Develi fire, 11 October 2020 Develi
The fire started on 11 October 2020 in Develi, Türkiye, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 163 hectares from satellite imagery, spread across a single municipality.
It is the 17th largest in Kayseri since 2016 (of 24 with a page). Number 139 in Türkiye in 2020, of 212.

The weather it burned in
It had gone 15 days without rain (1 mm or more) when it started. Rain came after the fire: 1.0 mm on 21 Oct.
This area had burned before
21% of the perimeter overlaps earlier fires recorded since 2016: 34 ha in 2017.
What happened to each town
-
164 ha reached on 11 Oct0.1 %
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.
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 13 October 2020 the air beside the fire reached 32 µg/m³ of PM2.5. That day averaged 27: 1.8 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Develi fire last?
- Copernicus dates it between 11 October 2020 and 11 October 2020: 1 day between the first and last image with fire.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 163 hectares (1.6 km²). Official national figures may differ.
- Which municipalities burned?
- The fire only entered Develi (164 ha, 0.1 %).
- Did the fire reach a town?
- The fire started in Develi and came within 17.7 km of its centre. That is the distance from the perimeter, or the nearest hotspot, to the point marking the centre; it does not mean it entered the houses.
- What was the weather like?
- During the fire the temperature reached 27.4 °C, humidity dropped to 22 % and gusts hit 28 km/h. The fire danger index (FWI) reached 35, 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.

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 from the perimeter: the VIIRS detections inside it did not change them. 6 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 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.
