Saronikos fire, July 2017 Σαρωνικού Αττικής · Saronikos
The fire started on 31 July 2017 in Saronikos, Greece, and satellites saw it burning for 2 days. Copernicus mapped a burnt perimeter of 473 hectares from satellite imagery, spread across a single municipality.
It is the 17th largest in Attica since 2016 (of 32 with a page). Number 11 in Greece in 2017, of 32.

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.

What happened to each town
-
474 ha4.0 %
Burnt area inside each municipality, from crossing the official perimeter with administrative boundaries. The distance runs from the point marking the centre of each area to the nearest fire: staying a kilometre away does not mean it reached the houses.

The weather day by day
ECMWF ERA5 reanalysis at the fire location, the standard reference for past weather, and the Canadian Fire Weather Index (the same system Copernicus uses), computed by WorldFires from that data. Days after the fire run until the first rain.

The smoke
CAMS · CopernicusOn 3 August 2017 the air beside the fire reached 15 µg/m³ of PM2.5, but no daily average passed the WHO guideline (15).

Frequently asked questions
- How long did the Saronikos fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 31 July 2017 to 1 August 2017 (2 days). The perimeter dates it from 31 July 2017 to 31 July 2017.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 473 hectares (4.7 km²). Official national figures may differ.
- Which municipalities burned?
- The fire only entered Saronikos (474 ha, 4.0 %).
- What was the weather like?
- During the fire the temperature reached 31.1 °C, humidity dropped to 31 % and gusts hit 70 km/h. The fire danger index (FWI) reached 51, class Extreme.
- Where does this data come from?
- From the EFFIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Greece (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.

How we know this
- Perimeter: EFFIS (Copernicus), mapped on satellite imagery.
- Dates adjusted with the VIIRS detections inside the perimeter, which said 31 July 2017 to 31 July 2017. No Suomi-NPP VIIRS detections on those dates.
- We have not matched this page with any official record.
- Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.
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 ADM3 (CC0 1.0 Universal (CC0 1.0) Public Domain Dedication). 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.
