On 10 August 2025 at 19:53 TRT, a Mww 6.1 earthquake struck the Sındırgı district of Balıkesir, Turkey, 10 km (6.2 mi) south-southwest of Bigadiç.[1] One person died and 52 others were injured.
Tectonic setting
[edit]The western part of Anatolia forms part of the zone of active extensional tectonics that extends westwards through the Aegean Sea plate to the Gulf of Corinth. This extension is a result of the rollback of the African plate as it subducts beneath the Aegean Sea plate. Previous earthquakes in this area include a sequence of three destructive events during the 1969–1970 period, the 1969 Demirci earthquake, the 1969 Alaşehir earthquake and the 1970 Gediz earthquake.[2][3]
Earthquake
[edit]The United States Geological Survey (USGS) reported a magnitude of Mww 6.1. Its epicenter was located 10 km (6.2 mi) south-southwest of Bigadiç in Balıkesir Province.[1] The Kandilli Observatory said that the quake was centered near the districts of Alakır and Sındırgı, and occurred at a depth of 7.7 km (4.8 mi).[4] The earthquake's epicenter lies close to the western end of the Simav fault zone, which is interpreted to be responsible for the 1969 Demirci event.[5]
The earthquake had a maximum Modified Mercalli intensity of IX (Violent),[1] and was felt as far away as Istanbul, İzmir, Aydın, Eskişehir, and Tekirdağ.[6] By 12 August at 9:00 local time, 786 aftershocks were recorded of which 17 exceeded magnitude 4.0,[7] and included a mb 4.2 event at 17:15 UTC.[8]
The earthquake mainshock was preceded by a sequence of foreshocks, with three events of magnitude >3 during the previous three days.[5]
Impact
[edit]Two minarets were damaged or destroyed in Sındırgı.[9] A three-story apartment block collapsed, 193 buildings were severely damaged[10] and 61 were slightly damaged.[11] An 82-year-old man died after he was rescued from a collapsed building[12] and 52 people were initially hospitalized due to injuries or panic.[13][14] Eight houses were also damaged in Manisa. Most of the buildings that collapsed or suffered damage were uninhabited and abandoned.[15] A sinkhole also appeared in a rural area near Odunpazarı in Eskişehir Province.[16]
Around 1,100 search and rescue personnel and 50 damage assessment teams were deployed to the affected areas.[12] The owner and contractor of the building in Sındırgı in which the fatality was recorded was taken into custody on suspicion of "causing death and injury by negligence".[17]
