The tsunami indeed reached Hawaii but its strength was quite insignificant as the waves which his the coasts of the US islands did not exceed 0.7 m (2.5 feet) above the regular sea level.
Therefore the tsunami alert was lifted on Sunday around 11:00 GMT as the seismic waves were lower than originally anticipated. Initially the authorities announced that waves between 3 to 6 feet are expected to storm the shoreline.
Canadian authorities released on Saturday evening, a tsunami alert after a “major 7.7 magnitude earthquake” occurred off Canada’s western coast.
“The alert is in effect for coastal areas from British Columbia to Alaska and from northern Vancouver Island to Cap Decision in Alaska (137 miles southeast of Sitka),” the Canadian Minister of Natural Resources said in a statement, asking residents in targeted areas to follow the instructions of local authorities on a possible evacuation to high land.
The quake struck Saturday evening local time (Sunday morning at 03.04 GMT) in the region of Haida Gwaii archipelago (formerly the Queen Charlotte Islands). It was felt in northern British Columbia, including Prince Rupert, Quesnel and Houston, added the minister who revealed that no casualties or damages were reported.
According to the American Institute of Geophysics USGS, the epicenter was located 139 kilometers south of Masset.
Haida Gwaii Islands are an archipelago formed of about 150 islands located off the coast of British Columbia and are home to approximately 5,000 people.

Update 2:15 p.m. – the tsunami warning issued Saturday night to Sunday morning in Hawaii (United States) following a powerful earthquake offshore the west coasts of Canada, was lifted at 11.00 GMT.
“According to all available data, the tsunami threat was reduced (…) and should not grow,” reads a statement from the tsunami alert center in the Pacific.
Update 9:45 a.m. – the seismic waves triggered by the 7.7 magnitude earthquake, hit Hawaii, but the water level was just half a meter above normal.
Most areas in Hawaii were already hit by the fourth seismic waves, said Gerard Fryer of the Pacific Tsunami Warning Center. According to Fryer, the data show that evacuation was not necessary, but it was still a good precaution measure.
The highest wave was 58 centimeters, but in general the waves are smaller than expected.
Update 8:10 a.m. – At least three seismic waves hit the coast of the Canadian province of British Columbia, after a 7.7-magnitude tremor which jolted Canada’s Haida Gwaii island, CBC News television channel reported on its website.
The waves did not cause damage, but many people were evacuated in Haida Gwaii and Port Edward, near Prince Rupert. Officials could provide information on the total number of those evacuated.
Kelly Kryzanowski of the Management Center for Emergency Situations of British Columbia said the evacuation center was installed in Haida Gwaii.
“It is reported that some areas experienced power breakdowns and telephone network issues. We have no information on the occurrence of damage,” said Kryzanowski.
