pasture burn or a prescribed winter burn in northern Portugal, not a wildfire. In these hills scrub is burnt to renew grazing, and this fire is not in the ICNF register of rural fires. This is our assumption, based on the time of year and the lack of an official record; it is not confirmed. That is why it is left out of the wildfire rankings.

The power measured by the satellite is low (7.1 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

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 Castro Laboreiro e Lamas de Mouro fire last?
Copernicus dates it between 12 April 2017 and 13 April 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 146 hectares (1.5 km²). Official national figures may differ.
Which freguesias burned?
The fire only entered Castro Laboreiro e Lamas de Mouro (146 ha, 1.4 %).
Did the fire reach a town?
The fire started in Castro Laboreiro e Lamas de Mouro and came within 1.4 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 18.4 °C, humidity dropped to 35 % and gusts hit 36 km/h. The fire danger index (FWI) reached 14, class Moderate.
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: 21. Their median duration was 2 days and their median area 296 ha; 19 % went past 1,000 ha. In 5 of 21, 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 9.9 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.

How we know this
  • Perimeter: EFFIS (Copernicus), mapped on satellite imagery.
  • Dates from the perimeter: the VIIRS detections inside it did not change them. 13 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.
  • Probably a vegetation burn: not counted in the totals.

How we build fire pages: methodology

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.
