B.C. coast struck by mag. 6.4 aftershock following powerful 7.7 earthquake

VANCOUVER—The second largest earthquake in Canadian history was still rattling nerves Sunday, with aftershocks off the northern coast of British Columbia. On Saturday night, a massive 7.7 magnitude earthquake hit about 30 kilometres north of Sandspit, B.C., in the Haida Gwaii islands shortly after 8 p.m. local time, sending tremors north through the island chain and south as far as Metro Vancouver. It was the largest earthquake to be felt in Canada since an 8.1-magnitude quake in the same region back in 1949. 

A surprisingly strong 6.4-magnitude aftershock in the same area shook residents again Sunday afternoon around 2 p.m. Earthquake expert Brent Ward from Simon Fraser University said he expects aftershocks for days ahead, but generally in the 4- to 5-magnitude range.“We don’t really understand how to predict earthquakes enough to know if something like this could be an indicator of a larger earthquake in the same vicinity occurring in the future,” Ward said Sunday. “If we get another earthquake that’s greater than 7.7, it wouldn’t be an aftershock, it would be a new earthquake.”
