Farsala fire, August 2022 δημοτική ενότητα Φαρσάλων · Farsala

Out · last measured on 9 Aug 2022

The fire started on 9 August 2022 in Farsala, Greece, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 232 hectares from satellite imagery, spread across a single municipality.

It is the 11th largest in Thessaly since 2016 (of 18 with a page). Number 15 in Greece in 2022, of 29.

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.

Frequently asked questions

How long did the Farsala fire last?
Copernicus dates it between 9 August 2022 and 9 August 2022: 1 day between the first and last image with fire.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 232 hectares (2.3 km²). Official national figures may differ.
Which municipalities burned?
The fire only entered Farsala (233 ha, 0.3 %).
What was the weather like?
During the fire the temperature reached 31.7 °C, humidity dropped to 12 % and gusts hit 45 km/h. The fire danger index (FWI) reached 49, 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.
