Tsunami waves have reached the US west coast after a 8.8 magnitude earthquake off Russia's eastern coast triggered warnings across the Pacific - here's a list of the areas affected
The earthquake, which hit near Kamchatka Peninsula at about 11:25am local time (00:25 BST) on Wednesday, is one of the most powerful ever recorded
Residents have been describing the moment the earthquake hit, with one telling the BBC: "Chaos broke out, furniture started falling before our eyes"
Tsunami warnings have since been downgraded in Japan, Russia and Hawaii - almost two million people had been told to evacuate in Japan
Meanwhile, Russian authorities have evacuated the town of Severo-Kurilsk after 4m (13ft) waves flooded the port - BBC Verify's been analysing footage from the area

Further tsunami warnings have also been revised in Guam and the Commonwealth of the Northern Mariana Islands.
The advisory has been cancelled by the Pacific Tsunami Warning Center.
"There is no further tsunami threat to Guam, Rota, Tinian or Saipan," the agency says.
The tsunami warning covering Hawaii has been downgraded to an advisory level, the Pacific Tsunami Warning Center says,
This means there is the potential of strong waves, minor flooding and strong currents, but that a major tsunami is not expected to hit. Those evacuated may return home, Hawaii Emergency Management Agency director Stephen Logan says.
People are advised to drive slow and be safe, while watching for flooding in some areas.
A tsunami advisory has been issued for most coastal areas of British Columbia, Canada's most western province.
Residents are advised to avoid the ocean, follow official instructions and and wait for the all clear.
A tsunami threat alert has been issued for parts of the South Pacific, including Papua New Guinea, Solomon Islands, and Vanuatu.
The warning comes from the US's National Oceanic and Atmospheric Administration (NOAA).

Reporting from Los Angeles
It’s the early hours in Los Angeles. I’m still awake watching local news - we've heard that waves have reached the shore, but it seems like things could be minimal for the most part along the US West Coast.
I was at Manhattan Beach in Los Angeles County earlier today as news broke about the earthquake and tsunami threat.
George Mejia, 25, and his two cousins were packing up their longboards in their convertible when his mom called.
“She said, ‘Did you see there was a huge earthquake and there’s maybe gonna be a tsunami?’ I was like, ‘No, I’ve been in the water!’”
Instead of speeding off, the trio sat in their car and peered out at the ocean, talking about heading back in and riding tsunami waves.
Down on the sand, Heath Macleod, his wife and their two girls were finishing up their beach day at Manhattan Beach in Los Angeles County when I asked them about the earthquake and tsunami threat.
Instantly, their youngest daughter burst into tears, prompting him to say “I guess we better tail it out of here”.
Blue tsunami evacuation route signs line many roads along the US West Coast, informing those in these areas of a safe route to avoid a potential disaster.
The tsunami has reached the coast of California, according to the US National Weather Service.
It's showing up in Arena Cove and Monterey in the north of the state, making its way further down, the service adds.

The Jayapura City Disaster Management Agency in Papua has issued an appeal to coastal residents to evacuate to higher ground.
This is in response to the 8.8 magnitude earthquake off the east coast of Kamchatka, Russia. Residents and tourists in the capital of Indonesia’s easternmost province are not allowed to approach coastal areas. Fishermen are also advised not to go out to sea.
A local journalist tells the BBC Indonesian service that he saw several people from the coastal areas of the city heading to higher ground.
Previously, the Indonesian Meteorology, Climatology, and Geophysics Agency issued a tsunami early warning for parts of eastern Indonesia.
The warning covers coastal areas in North Sulawesi, North Maluku, West Papua, and Gorontalo. Authorities have urged residents to remain calm and avoid the shoreline.
Macclesfield resident Rachael Burrows is on a cruise ship off the coast of Hawaii.
She tells BBC Breakfast that they got the emergency warnings on their phone while on a tour.
The first one told them they were in immediate danger, she explains, and they started making their way back to the ship.
She says shops were closing and the traffic got bad. "It was quite scary because all the sirens started going off," Burrows says.
"Everyone was just running" to get on the ship, she says, adding that she was one of the last allowed back onto the ship before it moved back out to sea, with those left behind told to move to higher ground.
Tsunami alert sent tourists 'running', says Brit on Hawaii cruise

We're seeing more waves reaching the Hawaiian coast on the Pacific Tsunami Warning Center.
A wave reaching 5.7ft (1.74m) has been recorded at Kahului, Maui, while one of 4.9ft (1.5m) was recorded in Hilo, Hawaii.
As we've been reporting, the powerful 8.8 magnitude earthquake struck off the coast of Russia's far eastern Kamchatka peninsula earlier, prompting evacuations and tsunami alerts across parts of the Pacific coast.
Russian state television has aired footage of tsunami waves sweeping through a coastal town in the far east of the country, carrying buildings and debris into the sea.
We've gathered some of the latest images from Russia which you can see below.

