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.”
