Out · last detection 9 Aug 2025, 12:26 UTC

The fire started on 9 August 2025 in Preveza, Greece, 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 15th largest in Epirus since 2016 (of 19 with a page). Number 36 in Greece in 2025, of 43.

Frequently asked questions

How long did the Preveza fire last?
Copernicus dates it between 9 August 2025 and 9 August 2025: 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 Preveza (125 ha, 0.3 %).
What was the weather like?
During the fire the temperature reached 35.6 °C, humidity dropped to 23 % and gusts hit 23 km/h. The fire danger index (FWI) reached 32, class 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. 7 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.
