Tsunami waves reach Hawaii after huge quake rattles Russia's Far East

In Hawaii, coastal residents were told to get to high ground or the fourth floor or above of buildings, and the U.S. Coast Guard ordered ships out of harbours as the tsunami approached.

"Take Action! Destructive tsunami waves expected," the Honolulu Department of Emergency Management said on X.

Shortly after 0600 GMT, the Pacific Tsunami Warning Center said 1-1.2-metre waves were impacting the Hawaiian islands.

Hawaii Governor Josh Green said so far no waves of consequence hit the islands but all flights in and out of Maui were cancelled.

Tsunami waves struck parts of Kamchatka, partially flooding the port and a fish processing plant in the town of Severo-Kurilsk and sweeping vessels from their moorings, regional officials and Russia's emergency ministry said.

"Today's earthquake was serious and the strongest in decades of tremors," Kamchatka Governor Vladimir Solodov said in a video posted on the Telegram messaging app. Russian scientists said it was the most powerful quake to hit the region since 1952.

Russia's Ministry for Emergency Services said on Telegram that a kindergarten was damaged but most buildings withstood the quake. No serious injuries or fatalities have been reported.

The U.S. Geological Survey said the earthquake was shallow at a depth of 19.3 km (12 miles), and centred 119 km east-southeast of Petropavlovsk-Kamchatsky, a city of 165,000.

It revised the magnitude up from 8.0 earlier, and reported a series of strong aftershocks up to a magnitude of 6.9.

A resident in the city of Petropavlovsk-Kamchatsky said the shaking rumbled for several minutes.

"I decided to leave the building," said Yaroslav, 25. "It felt like the walls could collapse any moment. The shaking lasted continuously for at least 3 minutes.”

WARNINGS ACROSS THE PACIFIC

Tsunami alarms sounded in coastal towns across Japan's Pacific coast and evacuation orders were issued for tens of thousands of people.

Workers evacuated the stricken Fukushima nuclear plant, where a meltdown following the 2011 tsunami caused a radioactive disaster, operator TEPCO said.

Footage on public broadcaster NHK showed scores of people on the northern island of Hokkaido on the roof of a building, sheltering under tents from the beating sun, as fishing boats left harbours to avoid potential damage from the incoming waves.

Automaker Nissan Motor (7201.T), opens new tab suspended operations at certain domestic factories in Japan to ensure employee safety, Kyodo news agency reported.

Three tsunami waves had been recorded in Japan, the largest of 1.3 metres (4.3 feet), officials said. Japan's Chief Cabinet Secretary Yoshimasa Hayashi said there were no injuries or damage reported so far, and no irregularities at any nuclear plants.

Tsunami waves of between 1-3 metres can be fatal for people who are swept away, said NHK. They can also cause flooding and damage wooden buildings, with people at risk of being killed by large drifting objects, according to the Japan Lifesaving Association.

The U.S. Tsunami Warning System also warned of "hazardous tsunami waves" spreading across the Pacific.

Waves reaching more than 3 metres were possible along some coasts of Russia, the northern Hawaiian islands and Ecuador, while waves of 1-3 metres were possible in countries including Japan, Hawaii, Chile and the Solomon Islands, it said.

Smaller waves were possible along coastlines across much of the Pacific, including the U.S. West Coast.

"Due to a massive earthquake that occurred in the Pacific Ocean, a Tsunami Warning is in effect for those living in Hawaii," U.S. President Donald Trump said in a social media post.

"A Tsunami Watch is in effect for Alaska and the Pacific Coast of the United States."

'RING OF FIRE'

Several people in Kamchatka sought medical assistance following the quake, Oleg Melnikov, regional health minister, told Russia’s TASS state news agency.

In Severo-Kurilsk in the northern Kuril islands, south of Kamchatka, tsunami waves exceeded 3 metres, with the largest up to 5 metres, Russia's RIA news agency reported.

Alexander Ovsyannikov, the town's mayor, said four tsunami waves had passed.

He urged residents to assess damage to their homes and not to use gas stove heating until inspections had been carried out, in order to avoid a risk of carbon monoxide poisoning.

Power to the Sakhalin region had been cut off due to damage to the electricity grid, RIA said, citing the regional governor.

Kamchatka and Russia's Far East sit on the Pacific Ring of Fire, a geologically active region that is prone to earthquakes and volcanic eruptions.

The Russian Academy of Sciences said it was the strongest quake to hit the region since 1952.

"However, due to certain characteristics of the epicentre, the shaking intensity was not as high ... as one might expect from such a magnitude," said Danila Chebrov, director of the Kamchatka Branch of the Geophysical Service, on Telegram.

“Aftershocks are currently ongoing ... Their intensity will remain fairly high. However, stronger tremors are not expected in the near future. The situation is under control.”

 
Japan's Fukushima plant workers evacuate after tsunami warning

Workers at Japan's embattled Fukushima nuclear plant were evacuated earlier on Wednesday after tsunami warnings were issued across the country.

