Built-up area< 0.1 ha
Residents< 20

Inside the perimeter there was no noticeable built-up land and almost nobody lived there (GHSL 2020, 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

Several official records match this area

According to ICNF, 3 fires started inside this perimeter on these dates, totalling 642 ha (the satellite measured 339 ha). The two figures differ a lot, so these may not be exactly the same fire: take them as nearby records.

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 Vila Verde fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 29 September 2018 to 3 October 2018 (5 days). The perimeter dates it from 2 October 2018 to 3 October 2018.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 339 hectares (3.4 km²). Official national figures may differ.
Which municipalities burned?
The fire entered 5 municipalities: União das freguesias de Crasto, Ruivos e Grovelas (176 ha, 18 %); Vade (97 ha, 6.2 %); Boalhosa (41 ha, 19 %); Ribeira do Neiva (17 ha, 0.5 %); Boivães (8 ha, 2.4 %).
Did the fire reach a town?
The fire reached the centre of Boalhosa: 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 26.2 °C, humidity dropped to 16 % and gusts hit 31 km/h. The fire danger index (FWI) reached 28, 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 2 October 2018 to 3 October 2018. 33 Suomi-NPP VIIRS detections on those dates.
  • Compared with ICNF: 642 official ha against 339 ha of perimeter; similar, but with reservations.
  • 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 2020, 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.
