How long did the Abrantes fire last?

Copernicus dates it between 23 August 2016 and 25 August 2016: 3 days between the first and last image with fire. According to ICNF, it was detected on 23 August 2016 at 15:51 and declared extinguished on 24 August 2016.

How much area did it burn?

The perimeter Copernicus measured from satellite imagery is 2,185 hectares (21.8 km²). Official national figures may differ.

Which municipalities burned?

The fire entered 6 municipalities: Sardoal (817 ha, 27 %); Carvalhal (744 ha, 42 %); Abrantes (São Vicente e São João) e Alferrarede (378 ha, 5.9 %); Fontes (126 ha, 4.4 %); Santiago de Montalegre (102 ha, 6.0 %); Aldeia do Mato e Souto (21 ha, 0.5 %).

Did the fire reach a town?

The closest fire to a town centre came within 0.3 km of Carvalhal. 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 35.6 °C, humidity dropped to 27 % and gusts hit 41 km/h. The fire danger index (FWI) reached 51, 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.

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.
