A tsunami warning has been issued for Hawaii after a 7.7-magnitude earthquake rocked an island off the west coast of Canada Saturday.
The Pacific Tsunami Warning Center originally said there was no threat to the islands, but a warning was issued later Saturday and remains in effect until 7 p.m. Sunday. A small craft advisory is in effect until Sunday morning.
A small tsunami prompted state and federal officials to warn people in southeast Alaska and down the Canadian coast to take precautions.
The temblor shook the Charlotte Islands area on Saturday night, followed by a 5.8-magnitude aftershock several minutes later.
The center says the first tsunami wave could hit the islands by about 10:30 p.m. local time (1:30 a.m. PDT Sunday).
