A new 4.5R magnitude earthquake has hit southeast of the Greek Island of Zakynthos, according to a preliminary reading by the US Geological Survey.
There have been no immediate reports of injuries or damage.
The tremor struck at 01:43 am local time on October 12th, with the epicenter located 12 km southeast from Zante Island on the Ionian Sea.
There are no reported casualties but the quake was strong enough to worry locals in Zakynthos and the neighboring Greek islands.
Earthquakes have historically caused widespread damage across central and southern Greece, Cyprus, Sicily, and other neighboring regions.
Last year a series of strong earthquakes on the island of Kefalonia damaged hundreds of homes and injured more than a dozen people.
