Caltabellotta fire, July 2023 Caltabellotta
The fire started on 18 July 2023 in Caltabellotta, Italy, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 205 hectares from satellite imagery, spread across a single municipality.
It is the 124th largest in Agrigento since 2016 (of 289 with a page). Number 103 in Italy in 2023, of 207.
The power measured by the satellite is low (17.6 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

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.

The smoke
CAMS · CopernicusOn 21 July 2023 the air beside the fire reached 22 µg/m³ of PM2.5. That day averaged 18: 1.2 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Caltabellotta fire last?
- Copernicus dates it between 18 July 2023 and 18 July 2023: 1 day between the first and last image with fire.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 205 hectares (2.0 km²). Official national figures may differ.
- Which municipalities burned?
- The fire only entered Caltabellotta (206 ha, 1.7 %).
- Did the fire reach a town?
- The fire started in Caltabellotta and came within 2.0 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 34.5 °C, humidity dropped to 25 % and gusts hit 30 km/h. The fire danger index (FWI) reached 33, 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. 6 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.
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.
