Marco fire, September 2024 Marco, Paredes de Viadores e Manhuncelos, Soalhães

Out · last detection 18 Sept 2024, 02:37 UTC

The fire started on 17 September 2024 in Marco, Portugal, and satellites saw it burning for 2 days. Copernicus mapped a burnt perimeter of 164 hectares from satellite imagery, spread across 3 municipalities.

It is the 11th largest in Marco de Canaveses since 2016 (of 14 with a page). Number 58 in Portugal in 2024, of 69.

The power measured by the satellite is low (29.0 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

37% of the perimeter overlaps earlier fires recorded since 2016: 57 ha in 2016, 7 ha in 2020.

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 2025
Built-up area3.1 ha
Residents≈ 150

Inside the perimeter there were about 3.1 hectares of built-up land and about 150 residents (GHSL 2025, 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. The GHSL 2025 epoch is a projection made from 2020 and earlier data.

Frequently asked questions

How long did the Marco fire last?
Copernicus dates it between 17 September 2024 and 18 September 2024: 2 days between the first and last image with fire.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 164 hectares (1.6 km²). Official national figures may differ.
Which municipalities burned?
The fire entered 3 municipalities: Marco (148 ha, 8.5 %); Paredes de Viadores e Manhuncelos (14 ha, 1.1 %); Soalhães (2 ha, 0.1 %).
Did the fire reach a town?
The fire started in Marco and came within 0.9 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 27.5 °C, humidity dropped to 22 % and gusts hit 57 km/h. The fire danger index (FWI) reached 49, 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.

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.

How we know this
  • Perimeter: EFFIS (Copernicus), mapped on satellite imagery.
  • Dates from the perimeter: the VIIRS detections inside it did not change them. 13 Suomi-NPP VIIRS detections on those dates.
  • We have not matched this page with any official record.
  • 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 2025, 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.
