A magnitude 3.4 earthquake was recorded in the Simav district of Kütahya province, western Turkey, at 09:12 local time on Saturday, October 17, 2026, according to AFAD, the country's Disaster and Emergency Management Presidency. The agency placed the epicenter at coordinates 39.23617°N, 29.02783°E, with a depth of 6.79 kilometers.
AFAD said in its announcement that no negative effects or structural damage had been reported following the tremor, and that emergency teams were continuing field assessments in the area at the time the data was published.
A Cluster of Small Tremors Around Simav
The 3.4-magnitude quake was not an isolated event. AFAD data cited by Habertürk showed a smaller tremor of magnitude 2.2 at a depth of 7.69 kilometers striking the same area roughly one minute earlier, at 09:11:48 local time.
Several other minor earthquakes were recorded elsewhere in western and central Turkey the same morning, including tremors of magnitude 2.3 near Çeşme in İzmir province, magnitude 2.2 near Honaz in Denizli province, and magnitude 2.2 near Fethiye in Muğla province, Habertürk reported.
Why Simav Is Seismically Active
Simav lies on the Simav fault, which the English-language Wikipedia entry on the 2011 Kütahya earthquake describes as an active fault that has previously generated earthquakes of similar intensity in the region.
The district has a history of larger, damaging earthquakes. On May 19, 2011, a magnitude 5.8 earthquake centered near Simav killed 2 people and injured 122, according to the English-language Wikipedia summary of that event, which states the quake was followed by more than 450 aftershocks, the strongest reaching magnitude 4.6 about ten minutes after the main shock, with eight aftershocks measuring 4.0 or greater.
