A powerful earthquake has hit Canada’s Pacific coast province of British Columbia.
The US Geological Survey reported its magnitude as 7.7 and at a depth of 10 km. There have been no immediate reports of damage.
The quake was centred 198 km south-west of the port city of Prince Rupert.
The Pacific Tsunami Center issued a tsunami alert for Hawaii before downgrading it, but only after 100,000 people had sought higher ground, and Alaska issued a warning for some coastal sectors.
