It really needed to be that quick because the first waves hit land in a matter of minutes since the epicentre was so close to shore.

What blows my mind is that before boxing day 2004 none of us outside of those often hit "Ring of Fire" countries had any idea how utterly unstoppable and deadly these tsunami waves are. I not lying when I tell you that they are my most common nightmare now, replacing sharks which were the mainstay since my childhood. Thanks for that Spielberg!

That footage is just amazing.  Terrifying, but amazing.

It's the second explosion there to be precise. Although dramatic it is not from the nuclear reactor core. It actually is a steam/hydrogen explosion from the turbine hall. Essentially they can't release steam quick enough to reduce the pressure. The steam valves are physically exploding under the pressure. When I say pressure I mean thousands of PSi.

I visit Nuclear Power Stations on a weekly basis as part of my job and these valves are gigantic. It is clear there is a partial meltdown in process because the heat required to create a continued flow of pressurised steam like this must be very high.

The big risk here is fire. The nuclear core won't explode, it is designed not to. The risk is if the nuclear fuel becomes molten and melts through the reactor floor (as did in Chernobyl). It then creates a deadly mix of nuclear fuel, cement and steel that can catch fire to anything. The repercussions if this happens are on a par with Chernobyl.

Japan no doubt have asked for international help from the US and UK in the form of nuclear experts in an effort to prevent a fire. A fire would shoot nuclear fuel into the atmosphere, the fallout radius would be massive.

Currently the low level radiation being detected is from irradiated steam that contains radio-iodine. Your body tend to absorb radio-iodine in the thyroid gland. If stable Iodine is taken (tablets) it saturates the thyroid and blocks the radio-iodine from being absorbs. I believe the Japanese government have already prescribed this medication to all affected.

they just found 2000 bodies on one part of the cost.

one thing i would say is that i was shock how many of their buildings were built out of wood, the only buildings left standing are brick built.

They're pretty efficient in Japan. Over there if you catch the train to work and the train arrives 1 minute, yes one minute late, you are given a slip of paper by the train company that explains to your boss why you are late. And all because the train arrived a whole 1 minute after its scheduled time.  :D

In other words, their trains are hardly EVER late.

yet they build all the homes on the coast out of wood, sky said that this was spoken about 30 years ago but bricks cost too much at the time and they had lots of wood that cost almost nothing.

That's the wave as it hit. Everyone that was driving on that road are certainly dead now.

Scary as hell ER, unbelievable, I wonder what the  people in the care were thinking when this wave was coming to them.

terrifying stuff... :(

Radiation from Japan's quake-stricken Fukushima Daiichi nuclear plant has reached harmful levels, the government says.

The warning comes after the plant was rocked by a third blast which appears to have damaged one of the reactors' containment vessels for the first time.

If it is breached, there are fears of more serious radioactive leaks.

Officials have extended the danger zone, warning residents within 30km (18 miles) to evacuate or stay indoors.


As radiation levels near the plant rise, people are being checked for exposure
The crisis was sparked by a 9.0-magnitude quake and tsunami on Friday.

'Don't go outside'

On Tuesday morning, reactor 2 became the third to explode in four days at the Fukushima Daiichi plant - 250km (155 miles) north-east of Tokyo.

A fire also briefly broke out at the plant's reactor 4 on Tuesday and is believed to have led to radioactive leaks.

Reactor 4 had been shut down before the quake for maintenance but its nuclear fuel rods are still stored on the site.

Radiation levels in the Japanese capital were reported to be higher than normal, but officials said there were no health dangers.

In a televised address, Prime Minister Naoto Kan said: "There is still a very high risk of more radiation coming out."

He added that the last remaining people within the existing 20km (12 mile) exclusion zone around the plant must leave.

Those living between 20km and 30km were also at risk and should not leave their homes.

"Now we are talking about levels that can impact human health," said Chief Cabinet Secretary Yukio Edano.

He told residents: "Please do not go outside. Please stay indoors. Please close windows and make your homes airtight.

"Don't turn on ventilators. Please hang your laundry indoors."

No-fly zone

Japan also announced a 30-km no-fly zone around the reactors to prevent planes spreading the radiation further afield.

Radiation levels around Fukushima for one hour's exposure rose to eight times the legal limit for exposure in one year, said the plant's operator, the Tokyo Electric Power Co (Tepco).

The radiation reading at 0831 local time (2331 GMT) climbed to 8,217 microsieverts an hour from 1,941 about 40 minutes earlier, Tepco said. The annual legal limit is 1,000 microsieverts.

Shares on the Tokyo stock exchange plummeted 14% before recovering slightly. The leading Nikkei index ended the day 10.55% lower. It had already fallen by 7% on the previous day.

On Monday, a hydrogen blast at the Fukushima plant's reactor 3 was felt 40km (25 miles) away. It followed a blast at reactor 1 on Saturday.

All explosions have followed cooling system breakdowns. Engineers are trying to prevent meltdowns by flooding the chambers of the nuclear reactors with seawater.

Japan's nuclear safety agency said it suspects Tuesday's blast may have damaged the vessel that holds reactor 2.

The BBC's Chris Hogg in Tokyo says that would make it a more serious incident than the previous explosions, which were thought just to have damaged the buildings that housed the reactors.


Meanwhile, five days after the tsunami triggered by the earthquake, the relief operation is continuing.

The latest official death toll stands at about 2,400 - but some estimates suggest at least 10,000 may have been killed.

Thousands are still unaccounted for - including hundreds of tourists - while many remote towns and villages have not been reached.

More than 500,000 people have been made homeless.

The government has deployed 100,000 troops to lead the aid effort.

The UK Foreign Office has updated its travel advice to warn against all non-essential travel to Tokyo and north-eastern Japan. British nationals and friends and relatives of those in Japan can contact the Foreign Office on +44(0) 20 7008 0000.

Mother Nature really is amazing, incredibly powerful its frightening. Someone must have p!ssed her off big time, must be on her period or something

Things like this make me ridiculously thankful that I'm fortunate just to live somewhere where I'm in good health and the risk of natural disasters like this are extremely low.

Heart goes out to everyone affected by the quake
All round the fields of Anfield Road
Where once we watched the King Kenny play (and could he play!)
