Cesarò fire, July 2021 Troina, Cerami, Cesarò

Out · last detection 31 Jul 2021, 00:25 UTC

The fire started on 30 July 2021 in Cesarò, Italy, and satellites saw it burning for 2 days. Copernicus mapped a burnt perimeter of 461 hectares from satellite imagery, spread across 3 municipalities.

It is the 13th largest in Messina since 2016 (of 70 with a page). Number 54 in Italy in 2021, of 291.

The power measured by the satellite is low (2.3 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 is from the town centre to the nearest fire: staying a kilometre away does not mean it reached the houses.

Frequently asked questions

How long did the Cesarò fire last?
Copernicus dates it between 30 July 2021 and 31 July 2021: 2 days between the first and last image with fire.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 461 hectares (4.6 km²). Official national figures may differ.
Which municipalities burned?
The fire entered 3 municipalities: Troina (201 ha, 1.2 %); Cerami (170 ha, 1.8 %); Cesarò (91 ha, 0.4 %).
Did the fire reach a town?
The closest fire to a town centre came within 4.2 km of Troina. 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 32.0 °C, humidity dropped to 25 % and gusts hit 42 km/h. The fire danger index (FWI) reached 32, 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.
