WASHINGTON, Oct 22, 2018 (BSS/AFP) – Four earthquakes — measuring from 4.9
to 6.8 magnitude — struck in quick succession off Canada’s west coast late
Sunday, the US Geological Survey said.
The epicenter of the first 6.6 tremor, at 10:39pm (0549 GMT Monday), was
located 135 miles (218 kilometers) southwest of Port Hardy — a small
municipality on the northeastern tip of British Columbia’s Vancouver Island –
– and 355 miles northwest of Seattle.
The second stronger quake, measuring 6.8 on the Richter scale, occurred 122
miles 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 138 miles
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.
