Thousands of people fled their homes along the California coast on Friday as a tsunami triggered by the massive earthquake in Japan began hitting the US West Coast after rolling through Hawaii.
But the giant wall of water appeared to have lost much of its energy as it roared thousands of miles across the Pacific Ocean toward North America, according to initial reports from officials in the United States, Mexico and Canada.

The tsunami was expected to reach South America's coastline later on Friday.
Tidal surges in the Hawaiian island chain were not much higher than normal, officials there said. There were no reports of injuries or severe inland property damage and the tsunami warning was later downgraded to an advisory.
"The models are showing that the waves are dying down and so hopefully this event will be over in two to five hours," Laura Furgione, a senior official at the US National Oceanic and Atmospheric Administration, told reporters.
Waves crashing ashore along the Californian coast were larger than normal, but only the town of Crescent City, near the California border with Oregon, and Santa Cruz, 72 miles (115 km) south of San Francisco, appeared to suffer any real damage.
About 35 boats and most of the harbor docks were damaged in Crescent City, where waves were more than 6 feet (2 metres), while Santa Cruz sustained about $2 million in damages to docks and vessels, emergency management officials said. Four people in Crescent City were swept out to sea but later rescued, officials said.
Thousands of residents were evacuated along the California coast, including 6,000 near Santa Cruz, said Jordan Scott, spokesman for the California Emergency Management Agency.
No injuries or property damage were reported after a series of four tsunami waves hit the Hawaiian island of Oahu, said John Cummings, a spokesman for emergency management in Honolulu. The tsunami warning for Hawaii was later downgraded to an advisory.
South America prepares for tsunami arrival
Ecuador took extreme precautions after President Rafael Correa declared a state of emergency across the Andean nation on national television and urged residents to move inland.
The area at risk includes the Galapagos Islands -- a popular tourist destination known for its wildlife, including endangered species, that inspired British naturalist Charles Darwin's evolution theory in the 19th century.
On Easter Island, a Chilean territory in the South Pacific, authorities planned to move residents to higher ground, in preparation for a possible tsunami on Friday afternoon.
Chilean President Sebastian Pinera, whose country was hit by an 8.8 magnitude quake and ensuing tsunamis that killed more than 500 people a year ago, told Chileans to remain alert.
Peruvian officials said they were waiting until late afternoon to decide if they would order evacuations from low-lying coastal areas such as the port city of Callao.
Many ports along Mexico's western coast were closed, including Los Cabos and Salina Cruz in southern Oaxaca, the only oil-exporting terminal on the country's Pacific side.
Mexican officials said high waves had hit the northwestern Pacific coast but there were no reports of damage.
Authorities in the Canadian province of British Columbia advised residents to evacuate marinas, beaches and other low-lying areas, but officials there said the waves were minimal.
