It had gone 33 days without rain (1 mm or more) when it started.

This area had burned before

64% of the perimeter overlaps earlier fires recorded since 2016: 30 ha in 2016, 1,275 ha in 2017, 124 ha in 2020. Part of it burned more than once, so the yearly figures add up to more than the 1,294 ha that had burned before.

How big is it?

It burned the equivalent of 1.3% of the area of London (20 km² against 1,583 km²).

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.

Built-up area0.37 ha
Residents< 20

Inside the perimeter there were about 0.37 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 Enna fire last?
Copernicus dates it between 30 July 2021 and 3 August 2021: 5 days between the first and last image with fire.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 2,024 hectares (20.2 km²). Official national figures may differ.
Which municipalities burned?
The fire entered 2 municipalities: Aidone (1,230 ha, 5.8 %); Enna (797 ha, 2.2 %).
Did the fire reach a town?
The fire started in Enna and came within 2.5 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 35.1 °C, humidity dropped to 25 % and gusts hit 46 km/h. The fire danger index (FWI) reached 45, 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. 155 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.