Japan's Meteorological Agency says tsunami waves have reached parts of the country’s coast.
The areas include the Fukushima, Miyagi and Iwate prefectures, the agency said in a live map on its website, which adds that it expects waves could reach as high as 3m (9ft).
The tallest wave so far recorded is 1.3m (4ft), observed at Kuji Port in Iwate Prefecture, the agency says.
Thousands of people have been told to evacuate for their safety, while the public broadcaster NHK says there are no reports of major damage so far.
China has just lifted its tsunami alert on Shanghai and Zhejiang.
Taiwan's alert still remains.

The US Tsunami Warning Centres says waves of more than three metres high are possible along some coasts of Ecuador, the northwestern Hawaiian islands and Russia.
Waves between one to three metres are possible along some coasts of Chile, Costa Rica, Hawaii, Japan and islands in the Pacific, it adds.
Waves of up to one metre were possible elsewhere, including Australia, Colombia, Mexico, New Zealand, Tonga and Taiwan.
Japan says its citizens should be on high alert, and 1.9 million people are under evacuation orders.
Hawaii is on full tsunami alert, with people told to get to higher ground and ships asked to remain offshore. The mayor of Honolulu has told residents: "Please take this very seriously. Get yourself as high as you possibly can" though says authorities are yet to see "a wave of consequence"
On the US west coast, the US National Weather Service is telling people to avoid beaches, harbours and marinas.
Chinese authorities have issued a tsunami alert for Zhejiang province and Shanghai city, saying they expect waves of up to one metre.
In Peru, officials have issued a tsunami warning and are keeping "constant surveillance” on the situation.
As we've just reported, a wave of 4ft has been recorded at Haleiwa, Oahu.
In the latest update from the island's emergency management, people are warned to remain outside the evacuation zone until further notice.
It adds that tsunami waves are currently impacting the state and the tsunami warning remains in effect.
They are told not to re-enter until officials say it's safe, the update adds.
The evacuation zone wraps around the entire coastline.

For the last 30 years, David Dorn has lived one block away from the ocean in the coastal city of Kihei in Maui, and is no stranger to tsunami warnings.
Dorn, 60, tells the BBC that he and his wife are treating this one differently.
“We try and take them all seriously, but most people kind of take them a bit lightly,” he says about the tsunami sirens which have been blaring since the alert first went out.
But now he and his wife are packing their two cats into their van, in which they plan to sleep in tonight after seeking higher ground at an inland shopping centre.
Before leaving, he’s moved his electronics up to his loft, hoping that even if seawater penetrates the building it won’t reach the rafters.
For now his biggest concern is traffic, as toppled electric poles could prevent cars from leaving.
“Traffic’s always a problem and its getting worse. And its at its worst in any emergency like this,” he says.

A tsunami alert in the Fukushima area always triggers a heightened sense of concern because of the 2011 triple disaster that resulted in the nuclear meltdown.
The Tokyo Electric Power Company (Tepco) was one of the first organisations to update that all its workers had been evacuated earlier today – with no abnormalities reported so far.
This is still an area of concern – because there’s still nuclear debris that’s being constantly cooled by tons of water that then gets stored in huge tanks next to the plant.
Japanese authorities have evacuation plans in place for those within 20 kilometres of the plant, and recommend sheltering and staying put for those 20 to 30 kilometres away.
We’ve seen grid locks and traffic jams as people try to evacuate affected areas – major train lines are still partially closed along the coastal areas.
Hawaii resident Kelsea Sheppard was speaking to the BBC a little earlier when tsunami alerts interrupted the interview.
Watch the moment the sirens rung out below:
Josh Green, governor of Hawaii, is now giving an update.
"So far we have not seen a wave of consequence," he says, but they have seen significant water recede.
Wave activity hasn't come past the island of Hawaii, he explains, and they expect it will be at least two to three more hours until they can give the "all clear".
We're getting more details on the waves that are hitting Hawaii now, with the tallest wave measured by the Pacific Tsunami Warning Center recorded at Haleiwa, Oahu.
It was 4ft (1.21m) tall, the centre says, with 12 minutes recorded in between waves.
