Casteltermini fire, 8 October 2023 Casteltermini, Cammarata
The fire started on 8 October 2023 in Casteltermini, Italy, and satellites saw it burning for 7 days. Copernicus mapped a burnt perimeter of 646 hectares from satellite imagery, spread across 2 municipalities.
It is the 21th largest in Agrigento since 2016 (of 289 with a page). Number 27 in Italy in 2023, of 207.
The power measured by the satellite is low (22.9 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Where it burned
How it evolved, day by day
Fire radiative power detected each day, in megawatts, and number of hotspots. The magenta bar marks the peak day.
The weather it burned in
It had gone 14 days without rain (1 mm or more) when it started. Rain came after the fire: 1.6 mm on 21 Oct.
This area had burned before
27% of the perimeter overlaps earlier fires recorded since 2016: 93 ha in 2017, 29 ha in 2019, 59 ha in 2020, 7 ha in 2021, 17 ha in 2022. Part of it burned more than once, so the yearly figures add up to more than the 175 ha that had burned before.

Frequently asked questions
- How long did the Casteltermini fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 8 October 2023 to 14 October 2023 (7 days). The perimeter dates it from 8 October 2023 to 12 October 2023.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 646 hectares (6.5 km²). Official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Casteltermini (384 ha, 3.8 %); Cammarata (263 ha, 1.4 %).
- Did the fire reach a town?
- The fire started in Casteltermini and came within 3.2 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 28.5 °C, humidity dropped to 26 % and gusts hit 28 km/h. The fire danger index (FWI) reached 30, 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; 2 polygons grouped in this page.
- Dates adjusted with the VIIRS detections inside the perimeter, which said 8 October 2023 to 12 October 2023. 25 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.
