No earlier perimeters overlap this fire since 2016, when the satellite record begins.
What happened to each town
-
132 ha reached on 7 Jul1.0 %
Burnt area inside each municipality, from crossing the official perimeter with administrative boundaries. The distance is from the town centre to the nearest fire: staying a kilometre away does not mean it reached the houses.
What burned
- Broadleaved forest62 %
- Agricultural areas38 %
Land cover inside the perimeter according to Corine Land Cover, as reported by Copernicus.
Official record

Frequently asked questions
- How long did the Uta fire last?
- Copernicus dates it between 7 July 2019 and 7 July 2019: 1 day between the first and last image with fire.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 132 hectares (1.3 km²). Official national figures may differ.
- Which municipalities burned?
- The fire only entered Uta (132 ha, 1.0 %).
- Did the fire reach a town?
- The closest fire to a town centre came within 7.3 km of Uta. 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 36.6 °C, humidity dropped to 34 % and gusts hit 33 km/h. The fire danger index (FWI) reached 35, 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.

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.
