Sarroch fire, April 2024 Sarroch

Out · last detection 18 Apr 2024, 02:06 UTC

The fire started on 17 April 2024 in Sarroch, Italy, and satellites saw it burning for 2 days. Copernicus mapped a burnt perimeter of 170 hectares from satellite imagery, spread across a single municipality.

Number 55 in Italy in 2024, of 112.

The power measured by the satellite is low (15.2 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Official record

According to CFVA Sardegna, this fire started on 17 April 2024 and burned 156 ha (the satellite measured 170 ha).

Frequently asked questions

How long did the Sarroch fire last?
Copernicus dates it between 17 April 2024 and 18 April 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 170 hectares (1.7 km²). Official national figures may differ.
Which municipalities burned?
The fire only entered Sarroch (170 ha, 2.5 %).
Did the fire reach a town?
The fire started in Sarroch and came within 1.9 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 17.2 °C, humidity dropped to 41 % and gusts hit 71 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 Italy (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. 11 Suomi-NPP VIIRS detections on those dates.
  • Compared with CFVA Sardegna: 156 official ha against 170 ha of perimeter; they agree within 25%.
  • Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.

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 ADM4 (Creative Commons Attribution 3.0 License). 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.
