Seferihisar fire, October 2017 Seferihisar
The fire started on 17 October 2017 in Seferihisar, Türkiye, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 125 hectares from satellite imagery, spread across a single municipality.
It is the 54th largest in İzmir since 2016 (of 68 with a page). Number 82 in Türkiye in 2017, of 98.

Where it burned
How it evolved, day by day
Fire radiative power detected each day, in megawatts, and number of hotspots. The magenta bar marks the peak day.
The weather it burned in
It had gone 8 days without rain (1 mm or more) when it started. Rain came after the fire: 15.1 mm on 24 Oct.
This area had burned before
No earlier perimeters overlap this fire since 2016, when the satellite record begins.
What happened to each town
-
125 ha reached on 17 Oct0.3 %
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.
What burned
- Other natural land100 %
Land cover inside the perimeter according to Corine Land Cover, as reported by Copernicus.
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 20 October 2017 the air beside the fire reached 33 µg/m³ of PM2.5. That day averaged 25: 1.7 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 Seferihisar fire last?
- Copernicus dates it between 17 October 2017 and 17 October 2017: 1 day between the first and last image with fire.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 125 hectares (1.2 km²). Official national figures may differ.
- Which municipalities burned?
- The fire only entered Seferihisar (125 ha, 0.3 %).
- Did the fire reach a town?
- The closest fire to a town centre came within 3.9 km of Seferihisar. 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 24.2 °C, humidity dropped to 44 % and gusts hit 45 km/h. The fire danger index (FWI) reached 31, class High.
- Where does this data come from?
- From the EFFIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Türkiye (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.
Emergency number: 112

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 ADM2 (Open Data Commons Open Database License 1.0). 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.
