''A powerful earthquake shook a large swath of Alaska on Thursday morning, knocking things off shelves and causing people to take cover but bringing no immediate reports of major damages.
The quake had a preliminary magnitude of 6.2, and hit at 9:51 a.m local time. The epicentre was about 129 kilometres northwest of the state's largest city, where it was strongly felt and lingered for at least one minute, the Alaska Earthquake Center said.''
