Casteltermini fire, 1 September 2022 Casteltermini
The fire started on 1 September 2022 in Casteltermini, Italy, and satellites saw it burning for 3 days. Copernicus mapped a burnt perimeter of 133 hectares from satellite imagery, spread across a single municipality.
It is the 211th largest in Agrigento since 2016 (of 289 with a page). Number 118 in Italy in 2022, of 161.
The power measured by the satellite is low (9.7 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

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 3 days without rain (1 mm or more) when it started.
This area had burned before
50% of the perimeter overlaps earlier fires recorded since 2016: 67 ha in 2019, 14 ha in 2021. Part of it burned more than once, so the yearly figures add up to more than the 67 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 1 September 2022 to 3 September 2022 (3 days). The perimeter dates it from 1 September 2022 to 1 September 2022.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 133 hectares (1.3 km²). Official national figures may differ.
- Which municipalities burned?
- The fire only entered Casteltermini (134 ha, 1.3 %).
- Did the fire reach a town?
- The fire started in Casteltermini and came within 3.9 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 31.1 °C, humidity dropped to 50 % and gusts hit 45 km/h. The fire danger index (FWI) reached 17, class Moderate.
- 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 adjusted with the VIIRS detections inside the perimeter, which said 1 September 2022 to 1 September 2022. 2 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.
