A powerful quake of magnitude 6.8 struck off the eastern coast of Greenland on Friday, the US Geological Survey said.
The quake, initially reported as a magnitude 7.1, struck at 0149 GMT. Its epicenter was in a remote area 253 miles (407 km) east of Ittoqqortoormiit in Greenland.
It was strong enough to cause local waves in the Greenland Sea but was not expected to cause a tsunami in more populated areas, the US Tsunami Warning System said.
