Bompensiere fire, August 2017 Bompensiere, Racalmuto
The fire started on 29 August 2017 in Bompensiere, Italy, and satellites saw it burning for 2 days. Copernicus mapped a burnt perimeter of 172 hectares from satellite imagery, spread across 2 municipalities.
It is the 82th largest in Caltanissetta since 2016 (of 149 with a page). Number 203 in Italy in 2017, of 361.
The power measured by the satellite is low (10.1 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

The smoke
CAMS · CopernicusOn 31 August 2017 the air beside the fire reached 21 µg/m³ of PM2.5. That day averaged 15: 1.0 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Bompensiere fire last?
- Copernicus dates it between 29 August 2017 and 30 August 2017: 2 days between the first and last image with fire.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 172 hectares (1.7 km²). Official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Bompensiere (153 ha, 7.6 %); Racalmuto (20 ha, 0.3 %).
- Did the fire reach a town?
- The closest fire to a town centre came within 1.5 km of Bompensiere. 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 35.4 °C, humidity dropped to 19 % and gusts hit 33 km/h. The fire danger index (FWI) reached 42, class Very 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. 8 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.
