Torre de Moncorvo fire, June 2017 Cabeça Boa, Lousa, Horta da Vilariça

Out · last detection 24 Jun 2017, 01:52 UTC

The fire started on 22 June 2017 in Cabeça Boa, Portugal, and satellites saw it burning for 3 days. Copernicus mapped a burnt perimeter of 3,233 hectares from satellite imagery, spread across 5 municipalities. According to ICNF, the largest of the 2 recorded fires was detected on 21 June 2017 at 16:45 and declared extinguished on 23 June 2017.

It is the 2th largest in Torre de Moncorvo since 2016 (of 14 with a page). Number 25 in Portugal in 2017, of 210.

The power measured by the satellite is low (26.5 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Built-up area4.0 ha
Residents≈ 150

Inside the perimeter there were about 4.0 hectares of built-up land and about 150 residents (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.

Official record

Complex of 2 fires according to ICNF

According to ICNF, 2 fires started inside this perimeter on these dates, totalling 2,971 ha (the satellite measured 3,233 ha).

ICNF 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.

Frequently asked questions

How long did the Torre de Moncorvo fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 22 June 2017 to 24 June 2017 (3 days). The perimeter dates it from 22 June 2017 to 23 June 2017. According to ICNF, the largest of the 2 recorded fires was detected on 21 June 2017 at 16:45 and declared extinguished on 23 June 2017.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 3,233 hectares (32.3 km²). Official national figures may differ.
Which municipalities burned?
The fire entered 5 municipalities: Cabeça Boa (1,829 ha, 69 %); Lousa (796 ha, 23 %); Horta da Vilariça (353 ha, 21 %); Castedo (181 ha, 10 %); Vila Nova de Foz Côa (76 ha, 0.8 %).
Did the fire reach a town?
The fire started in Cabeça Boa and reached its centre: the point marking it was inside the burnt area or less than 500 metres from it. That does not mean houses burned.
What was the weather like?
During the fire the temperature reached 31.5 °C, humidity dropped to 21 % and gusts hit 52 km/h. The fire danger index (FWI) reached 34, 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.

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 adjusted with the VIIRS detections inside the perimeter, which said 22 June 2017 to 23 June 2017. 124 Suomi-NPP VIIRS detections on those dates.
  • Compared with ICNF: 2,971 official ha against 3,233 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 2015, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.

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. Municipal boundaries come from geoBoundaries ADM3 (CC0 1.0 Universal (CC0 1.0) Public Domain Dedication). 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.
