The quake struck Izmir's Karaburun district at 3.28 p.m. local time (1228 GMT) at a depth of 22.98 kilometers (14 miles), the authority said.
AFAD Izmir Director Osman Metin Saroglu said no causalities have been reported so far.
Dr. Suha Ozden, vice rector at Canakkale Onsekiz Mart University and Faculty of Engineering Geology Department professor, warned about quake aftershocks.
"As it is the nature of every earthquake, we can experience aftershocks that can range between 4.9 and 5.2 magnitude in the upcoming days," Ozden said.
"The earthquake we experienced today was a principal earthquake. The aftereffects will definitely not be over 6.2 magnitude," he added.
In late May, an earthquake measuring 5.1 magnitude hit western Manisa province; no causalities were reported in that incident.
Greece was also reportedly affected by an earthquake that struck between the Greek islands of Lesbos and Chios on Monday afternoon.
According to the Greek Civil Protection, there were no casualties.
However, landslides in southern part of Lesbos ended up blocking some roads while some old buildings in villages had also been damaged.
