Butera fire, 16 July 2023 Butera

Out · last detection 16 Jul 2023, 11:41 UTC

The fire started on 16 July 2023 in Butera, Italy, and satellites saw it burning for 3 days. Copernicus mapped a burnt perimeter of 107 hectares from satellite imagery, spread across a single municipality.

It is the 141th largest in Caltanissetta since 2016 (of 149 with a page). Number 193 in Italy in 2023, of 207.

The power measured by the satellite is low (10.5 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Frequently asked questions

How long did the Butera fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 16 July 2023 to 18 July 2023 (3 days). The perimeter dates it from 16 July 2023 to 16 July 2023.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 107 hectares (1.1 km²). Official national figures may differ.
Which municipalities burned?
The fire only entered Butera (108 ha, 0.4 %).
Did the fire reach a town?
The fire started in Butera and came within 1.2 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 34.5 °C, humidity dropped to 20 % and gusts hit 28 km/h. The fire danger index (FWI) reached 37, 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 adjusted with the VIIRS detections inside the perimeter, which said 16 July 2023 to 16 July 2023. 3 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.
