Burnt area inside each municipality, from crossing the official perimeter with administrative boundaries. The distance runs from the point marking the centre of each area to the nearest fire: staying a kilometre away does not mean it reached the houses.

Land cover inside the perimeter according to Corine Land Cover, as reported by Copernicus.
People and buildings inside the perimeter
GHSL 2020Inside the perimeter there were about 2.2 hectares of built-up land and almost nobody lived there (GHSL 2020, satellite-based estimate).
This is an estimate on 100 m cells, made from satellite imagery and census data: it does not mean that homes burned or that anyone was harmed. The perimeter also contains land that never burned.

Complex of 2 fires according to ICNF
According to ICNF, 2 fires started inside this perimeter on these dates, totalling 385 ha (the satellite measured 369 ha).
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.

- 2 Mirandela Mirandela 6 August 2020 · 11:24 374 ha · extinguished on 6 August 2020 · cause: negligence
Total according to ICNF: 385 ha, 104 % of the 369 ha in the satellite perimeter.

The weather day by day
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.

Frequently asked questions
- How long did the Mirandela fire last?
- Copernicus dates it between 6 August 2020 and 6 August 2020: 1 day between the first and last image with fire. According to ICNF, the largest of the 2 recorded fires was detected on 6 August 2020 at 11:24 and declared extinguished on 6 August 2020.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 369 hectares (3.7 km²). Official national figures may differ.
- Which municipalities burned?
- The fire entered 3 municipalities: Suçães (270 ha, 7.4 %); Mirandela (99 ha, 3.0 %); Cabanelas (1 ha, 0.0 %).
- Did the fire reach a town?
- The fire started in Mirandela and came within 1.3 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 39.0 °C, humidity dropped to 19 % and gusts hit 41 km/h. The fire danger index (FWI) reached 46, 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.

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.

How we know this
- Perimeter: EFFIS (Copernicus), mapped on satellite imagery.
- Dates from the perimeter: the VIIRS detections inside it did not change them. 9 Suomi-NPP VIIRS detections on those dates.
- Compared with ICNF: 385 official ha against 369 ha of perimeter; they agree within 25%.
- Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.
- Built-up area and population come from the JRC Global Human Settlement Layer (epoch 2020, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.
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.
