A 5.5 magnitude earthquake has hit northeast of the island of Crete, Greece, according to a preliminary reading by the US Geological Survey. The tremor struck at 1:34 am local time on Saturday, with the epicenter located 83 miles (133 km) ENE of Iraklion, Crete, Greece. There are no reported casualties but the quake was strong enough to worry locals in Crete 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.
