Corinth fire, August 2021 Δήμος Κορινθίων · Corinth
The fire started on 14 August 2021 in Corinth, Greece, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 106 hectares from satellite imagery, spread across a single municipality.
It is the 38th largest in Peloponnese since 2016 (of 39 with a page). Number 43 in Greece in 2021, of 45.
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.

106 ha0.2 %
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 12 August 2021 the air beside the fire reached 23 µg/m³ of PM2.5. That day averaged 15: 1.0 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 Corinth fire last?
- Copernicus dates it between 14 August 2021 and 14 August 2021: 1 day between the first and last image with fire.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 106 hectares (1.1 km²). Official national figures may differ.
- Which municipalities burned?
- The fire only entered Corinth (106 ha, 0.2 %).
- What was the weather like?
- During the fire the temperature reached 27.9 °C, humidity dropped to 38 % and gusts hit 40 km/h. The fire danger index (FWI) reached 39, class Very high.
- 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.

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.
