Out · last detection 11 Aug 2016, 02:37 UTC

The fire started on 10 August 2016 in Gestaçô, Portugal, and satellites saw it burning for 2 days. Copernicus mapped a burnt perimeter of 153 hectares from satellite imagery, spread across a single municipality.

Official record

Several official records match this area

According to ICNF, 2 fires started inside this perimeter on these dates, totalling 207 ha (the satellite measured 153 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 Baião fire last?
Copernicus dates it between 10 August 2016 and 11 August 2016: 2 days between the first and last image with fire.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 153 hectares (1.5 km²). Official national figures may differ.
Which municipalities burned?
The fire only entered Gestaçô (153 ha, 11 %).
Did the fire reach a town?
The closest fire to a town centre came within 1.4 km of Gestaçô. 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 26.8 °C, humidity dropped to 26 % and gusts hit 62 km/h. The fire danger index (FWI) reached 43, class Very 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.

We will only use your email to reply about this report. Privacy. This is not an emergency service: if there is a fire now, call 112.

How we know this
  • Perimeter: EFFIS (Copernicus), mapped on satellite imagery.
  • Dates from the perimeter: the VIIRS detections inside it did not change them. 11 Suomi-NPP VIIRS detections on those dates.
  • Compared with ICNF: 207 official ha against 153 ha of perimeter; similar, but with reservations.
  • Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.

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.
