VANCOUVER – A tsunami warning has been downgraded for British Columbia’s north-central coast after a powerful 7.7 earthquake shook the region.

Residents in several areas of B.C.’s North Coast and Haida Gwaii were evacuated after the quake rumbled through shortly after 8 p.m. Saturday.

An official with the Institute of Ocean Science says the largest wave caused by the quake hit Langara Island, a northern Haida Gwaii island, and measured just under 70 centimetres.

Officials say tsunami advisories still remain up for those areas and the northern and southern ends of Vancouver Island, meaning there’s still a possibility of a low-level tsunami.

Residents along the northern coast say the violent and rolling earthquake struck and was felt from Alaska to Metro Vancouver.

B.C. Justice Minister Shirley Bond says officials are grateful that there appears to be little damage from the quake.
