A new 4.1R magnitude earthquake has hit southwest of the Greek Island of Zakynthos, according to a preliminary reading by the US Geological Survey.
There has been no immediate reports of injuries or damage.
The tremor struck at 13:00 am local time on April 18th, with the epicenter located 20 km northeast from Zante Island on the Ionain 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..
