Vilariño de Conso fire, August 2017
Vilariño de Conso
Out · last detection 13 Aug 2017, 02:55 UTC
The fire started on 12 August 2017 in Vilariño de Conso, Spain, and satellites saw it burning for 2 days. Copernicus mapped a burnt perimeter of 217 hectares from satellite imagery, spread across a single municipality.
It is the 73th largest in Ourense since 2016 (of 118 with a page). Number 91 in Spain in 2017, of 144.
The power measured by the satellite is low (24.3 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Satellites pass a few times a day and cloud or smoke can hide the fire: a lack of detections is not an official extinction. Each country’s emergency service declares a fire contained or out.

Fire radiative power (FRP) measures the energy the fire gives off when the satellite passes. Added up by day, it compares intensity, not area.

Official record
Several official records match this area
According to EGIF (MITECO), 2 fires started inside this perimeter on these dates, totalling 134 ha (the satellite measured 217 ha). The two figures differ a lot, so these may not be exactly the same fire: take them as nearby records.
EGIF (MITECO) 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.
ECMWF ERA5 reanalysis at the fire location, the standard reference for past weather, and the Canadian Fire Weather Index (the same system Copernicus uses), computed by WorldFires from that data. Days after the fire run until the first rain.

How a twin is chosen
Same area: fires that have already ended, less than 250 km from this one, since 2016.
Same start: we compare the FWI on the first day, the minimum humidity that day and the run of days without rain before it. The slider sets how much they may differ.
Only pages with final weather data (ERA5 reanalysis) calculated in the same way as this fire’s; agricultural and grass burns and pages with data under review are left out.
Fires burning at the same time as this one (a week before or after) are left out: they share the same spell of weather and do not count as a precedent.
They are sorted by similarity, and the outlines of the first five are drawn.

How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 217 hectares (2.2 km²). Official national figures may differ.
Which municipalities burned?
The fire only entered Vilariño de Conso (217 ha, 1.1 %).
Did the fire reach a town?
The fire started in Vilariño de Conso and came within 1.5 km of its centre. That is the distance from the perimeter, or the nearest hotspot, to the point marking the centre; it does not mean it entered the houses.
What was the weather like?
During the fire the temperature reached 26.5 °C, humidity dropped to 27 % and gusts hit 30 km/h. The fire danger index (FWI) reached 25, class High.
Where does this data come from?
From the EFFIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Spain (geoBoundaries). It is not an official report.
How did the fires that started in similar weather in this area end?
Fires less than 250 km away that started since 2016 with a similar FWI, humidity and dry spell: 55. Their median duration was 2 days and their median area 362 ha; 16 % went past 1,000 ha. In 9 of 55, not even 1 mm fell in the ten days after the end: they went out without rain. In the rest, the first rainy day brought a median of 4.4 mm.
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.
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.

Perimeter: EFFIS (Copernicus), mapped on satellite imagery.
Dates from the perimeter: the VIIRS detections inside it did not change them. 19 Suomi-NPP VIIRS detections on those dates.
Compared with EGIF (MITECO): 134 official ha against 217 ha of perimeter; similar, but with reservations.
Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.
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 (Creative Commons Attribution 4.0 International (CC BY 4.0)). 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.
