Siracusa fire, 11 July 2017 Siracusa, Noto, Canicattini Bagni

Out · last detection 13 Jul 2017, 12:17 UTC

The fire started on 11 July 2017 in Siracusa, Italy, and satellites saw it burning for 3 days. Copernicus mapped a burnt perimeter of 193 hectares from satellite imagery, spread across 3 municipalities.

It is the 31th largest in Siracusa since 2016 (of 57 with a page). Number 176 in Italy in 2017, of 361.

The power measured by the satellite is low (22.5 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Frequently asked questions

How long did the Siracusa fire last?
Copernicus dates it between 11 July 2017 and 13 July 2017: 3 days between the first and last image with fire.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 193 hectares (1.9 km²). Official national figures may differ.
Which municipalities burned?
The fire entered 3 municipalities: Siracusa (155 ha, 0.8 %); Noto (35 ha, 0.1 %); Canicattini Bagni (2 ha, 0.2 %).
Did the fire reach a town?
The closest fire to a town centre came within 4.4 km of Canicattini Bagni. 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 38.1 °C, humidity dropped to 13 % and gusts hit 46 km/h. The fire danger index (FWI) reached 58, class Extreme.
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.
