Praia a Mare fire, August 2025 Aieta, Praia a Mare
Out · last detection 16 Aug 2025, 00:33 UTC
The fire started on 15 August 2025 in Praia a Mare, Italy, and satellites saw it burning for 5 days. Copernicus mapped a burnt perimeter of 135 hectares from satellite imagery, spread across 2 municipalities.
It is the 94th largest in Cosenza since 2016 (of 145 with a page). Number 152 in Italy in 2025, of 216.
The power measured by the satellite is low (1.5 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

This area had burned before
56% of the perimeter overlaps earlier fires recorded since 2016: 72 ha in 2017, 25 ha in 2023. Part of it burned more than once, so the yearly figures add up to more than the 75 ha that had burned before.

Inside the perimeter there was no noticeable built-up land and almost nobody lived there (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.

How a twin is chosen
- Same area: fires that have already ended, less than 250 km from this one, since 2016.
- Same start: we compare the FWI on the first day, the minimum humidity that day and the run of days without rain before it. The slider sets how much they may differ.
- Only pages with final weather data (ERA5 reanalysis) calculated in the same way as this fire’s; agricultural and grass burns and pages with data under review are left out.
- Fires burning at the same time as this one (a week before or after) are left out: they share the same spell of weather and do not count as a precedent.
- They are sorted by similarity, and the outlines of the first five are drawn.

Frequently asked questions
- How long did the Praia a Mare fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 15 August 2025 to 19 August 2025 (5 days). The perimeter dates it from 15 August 2025 to 16 August 2025.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 135 hectares (1.4 km²). Official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Aieta (69 ha, 1.4 %); Praia a Mare (65 ha, 2.8 %).
- Did the fire reach a town?
- The fire started in Praia a Mare and reached its centre: the point marking it was inside the burnt area or less than 500 metres from it. That does not mean houses burned.
- What was the weather like?
- During the fire the temperature reached 29.4 °C, humidity dropped to 45 % and gusts hit 36 km/h. The fire danger index (FWI) reached 11, class Low.
- Where does this data come from?
- From the EFFIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Italy (geoBoundaries). It is not an official report.
- How did the fires that started in similar weather in this area end?
- Fires less than 250 km away that started since 2016 with a similar FWI, humidity and dry spell: 16. Their median duration was 2 days and their median area 122 ha; 0 % went past 1,000 ha. In 3 of 16, not even 1 mm fell in the ten days after the end: they went out without rain. In the rest, the first rainy day brought a median of 1.4 mm.
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 adjusted with the VIIRS detections inside the perimeter, which said 15 August 2025 to 16 August 2025. 3 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 ADM4 (Creative Commons Attribution 3.0 License). 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.
