A tsunami warning and advisory have been canceled for Hawaii after a 7.7-magnitude earthquake that struck off the west coast of Canada Saturday night local time sent small tsunamis to southeast Alaska, coastal British Columbia and off Haida Gwaii, formerly called the Queen Charlotte Islands.

The National Weather Service had initially issued a tsunami warning to these areas, though later canceled it for coastal areas of British Columbia and southern Alaska, while downgrading the warning to an advisory for Hawaii. The advisory was canceled Sunday morning Eastern Time.
