A 6.6 magnitude earthquake rocked buildings in Anchorage and caused lamp posts and trees to sway, prompting people to run out of offices and seek shelter under office desks.
The U.S. Geological Survey says the earthquake Friday morning was centred about 12 kilometres north of Alaska’s largest city.
The National Weather Service issued a tsunami warning for Cook Inlet, but a tsunami is not expected to affect Washington or British Columbia.
In a statement, the City of Prince Rupert says it is in contact with emergency authorities and is closely monitoring the situation as it unfolds.
The City says it will activate its emergency alerting system if conditions change.
An Associated Press reporter working in downtown Anchorage saw cracks in a 2-storey building after the quake. It was unclear whether there were injuries.
People went back inside buildings after the earthquake but a smaller aftershock a short time later sent them running back into the streets again.
