The strongest, measured at 4.8-magnitude, was recorded near the hardest-hit town of Karaburun — about 100 kilometers west of the city of Izmir.
The powerful aftershocks caused panic as buildings again swayed in the region.
The tremors were felt in the nearby provinces, including Aydın, Uşak, Manisa, Muğla, and Balıkesir, according to local sources said.
There were no immediate reports of damage or casualties. (ILKHA)
