AP- One of the strongest earthquakes ever recorded struck off Russia’s sparsely populated Far East early Wednesday, sending tsunami waves into Japan, Hawaii and the U.S. West Coast. Several people were injured, but none gravely, and no major damage has been reported so far.
Authorities warned the risk from the 8.8 magnitude quake could last for hours, and millions of people potentially in the path of the waves were initially told to move away from the shore or seek high ground.
But the danger already appeared to be lessening in some places, with authorities downgrading their warnings in Hawaii, Japan and parts of Russia.
Residents fled inland as ports flooded on Kamchatka near the quake’s epicenter, while frothy, white waves washed up on the shore in northern Japan. Cars jammed streets and highways in Honolulu, with standstill traffic even in areas away from the sea.
People flocked to evacuation centers in affected areas of Japan, with memories fresh of the 2011 earthquake and tsunami that caused reactor meltdowns at a nuclear power plant. No abnormalities in operations at Japan’s nuclear plants were reported Wednesday.
Russian authorities said several people were injured, but said all were in stable condition, though they gave few details. In Japan, at least one person was injured.
A tsunami height of 3 to 4 meters (10 to 13 feet) was recorded in Kamchatka, 60 centimeters (2 feet) on Japan’s northern island of Hokkaido, while tsunami waves about 2 to 5 feet high reached San Francisco early Wednesday, officials said.
Much of the West Coast, spanning California, Oregon, Washington state, Briefly coastal Alaska and the Canadian province of British Columbia, were under a tsunami advisory.
Hawaii downgrades to tsunami advisory
Hawaii was still under a tsunami advisory as Wednesday began, but evacuation orders on the Big Island and Oahu, the most populated island, had been lifted.
An advisory means there is the potential for strong currents and dangerous waves, as well as flooding on beaches or in harbors.
“As you return home, still stay off the beach and stay out of the water,” said James Barros, administrator of the Hawaii Emergency Management Agency.
The impact of the tsunami could last for hours or perhaps more than a day, said Dave Snider, tsunami warning coordinator with the National Tsunami Warning Center in Alaska.
“A tsunami is not just one wave,” he said. “It’s a series of powerful waves over a long period of time. Tsunamis cross the ocean at hundreds of miles an hour — as fast as a jet airplane — in deep water. But when they get close to the shore, they slow down and start to pile up. And that’s where that inundation problem becomes a little bit more possible there.”
Hawaii Gov. Josh Green earlier said Black Hawk helicopters were activated and high-water vehicles ready to go in case authorities needed to rescue people.
The Oregon Department of Emergency Management said on Facebook that small tsunami waves were expected along the coast. It urged people to stay away from beaches, harbors and marinas and to remain in a safe location away from the coast until the advisory is lifted.
“This is not a major tsunami, but dangerous currents and strong waves may pose a risk to those near the water,” the department said.
A tsunami of less than 30 centimeters (under 1 foot) was forecast to hit parts of Vancouver Island, British Columbia, and waves of up to 1.4 feet (under 30 centimeters) above tide levels were observed in Alaska’s Aleutian Islands.
