A strong seabed earthquake with a preliminary magnitude of 5.7 jolted the Ionian Sea island of Zankynthos early Tuesday, causing no injuries or damage, authorities said.
The undersea quake occurred at 3:02 a.m. (0002 GMT) and had its epicenter on the seabed south of the island, the Athens Geodynamic Institute said.
It was the third quake with an epicenter in the same area in the past week. Another 5.7 jolted the same area on April 5 and a 4.8 on April 3.
The region is one of the most earthquake-prone in Greece, which is considered one of the most seismically active countries in the world, reports the AP.
