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 17 days without rain (1 mm or more) when it started. Rain came after the fire: 5.0 mm on 28 Jul.
This area had burned before
29% of the perimeter overlaps earlier fires recorded since 2016: 551 ha in 2016, 222 ha in 2019, 324 ha in 2023, 37 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 878 ha that had burned before.

The smoke
CAMS · CopernicusOn 23 July 2026 the air beside the fire reached 28 µg/m³ of PM2.5. That day averaged 20: 1.3 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Resuttano fire last?
- The official perimeter only gives the start date (21 July 2026). The end comes from the heat detections inside the perimeter: it burned until 23 July 2026 (3 days from 21 July 2026), the last day with detections before more than 10 days in a row without any, so it is approximate.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 2,999 hectares (30.0 km²). Official national figures may differ.
- Which municipalities burned?
- The fire entered 6 municipalities: Resuttano (1,069 ha, 28 %); Alimena (555 ha, 9.3 %); Petralia Sottana (438 ha, 2.5 %); Polizzi Generosa (393 ha, 2.9 %); Bompietro (325 ha, 7.7 %); Castellana Sicula (224 ha, 3.1 %).
- Did the fire reach a town?
- The fire started in Resuttano and came within 0.9 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 41.7 °C, humidity dropped to 8 % and gusts hit 46 km/h. The fire danger index (FWI) reached 78, class Very extreme.
- 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.
- The official perimeter has no end date: the end is the last day with VIIRS detections inside the perimeter before a gap of more than 10 days (150 days at most), so it is approximate. 53 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.
