Terzigno fire, July 2016 Terzigno
The fire started on 20 July 2016 in Terzigno, Italy, and satellites saw it burning for 3 days. Copernicus mapped a burnt perimeter of 243 hectares from satellite imagery, spread across a single municipality.
It is the 4th largest in Napoli since 2016 (of 12 with a page). Number 34 in Italy in 2016, of 78.

The weather it burned in
It had gone 4 days without rain (1 mm or more) when it started. Rain came after the fire: 3.8 mm on 25 Jul.

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.

The smoke
CAMS · CopernicusOn 20 July 2016 the air beside the fire reached 30 µg/m³ of PM2.5. That day averaged 22: 1.5 times the WHO daily guideline (15).
Particles from the Copernicus CAMS model at the centre of the perimeter; these are not measurements in each town. The pale bar is the worst hour, the solid one the daily average.

Frequently asked questions
- How long did the Terzigno fire last?
- Copernicus dates it between 20 July 2016 and 22 July 2016: 3 days between the first and last image with fire.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 243 hectares (2.4 km²). Official national figures may differ.
- Which municipalities burned?
- The fire only entered Terzigno (243 ha, 10 %).
- Did the fire reach a town?
- The closest fire to a town centre came within 3.5 km of Terzigno. 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 26.8 °C, humidity dropped to 45 % and gusts hit 36 km/h. The fire danger index (FWI) reached 17, class Moderate.
- 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.
