British tourists were caught in a frightening situation as cruise ships deserted ports following tsunami warnings. This came after a powerful 8.8-magnitude earthquake struck near Russia early this morning.

Authorities issued evacuation orders in Hawaii, Japan, Russia, Colombia, and parts of the U.S. West Coast when the earthquake occurred off Russia’s eastern Kamchatka Peninsula, generating 15-foot waves across the Pacific Ocean.

Panicked tourists took to social media to share their desperation as cruise ships appeared to hastily depart from Hawaii without passengers. 

One TikTok user, @demifreeman, posted a video of people frantically running down a port towards their ship on the social media site.

The clip said: ‘POV: tsunami in Hawaii and your cruise is leaving without people. Actually insane.

‘Actually insane,’ the passenger said in the caption, adding: ‘We are going to be in the middle of the tsunami in the ocean.’

The US Tsunami Warning Centers advised that waves over three meters above tide levels could impact certain coasts of the northwestern Hawaiian islands.

Governor Josh Green said flights in and out of the island of Maui had been cancelled as a precaution, before authorities cancelled a coastal evacuation order.

Still, authorities are bracing for tsunami waves to reach the U.S. mainland, with 3.6ft waves observed in California. Near the epicentre in Russia, waves reached highs of up to six metres (nearly 20ft), local experts said.

In Hawaii, video shared by @mandythecruiseplanner appeared to show a bus load of people who had missed a cruise in Hawaii as holidaymakers desperately scrambled to avoid to fallout.

‘So we made it to the port, but the ship is leaving,’ Mandy explained. 

She added: ‘The ship is leaving and now we’re going to higher ground and people are upset, and this is not me making light of the situation, this is me just saying it’s crazy, it’s chaos, nobody knows what’s going on, our bus driver had no idea what’s happening.

‘People on the ship, we have family on the ship, they’re terrified for us. We’re terrified for us.’

The holidaymaker shared how other passengers were coping, describing how some were even ‘crying’.

She said: ‘We’re going to be going to higher ground now, I’ll keep you posted about what’s happening, I did not expect this. 

‘People are crying, we’re going to higher ground, an employer is yelling at people, people are yelling at the employee, this is crazy.’

She finished with: ‘I love you guys, I’ll keep you posted, keep the faith. 

‘This is the first time I’ve ever not made it to the ship and I’m worried for all the kids, the kids are just terrified on the ship and communication is not great.’ 

British tourist Rachael Burrows, from Macclesfield, Cheshire, was also forced to rush back to a cruise ship on Hawaii before it left for safer waters this morning.

She told BBC Breakfast: ‘We were on a tour around the volcanic area of the Big Island.

‘Towards the end of the tour, as we were luckily heading towards the cruise ship, we started getting emergency warnings sign on our phones.

‘The first one was tsunami you are in immediate danger, you need to move away from the coast to higher ground.’

The tour guide was at first dismissive of the warning, saying they happened all the time and it ‘won’t be anything’.

Ms Burrows added: ‘We started getting more through saying times when the tsunami would hit.’

Suddenly, she said, they were told it was time to go. Their outing on the island was cut short and passengers hurried back to the ship.

‘It was quite scary because all the sirens started going off in the area,’ Ms Burrows said. 

‘We were luckily some of the last ones to get on the cruise ship. Then we could see a lot of other people getting dropped off and lining up, but they didn’t make it.

‘They were then told to get to higher ground on shore.’

Speaking to Sky News, Ms Burrows said that 600 passengers were left stranded on Big Island in Hawaii. 

‘The tour operator just messaged to say 600 people didn’t get onto our ship. They were then told to find refuge at higher ground. So it was quite scary. 

Hawaii locals desperately evacuated to higher ground on Wednesday after the quake struck off Russia, pushing 15ft waves out across the Pacific. 

The Hawaii Emergency Management Agency advised residents to remain at least 100 feet away from inland waterways or marinas connected to the ocean due to wave surges and possible flooding. 

‘If possible, remove or deploy vessels to deep water,’ the agency said. 

The Pacific warning centre has since downgraded the Hawaii tsunami alert to ‘advisory’ and said it was safe for residents to return to evacuated areas.

A major tsunami is not expected to strike the U.S. state of Hawaii, the Pacific Tsunami Warning Center (PTWC) said in an update, and there were no reports of major damage.

But authorities have started observing abnormally large waves off the coast of U.S. states.

Oregon has seen a maximum observed wave height of 1.4ft, at Port Orford, while Washington state has seen tsunamis of up to 0.7ft, at Charleston.

Crescent City, in California, has seen waves measuring up to 3.6ft so far. Adak, in Alaska, saw 2.7ft waves.

U.S. monitoring organisations were urging people to stay away from the coastline. The Los Angeles weather service said there was a rapid and damaging surge in water level, fluctuating from low to high tide ‘in just a few minutes’.

‘Do not return to inundated areas as waters will recede, but could return multiple times through the next 24 hours, and the first wave may not be the largest,’ it said. 

Waves of up to four metres were expected to hit the Marquesas Islands in French Polynesia in the early hours of Wednesday, local authorities said.

It added that the islands of Ua Huka and Hiva Oa are also expected to be affected.
