Magnitude 5.1 earthquake shakes Alaska, British Columbia

A Magnitude 5.1 earthquake shook US state Alaska about 135 miles (217 kilometres) northwest of its capital city Juneau.

Coincidentally, the City and Borough of Juneau's Disaster Preparedness Expo was winding down as the earthquake hit Saturday afternoon. No damage was immediately reported.

The National Weather Service stated there was no tsunami threat from the earthquake, reports AP.

The quake was centered in the narrow sliver of British Columbia, which separates Southeast Alaska and the Yukon. It shook near the Eastern Denali Fault - the same area that experienced a series of larger earthquakes earlier this year.

That string of earthquakes topped out with a magnitude 6.3, which was 10 times stronger than the one felt on Saturday.
