Four earthquakes strike off Canada’s Vancouver Island
- No tsunami warnings were issued
Four earthquakes -measuring from 4.9 to 6.8 magnitude – struck in quick succession off Canada’s west coast, the US Geological Survey said.
The epicentre of the first 6.6 tremor, at 10:39pm (0549 GMT Monday), was located 218km (135 miles) southwest of Port Hardy – a small municipality on the northeastern tip of British Columbia’s Vancouver Island – and 570km northwest of Seattle.
The second stronger quake, measuring 6.8 on the Richter scale, occurred 195km southwest of the Canadian town more than half an hour later, at 11:16pm.
Six minutes later, a third 6.5 magnitude tremor was registered 220km southwest of Port Hardy – before a weaker 4.9 quake was recorded in the same place 14 minutes after that.
There were no initial reports of damage or injuries, and no tsunami warnings were issued.
The region is located near the Cascadia subduction zone, a mammoth fault line that lies offshore, stretching from northern Vancouver Island to Northern California in the United States.
