Earthquake causes tsunami in Russia and Japan

TOKYO — One of the world's strongest earthquakes struck Russia's Far East early Wednesday, an 8.8-magnitude tremor that triggered a tsunami in the northern Pacific region and prompted warnings for Alaska, Hawaii and other coasts southward toward New Zealand.

Tsunami warning sirens blared Tuesday in Honolulu and people moved to higher ground.

The Japan Meteorological Agency said a tsunami measuring 40 centimeters (1.3 feet) was detected in Tokachi, on the southern coast of Hokkaido, the northernmost of the country's main islands.

The Russian areas nearest to the earthquake's epicenter on the Kamchatka Peninsula reported damage and evacuations, but no serious injuries.

The first tsunami wave hit the coastal area of Severo-Kurilsk, the main settlement on Russia's Kuril Islands in the Pacific, according to the local governor Valery Limarenko. He said residents were safe and staying on high ground until the threat of a repeat wave was gone.

The Pacific Tsunami Warning Center said a tsunami had been generated by the quake that could cause damage along the coastlines of all the Hawaiian islands.

"Urgent action should be taken to protect lives and property," the warning stated. The first waves were expected around 7 p.m. Tuesday local time.

The Oregon Department of Emergency Management said on Facebook that small tsunami waves were expected along the coast starting around 11:40 p.m. local time, with wave heights between 1 to 2 feet (30 to 60 centimeters). 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.

Much of the West Coast spanning Canada's British Columbia province, Washington state, and California was also under a tsunami advisory.

The quake at 8:25 a.m. Japan time had a preliminary magnitude of 8.0, Japanese and U.S. seismologists said. The U.S. Geological Survey later updated its measurement to 8.8 magnitude, and the USGS said the quake occurred at a depth of 20.7 kilometers (13 miles).

The quake was centered about 119 kilometers (74 miles) east-southeast from the Russian city of Petropavlovsk-Kamchatsky, which has a population of 180,000, on the Kamchatka Peninsula. Multiple aftershocks as strong as 6.9 magnitude were recorded.

The quake caused damage to buildings and cars swayed in the streets in Petropavlovsk-Kamchatsky, which also had power outages and mobile phone service failures. Russian news agencies quoted the regional Health Ministry as saying several people sought medical help in Kamchatka after the earthquake, but no serious injuries were reported.

The earthquake appeared to be the strongest anywhere in the world since the March 2011 earthquake off northeast Japan that was 9.0 magnitude and caused a massive tsunami that set off meltdowns at a nuclear power plant. Only a few stronger earthquakes have ever been measured around the world.

The tsunami alert disrupted transportation in Japan. Ferries connecting Hokkaido and Aomori on the northern tip of Japan's Honshu island were suspended, as well as those connecting Tokyo and nearby islands, and some local train operations were suspended or delayed, according to operators. Sendai airport temporarily closed its runway.

Japanese nuclear power plants reported no abnormalities. Tokyo Electric Power Company Holdings, which operates the tsunami-affected Fukushima Daiichi nuclear power plant, said about 4,000 workers are taking shelter on higher ground at the plant complex while monitoring remotely to ensure plant safety.
