Baião fire, 11 August 2016 Gove, Santa Cruz do Douro e São Tomé de Covelas

Out · last detection 12 Aug 2016, 02:19 UTC

The fire started on 11 August 2016 in Gove, Portugal, and satellites saw it burning for 2 days. Copernicus mapped a burnt perimeter of 233 hectares from satellite imagery, spread across 2 municipalities. According to ICNF, it was detected on 11 August 2016 at 00:12 and declared extinguished on 12 August 2016.

It is the 9th largest in Baião since 2016 (of 14 with a page). Number 100 in Portugal in 2016, of 179.

The power measured by the satellite is low (26.4 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Frequently asked questions

How long did the Baião fire last?
Copernicus dates it between 11 August 2016 and 12 August 2016: 2 days between the first and last image with fire. According to ICNF, it was detected on 11 August 2016 at 00:12 and declared extinguished on 12 August 2016.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 233 hectares (2.3 km²). Official national figures may differ.
Which municipalities burned?
The fire entered 2 municipalities: Gove (154 ha, 14 %); Santa Cruz do Douro e São Tomé de Covelas (80 ha, 5.0 %).
Did the fire reach a town?
The closest fire to a town centre came within 1.0 km of Gove. 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 30.0 °C, humidity dropped to 26 % and gusts hit 51 km/h. The fire danger index (FWI) reached 41, 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.

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.
