A massive earthquake measuring between 8.7 and 8.8 magnitude struck off Russia 's Kamchatka Peninsula early on Wednesday, triggering widespread tsunami alerts and evacuation orders across the Pacific region.
The United States, Japan, Hawaii, and several other Pacific islands were placed under tsunami warnings following the quake, which hit near the city of Petropavlovsk-Kamchatsky in Russia's Far East.
This is the strongest earthquake recorded since 2011 and ties at the sixth most severe quake ever in history, with the 2010 earthquake in Biobío, Chile, and the 1906 earthquake in Esmeraldas, Ecuador, a ccording to the US Geological Survey.
The quake at 8.25am Japan time (11.25pm GMT) had a preliminary magnitude of 8.0, Japan and US seismologists said. Japan and the US Geological Survey (USGS) later updated their measurements to 8.7 magnitude and the USGS said the quake occurred at a depth of 12 miles.
A tsunami with a height of 3-4m was recorded in parts of Kamchatka, said Sergei Lebedev, regional minister for emergencies.
Damage and evacuations were reported in the Russian regions nearest the quake's epicentre on the Kamchatka Peninsula. One of the three waves damaged port infrastructure and pulled several moored ships out into the straits, TASS news agency reported.
Japan evacuated more than 900,000 residents in 133 municipalities along its Pacific coast as the meteorological agency issued advisories saying it expected tsunami waves of up to 3m to reach large coastal areas.
Local officials urged residents to move to higher ground. Initial tsunami waves were reported along northern Japan, with no immediate reports of damage.
Tokyo Electric Power Company (TEPCO), the company which operates the Fukushima Daiichi nuclear power plant, has said that all workers have been evacuated – adding that there were no abnormalities reported so far.
The power plant suffered a nuclear meltdown in 2011 following an huge earthquake and tsunami disaster.
In the US, tsunami warnings and watches were activated for the entire Hawaiian archipelago, vast stretches of Alaska's coastline, and the Pacific coasts of California, Oregon, and Washington. Officials in Hawaii and Alaska advised residents to take urgent action to protect life and property.
Josh Green, the governor of Hawaii, urged residents in low-lying areas to move to higher grounds.
"If you are in a safe place please stay there, and if you're not, please get to higher ground."
Tsunami watches and alerts were also issued for coastal areas and islands spanning the Pacific rim, including Chile, New Zealand, the Philippines, and the US territory of Guam.
Seismologist Dr Lucy Jones told BBC the tsunami could damage harbours and waterfront property in Hawaii - and possibly in California - but it is not expected to cause a catastrophic loss of life anywhere in the Americas.
'It's not a wave,' she said. 'That's how much the sea level rises temporarily.'
As of Wednesday morning, emergency agencies across the Pacific had not reported major injuries or damage outside the immediate impact area. Aftershocks and further tsunami activity remain possible, with authorities urging vigilance in all affected locations.
