Earthquake jolts North Sea off Denmark

An earthquake that measured 4.7 on the Richter scale late Friday jolted the eastern North Sea off north-western Denmark but there were no reports of injuries or damage, police and geologists said Saturday, DPA reported.

The earthquake struck some 140 kilometres west of the city of Aalborg at a depth of 10 kilometres, the European-Mediterranean Seismological Centre said.

Stig Asbjorn Schack Pedersen, researcher at the Geological Survey of Denmark and Greenland, said the quake was relatively strong for the Scandinavian country.

"The earthquakes we have in Denmark are usually between magnitude 2.5 and 3," Schack Pedersen told the Jyllands-Posten daily.
