Rafina-Pikermi fire, July 2022 Ραφήνα-Πικέρμι · Penteli, Pallini, Rafina-Pikermi
Out · last detection 20 Jul 2022, 01:27 UTC
The fire started on 19 July 2022 in Rafina-Pikermi, Greece, and satellites saw it burning for 2 days. Copernicus mapped a burnt perimeter of 2,836 hectares from satellite imagery, spread across 4 municipalities.
It is the 12th largest in Attica since 2016 (of 32 with a page). Number 2 in Greece in 2022, of 29.

It was 6.3 times larger than the median of its twins and lasted 2 days, against 1 day.
Only 3 of its 16 twins burned more. The weather on the first day does not explain everything: the wind in the following days, the fuel and the firefighting also count. In 11 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 1.9 mm.

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 Rafina-Pikermi fire last?
- Copernicus dates it between 19 July 2022 and 20 July 2022: 2 days between the first and last image with fire.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 2,836 hectares (28.4 km²). Official national figures may differ.
- Which municipalities burned?
- The fire entered 4 municipalities: Penteli (1,142 ha, 33 %); Pallini (841 ha, 28 %); Rafina-Pikermi (832 ha, 20 %); Dionysos (26 ha, 0.4 %).
- What was the weather like?
- During the fire the temperature reached 27.4 °C, humidity dropped to 32 % and gusts hit 73 km/h. The fire danger index (FWI) reached 70, class Extreme.
- 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.
- 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 1 day and their median area 448 ha; 25 % went past 1,000 ha. Only 3 of its 16 twins burned more. The weather on the first day does not explain everything: the wind in the following days, the fuel and the firefighting also count. In 11 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 1.9 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.
Report an error
How we know this
- Perimeter: EFFIS (Copernicus), mapped on satellite imagery.
- Dates from the perimeter: the VIIRS detections inside it did not change them. 112 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 2020, 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.
