Naro fire, 20 June 2021 Ravanusa, Naro, Sommatino
The fire started on 20 June 2021 in Naro, Italy, and satellites saw it burning for 7 days. Copernicus mapped a burnt perimeter of 895 hectares from satellite imagery, spread across 4 municipalities.
It is the 10th largest in Agrigento since 2016 (of 289 with a page). Number 19 in Italy in 2021, of 291.
The power measured by the satellite is low (5.3 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Burnt area inside each municipality, from crossing the official perimeter with administrative boundaries. The distance runs from the point marking the centre of each area to the nearest fire: staying a kilometre away does not mean it reached the houses.

Land cover inside the perimeter according to Corine Land Cover, as reported by Copernicus.
People and buildings inside the perimeter
GHSL 2020Inside the perimeter there were about 0.56 hectares of built-up land and almost nobody lived there (GHSL 2020, satellite-based estimate).
This is an estimate on 100 m cells, made from satellite imagery and census data: it does not mean that homes burned or that anyone was harmed. The perimeter also contains land that never burned.

Frequently asked questions
- How long did the Naro fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 20 June 2021 to 26 June 2021 (7 days). The perimeter dates it from 23 June 2021 to 26 June 2021.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 895 hectares (9.0 km²). Official national figures may differ.
- Which municipalities burned?
- The fire entered 4 municipalities: Ravanusa (440 ha, 8.9 %); Naro (238 ha, 1.2 %); Sommatino (156 ha, 4.5 %); Riesi (63 ha, 1.0 %).
- Did the fire reach a town?
- The fire came within 1.8 km of the centre of Ravanusa, the closest of the areas it touched. 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 38.8 °C, humidity dropped to 26 % and gusts hit 37 km/h. The fire danger index (FWI) reached 38, 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 23 June 2021 to 26 June 2021. 12 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.
- Built-up area and population come from the JRC Global Human Settlement Layer (epoch 2020, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.
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.
