Frequently asked questions

How long did the Proença-a-Nova fire last?
Copernicus dates it between 7 September 2016 and 7 September 2016: 1 day between the first and last image with fire. According to ICNF, it was detected on 7 September 2016 at 13:59 and declared extinguished on 8 September 2016.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 1,093 hectares (10.9 km²). Official national figures may differ.
Which municipalities burned?
The fire entered 2 municipalities: Proença a Nova e Peral (599 ha, 3.5 %); União das freguesias de Sobreira Formosa e Alvito da Beira (495 ha, 4.2 %).
Did the fire reach a town?
The closest fire to a town centre came within 1.0 km of Proença a Nova e Peral. 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 33.0 °C, humidity dropped to 25 % and gusts hit 43 km/h. The fire danger index (FWI) reached 52, class Extreme.
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.

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.
