Naro fire, July 2021 Naro

Out · last detection 1 Jul 2021, 12:49 UTC

The fire started on 1 July 2021 in Naro, Italy, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 134 hectares from satellite imagery, spread across a single municipality.

It is the 209th largest in Agrigento since 2016 (of 289 with a page). Number 212 in Italy in 2021, of 291.

The power measured by the satellite is low (3.9 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

It had gone 5 days without rain (1 mm or more) when it started.

This area had burned before

67% of the perimeter overlaps earlier fires recorded since 2016: 55 ha in 2016, 20 ha in 2018, 15 ha in 2019, 71 ha in 2020. Part of it burned more than once, so the yearly figures add up to more than the 90 ha that had burned before.

Frequently asked questions

How long did the Naro fire last?
Copernicus dates it between 1 July 2021 and 1 July 2021: 1 day between the first and last image with fire.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 134 hectares (1.3 km²). Official national figures may differ.
Which municipalities burned?
The fire only entered Naro (134 ha, 0.6 %).
Did the fire reach a town?
The closest fire to a town centre came within 5.8 km of Naro. 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 34.8 °C, humidity dropped to 30 % and gusts hit 34 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.

Satellite cross-check

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.
