Warning sirens have sounded across the Hawaiian islands after a 7.7 magnitude earthquake that struck in the Queen Charlotte Islands region off the west coast of Canada triggered a tsunami that is heading towards Hawaii.
The Pacific Tsunami Warning Centre says the first tsunami wave is expected to arrive in the Pacific island state at 10.28pm (7.28pm AEDT tonight).
Residents have been advised to evacuate coastal areas and warning sirens have sounded across the Hawaiian islands.
Centre officials have told CNN waves of one to two metres are expected.
The centre says the tsunami waves could wrap around the islands so all shores are at risk and the tsunami could consist of multiple waves.
The warning was issued after a magnitude 7.7 earthquake struck off the Queen Charlotte Islands late Saturday.
