Tsunami hits Hawaii after Canada earthquake

Hawaii, Oct 28 (): A tsunami with waves of height between 3-6 feet caused by 7.7 magnitude earthquake off the coast of western Canada has hit the chain of islands of Hawaii on Saturday night, with authorities saying no damage reported so far.

But the Tsunami alert issued earlier prompted the authorities to order at least 100,000 people on the island state to move to higher ground. Emergency sirens alerted the residents in the coastal areas of the island on late Saturday night. At movie theaters, films were halted in mid-screening as announcements were made urging patrons to return to their homes.

The first waves of Tsunami that hit the island’s coast were said to be nearly 2.5 ft (76 cm) in one area. Waves up to three to six feet high were predicted in few areas, as immediate action was recommended to protect the lives.

Geological survey in US said the 7.7 magnitude earthquake hit 125 miles (200km) south-west of the Canadian mining town of Prince Rupert at a depth of 11 miles (18km), said. The quake was felt on the mainland in Prince Rupert, British Columbia, which is across the Hecate Strait from the islands.

Numerous aftershocks, some as strong as magnitude 4.6, followed the initial quake, Canadian officials reported. There were no immediate reports of major damage due to earthquake.

Initially, the Pacific Tsunami Warning Center said it did not expect a threat beyond the immediate area. But later it said: “A tsunami has been generated that could cause damage along the coastline of all islands in the state of Hawaii.”

The tsunami warning was downgraded to an advisory at about 11:30 p.m. PT for the North Coast and Haida Gwaii, as well as the Central Coast including Bella Coola, Bella Bella and Shearwater.

The National Weather Service says there are reports of water quickly receding in bays, including Hilo Bay on the Big Island.
