Imperia fire, September 2016 Imperia, Pontedassio

Out · last measured on 7 Sept 2016

The fire started on 7 September 2016 in Imperia, Italy, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 155 hectares from satellite imagery, spread across 2 municipalities.

Number 53 in Italy in 2016, of 78.

We have the Copernicus perimeter for this fire, but the VIIRS sensors did not capture it in enough detail: no day-by-day evolution, but the split by municipality is there.

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 Imperia fire last?
Copernicus dates it between 7 September 2016 and 7 September 2016: 1 day between the first and last image with fire.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 155 hectares (1.6 km²). Official national figures may differ.
Which municipalities burned?
The fire entered 2 municipalities: Imperia (118 ha, 2.6 %); Pontedassio (38 ha, 2.8 %).
Did the fire reach a town?
The closest fire to a town centre came within 2.2 km of Pontedassio. 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 25.1 °C, humidity dropped to 50 % and gusts hit 50 km/h. The fire danger index (FWI) reached 1, class Very low.
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.
