Erymanthos fire, June 2024 Ερυμάνθου · West Achaea, Erymanthos, Ilida
The fire started on 21 June 2024 in Erymanthos, Greece, and satellites saw it burning for 2 days. Copernicus mapped a burnt perimeter of 4,336 hectares from satellite imagery, spread across 3 municipalities.
It is the 2th largest in Western Greece since 2016 (of 36 with a page). Number 3 in Greece in 2024, of 42.

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.

Land cover inside the perimeter according to Corine Land Cover, as reported by Copernicus.
People and buildings inside the perimeter
GHSL 2025Inside the perimeter there were about 12 hectares of built-up land and about 500 residents (GHSL 2025, satellite-based estimate).
This is an estimate on 100 m cells, made from satellite imagery and census data: it does not mean that homes burned or that anyone was harmed. The perimeter also contains land that never burned. The GHSL 2025 epoch is a projection made from 2020 and earlier data.

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 23 June 2024 the air beside the fire reached 27 µg/m³ of PM2.5. That day averaged 17: 1.1 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Erymanthos fire last?
- Copernicus dates it between 21 June 2024 and 22 June 2024: 2 days between the first and last image with fire.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 4,336 hectares (43.4 km²). Official national figures may differ.
- Which municipalities burned?
- The fire entered 3 municipalities: West Achaea (2,359 ha, 3.5 %); Erymanthos (1,877 ha, 2.8 %); Ilida (102 ha, 0.2 %).
- What was the weather like?
- During the fire the temperature reached 37.7 °C, humidity dropped to 21 % and gusts hit 47 km/h. The fire danger index (FWI) reached 46, 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.

How we know this
- Perimeter: EFFIS (Copernicus), mapped on satellite imagery.
- Dates from the perimeter: the VIIRS detections inside it did not change them. 47 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.
- Built-up area and population come from the JRC Global Human Settlement Layer (epoch 2025, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.
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.
