ATHENS - Greek authorities say an earthquake with preliminary magnitude of 5.1 has struck the north of the country. No injuries or damage were immediately reported.
The Athens Geodynamic Institute says the undersea earthquake occurred at 3:34 a.m. Tuesday 151 miles (243 kilometres) north of the Greek capital, Athens, off the coast of the northern peninsula of the Athos monastic community. The United States Geological Survey gave the preliminary magnitude as 5.3. It is common for magnitudes given by different seismological centres to vary.
Greece is in one of the world's seismically active areas, with hundreds of quakes occurring each year. The vast majority cause no injuries.
