Isili fire, July 2024 Isili

Out · last measured on 29 Jul 2024

The fire started on 29 July 2024 in Isili, Italy, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 377 hectares from satellite imagery, spread across a single municipality.

It is the 9th largest in Sud Sardegna since 2016 (of 37 with a page). Number 16 in Italy in 2024, of 112.

We have the Copernicus perimeter for this fire, but the VIIRS sensors did not capture it in enough detail: no day-by-day evolution, but the split by municipality is there.

Official record

According to CFVA Sardegna, this fire started on 28 July 2024 and burned 360 ha (the satellite measured 377 ha).

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 Isili fire last?
Copernicus dates it between 29 July 2024 and 29 July 2024: 1 day between the first and last image with fire.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 377 hectares (3.8 km²). Official national figures may differ.
Which municipalities burned?
The fire only entered Isili (377 ha, 5.6 %).
Did the fire reach a town?
The closest fire to a town centre came within 1.0 km of Isili. 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 36.1 °C, humidity dropped to 24 % and gusts hit 30 km/h. The fire danger index (FWI) reached 32, 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.

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.

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.
