The Athens Geodynamic Institute says an earthquake with a preliminary magnitude of 5 has hit western Greece. Authorities say there have been no reports of damage or injuries, according to Otago Daily Times.

The quake struck at 8:02 a.m. (1702 NZT) on Wednesday with an epicenter beneath the seabed southeast of the Ionian island of Kefalonia and 300km west of the capital, Athens.

The US Geological Survey is giving a preliminary magnitude of 4.7 for the earthquake. The European Mediterranean Seismological Center gave a magnitude of 5. Measurements of the severity of a quake by different institutes often vary in the initial hours and days.

Greece is one of the world`s most seismologically active countries, but most quakes are relatively small and do not cause injuries.
