The United States Geological Survey recorded a Magnitude 6.1 Earthquake at a depth of 10.0 km, about 10 km to the southwest of the municipality of Bigadiç in Balıkesir Province, Turkey, slightly before 7.55 pm local time (slightly before 4.55 pm GMT) on Sunday 10 August 2025. Sixteen buildings are reported to have collapsed following the event, although the majority are reported to have been derelict before the event, with at least one fatality, an 81-year-old woman who died after being rescued from the remains of a collapsed building, with 29 more people having been injured.
Balıkesir Province lies close to the boundary between the Anatolian Plate, to the north, the Aegean Sea Plate (underlying the Peloponnese, Attica, The Cyclades Islands, Crete, the Dodecanese Islands and Turkey to the southeast of the Taurus Mountains) to the west and the African Plate to the south. Northern Greece and the north coast of Turkey lie on the Eurasian Plate. Both countries are highly prone to earthquakes because of this.
To the east the Arabian Plate is being pushed north and west by the movement of the African Plate, further to the south. This leads to a zone of tectonic activity within the province, as the Arabian and Anatolian plates are pushed together, along the East Anatolian Fault, and past one-another, along the Dead Sea Transform.
This movement also leads to a zone of faulting along the northern part of Turkey, the North Anatolian Fault Zone, as the Anatolian Plate is pushed past the Eurasian Plate, which underlies the Black Sea and Crimean Peninsula (transform faulting). This is not a simple process, as the two plates constantly stick together, then break apart as the pressure builds up, leading to Earthquakes, which can be some distance from the actual fault zone.
