(CNN) -- A 6.7-magnitude earthquake hit near the Greek island of Crete on Wednesday, the U.S. Geological Survey said.
It struck at 12:30 p.m. (5:30 a.m. ET), the USGS said. It was centered about 80 miles (130 kilometers) off the city of Iraklion on Crete, the USGS said.
An earthquake with a 6.7 magnitude is capable of causing significant damage, especially in areas of poor construction.
There were no immediate reports of damage or injuries.
A staff member at Iraklion Airport told CNN they didn't feel the earthquake. Similar reports came from staff members at hotels just outside Iraklion and in western Crete.
A spokesman at the Greek Ministry of Health in Athens, 450 kilometers (280 miles) from the epicenter, also said he didn't feel the quake.
David Booth, a seismologist at the British Geological Survey, explained that the earthquake happened deep below the sea, leading to little risk of tsunami and reducing the likelihood that people would feel tremors.
