Sabrosa fire, 24 August 2017 Paços, Gouvinhas, Provesende, Gouvães do Douro e São Cristóvão do Douro

Out · last measured on 24 Aug 2017

The fire started on 24 August 2017 in Paços, Portugal, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 307 hectares from satellite imagery, spread across 3 municipalities. According to ICNF, it was detected on 22 August 2017 at 15:07 and declared extinguished on 24 August 2017.

Number 115 in Portugal in 2017, of 210.

We have the Copernicus perimeter for this fire, but the VIIRS sensors did not capture it in enough detail: no day-by-day evolution, but the split by municipality is there.

Burnt area inside each municipality, from crossing the official perimeter with administrative boundaries. The distance is from the town centre to the nearest fire: staying a kilometre away does not mean it reached the houses.

Frequently asked questions

How long did the Sabrosa fire last?
Copernicus dates it between 24 August 2017 and 24 August 2017: 1 day between the first and last image with fire. According to ICNF, it was detected on 22 August 2017 at 15:07 and declared extinguished on 24 August 2017.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 307 hectares (3.1 km²). Official national figures may differ.
Which municipalities burned?
The fire entered 3 municipalities: Paços (252 ha, 15 %); Gouvinhas (56 ha, 3.8 %); Provesende, Gouvães do Douro e São Cristóvão do Douro (0 ha, 0.0 %).
Did the fire reach a town?
The closest fire to a town centre came within 1.7 km of Provesende, Gouvães do Douro e São Cristóvão do Douro. That is the distance to the perimeter or nearest hotspot; it does not mean it entered the houses.
What was the weather like?
During the fire the temperature reached 25.6 °C, humidity dropped to 36 % and gusts hit 35 km/h. The fire danger index (FWI) reached 32, 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.

Emergency number: 112

Satellite cross-check

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.

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.