The plant's operator said all 4,000 of its workers had been evacuated, adding that there were no "abnormalities" detected.

It comes after a massive 8.7 magnitude earthquake struck off Russia's far eastern coast, triggering warnings across the Pacific.

For many in Fukushima prefecture, the warning is likely to bring back memories of one of the worst nuclear disasters the world has seen.

In March 2011, Japan was hit by a devastating 9.0-magnitude earthquake and subsequent tsunami that went on to kill more than 18,000 people.

The tsunami flooded the plant, disabling its emergency generators and causing them to overheat - leading to a nuclear meltdown.

Hundreds of tons of extremely hazardous material still remain at Fukushima - and the challenges and controversies surrounding it are still very much present even now, more than 14 years later.

What happened at the Fukushima nuclear site?

On 11 March 2011 at 14:46 local time (05:46 GMT) an earthquake - known as the Great East Japan Earthquake - struck east of the city of Sendai, just 97km (60miles) north of the power plant.

Reactor buildings at Fukushima were damaged by hydrogen explosions caused by the earthquake and tsunami. The tsunami knocked out cooling systems to the reactors, three of which melted down.

The plant also suffered a number of chemical explosions which badly damaged the buildings, and to make matters worse, radioactive material began leaking into the atmosphere and the Pacific Ocean.

The government soon declared a 30km exclusion area around the plant, evacuating more than 150,000 people who were warned not to return due to radiation concerns.

Even now, significant portions of the area are still restricted - with abandoned homes, empty neighbourhoods and faded storefronts to show for it.

Why is it so hard to clean up the nuclear waste?

A total of 880 metric tons of hazardous material - a mixture of melted nuclear fuel and reactor structures - still remain inside the Fukushima plant.

Removing this debris from the reactors is seen as the biggest challenge towards safely decommissioning the plant.

Tens of thousands of workers will be needed over the next 30 to 40 years to safely remove nuclear waste, fuel rods and more than one million tons of radioactive water still being kept at the site. The clean-up is also estimated to cost around 21.5tr yen ($145bn; 3109bn).

Earlier this week, Tepco said the start of full-scale removal of melted fuel debris would be pushed back until 2037 or later - saying that preparations for this would require at least 12-15 years.

The plan has already been delayed numerous times, and the latest delay is a major setback to a government plan to complete decommissioning by 2051.

Tepco still maintains that it can achieve this but some experts have called this into question.

"Who really believes all 880 tons of debris can be removed in 14 years between 2037 and 2051? Maintaining an unrealistic goal is not good when considering Fukushima's recovery," Shunji Matsuoka, a professor of environmental economics and policy studies at Waseda University, had told local news outlet Asahi.

And then there's the issue of water.

Since the disaster, power plant operator Tokyo Electric Power Company Holdings (Tepco) has been pumping in water to cool down the reactors' fuel rods. This means every day the plant produces contaminated water, which is stored in more than 1,000 tanks, enough to fill more than 500 Olympic swimming pools.

But Japan needs the land occupied by the tanks to build new facilities to safely decommission the plant - and in 2023, it began releasing some of this treated wastewater into the ocean.

The plan was met by a huge amount of criticism and controversy, despite the UN's atomic regulators saying it will have a "negligible" impact on people and the environment.

Is Japan shifting back to nuclear power?

In the wake of the Fukushima disaster, Japan initially started moving away from nuclear energy - but the government has slowly started to reverse this policy.

Earlier this year, Japan said it needed to rely on nuclear to meet growing demand from power-hungry sectors like AI and semiconductors, with an energy plan released calling for "maximising" nuclear energy.

And this week, utility company Kansai Electric Power said it would look into whether it could build a new reactor - a project that had been suspended in the wake of Fukushima.

But there has been local opposition to such plans - and Wednesday's tsunami alert is likely to heighten concerns.

Japan's Meteorological Agency says tsunami waves have reached parts of the country's coast, including Fukushima.

Waves could reach as high as 3m (9ft) in such areas and thousands have been told to evacuate for their safety.

Why do so many earthquakes happen in Japan?

Japan's precarious location on the Ring of Fire means it experiences about 1,500 earthquakes a year. The looming threat of earthquakes is ever present.

It is also widely considered to be among the most earthquake-prepared nations in the world. Its citizens begin taking part in earthquake drills from as early on as primary school and its buildings are designed to be earthquake resistant.

Despite this, many in Japan remain fearful of the "big one" - a once-in-a-century quake that worst case scenarios predict could kill as many as 300,000 people, triggering tsunamis of up to 30m (100ft) along the country's Pacific coast.

Experts say there is a 70% to 80% chance of a magnitude 8 or 9 quake striking somewhere along Japan's Nankai trough in the next 30 years.

This is why I do not like living in coastal areas. You are always in danger of tsunami and whatnot.

Anyway, I hope everyone will be safe.
