UPDATE:
-the explosion was caused by hydrogen between the reactor buildings
-primary containment and reactor vessel are intact and fine
-they well be pumping boron treated seawater to the vessel

Damn, son! Where'd you find this?
There's very little information coming out from the Japanese government about this problem. They tend to "downplay" these incidents but experts are split on the seriousness of this situation.
The Japanese PM assured the world that not one person was affected by radiation (except of course the 4 workers who got blown inside the power plant). But it might just be a way to calm people down. But the world is watching....
Grabe itong super earthquake na tumama sa Japan. Nakakabagabag ng kalooban panoorin yung mga imahe ng trahedya, sa CNN, BBC, Aljazeera, internet, etc.
I just pray things get better instead of worse -- especially that nuclear power plant. Huwag naman sana umabot sa meltdown.

no worries about the nuclear meltdowns, it's now the era of comic book movies so timing lang yan we will have superheroes soon
Keeping the public in the dark lead to speculation of what exactly is happening at the Fukushima Dai-ichi plant no. 1.

TOKYO – Inside the troubled nuclear power plant, officials knew the risks were high when they decided to vent radioactive steam from a severely overheated reactor vessel. They knew a hydrogen explosion could occur, and it did. The decision still trumped the worst-case alternative — total nuclear meltdown.
At least for the time being.
The chain of events started Friday when a magnitude-8.9 earthquake and tsunami severed electricity to the Fukushima Dai-ichi nuclear complex 170 miles (270 kilometers) northeast of Tokyo, crippling its cooling system. Then, backup power did not kick in properly at one of its units.
From there, conditions steadily worsened, although government and nuclear officials initially said things were improving. Hours after the explosion, they contended that radiation leaks were reduced and that circumstances had gotten better at the 460-megawatt Unit 1. But crisis after crisis continued to develop or be revealed.
Without power, and without plant pipes and pumps that were destroyed in the explosion of the most-troubled reactor's containment building, authorities resorted to drawing seawater in an attempt to cool off the overheated uranium fuel rods.
Robert Alvarez, senior scholar at the Institute for Policy Studies and former senior policy adviser to the U.S. secretary of energy, said in a briefing for reporters that the seawater was a desperate measure.
"It's a Hail Mary pass," he said.
He said that the success of using seawater and boron to cool the reactor will depend on the volume and rate of their distribution. He said the dousing would need to continue nonstop for days.
Another key, he said, was the restoration of electrical power, so that normal cooling systems can be restored.
Officials placed Dai-ichi Unit 1, and four other reactors, under states of emergency Friday because operators had lost the ability to cool the reactors using usual procedures.
An additional reactor was added to the list early Sunday, for a total of six — three at the Dai-ichi complex and three at another nearby complex. Local evacuations have been ordered at each location. Japan has a total of 55 reactors spread across 17 complexes nationwide.
Officials began venting radioactive steam at Fukushima Dai-ichi's Unit 1 to relieve pressure inside the reactor vessel, which houses the overheated uranium fuel.
Concerns escalated dramatically Saturday when that unit's containment building exploded.
It turned out that officials were aware that the steam contained hydrogen, acknowledged Shinji Kinjo, spokesman for the government Nuclear and Industrial Safety Agency. More importantly, they also were aware they were risking an explosion by deciding to vent the steam.
The significance of the hydrogen began to come clear late Saturday:
_Officials decided to reduce rising pressure inside the reactor vessel, so they vented some of the steam buildup. They needed to do that to prevent the entire structure from exploding, and thus starting down the road to a meltdown.
_At the same time, in order to keep the reactor fuel cool, and also prevent a meltdown, operators needed to keep circulating more and more cool water on the fuel rods.
_Temperature in the reactor vessel apparently kept rising, heating the zirconium cladding that makes up the fuel rod casings. Once the zirconium reached 2,200 degrees Fahrenheit (1,200 Celsius), it reacted with the water, becoming zirconium oxide and hydrogen.
_When the hydrogen-filled steam was vented from the reactor vessel, the hydrogen reacted with oxygen, either in the air or water outside the vessel, and exploded.
A similar "hydrogen bubble" had concerned officials at the 1979 Three Mile Island nuclear disaster in Pennsylvania until it dissipated.
If the temperature inside the Fukushima reactor vessel continued to rise even more — to roughly 4,000 degrees Fahrenheit (2,200 Celsius) — then the uranium fuel pellets would start to melt.
According to experts interviewed by The Associated Press, any melted fuel would eat through the bottom of the reactor vessel. Next, it would eat through the floor of the already-damaged containment building. At that point, the uranium and dangerous byproducts would start escaping into the environment.
At some point in the process, the walls of the reactor vessel — 6 inches (15 centimeters) of stainless steel — would melt into a lava-like pile, slump into any remaining water on the floor, and potentially cause an explosion much bigger than the one caused by the hydrogen. Such an explosion would enhance the spread of radioactive contaminants.
If the reactor core became exposed to the external environment, officials would likely began pouring cement and sand over the entire facility, as was done at the 1986 Chernobyl nuclear accident in the Ukraine, Peter Bradford, a former commissioner of the U.S. Nuclear Regulatory Commission, said in a briefing for reporters.
At that point, Bradford added, "many first responders would die."
Still speculating whether a meltdown is in progress or not...

Tokyo (CNN) -- A meltdown may have occurred at at least one nuclear power reactor in Japan, the country's chief cabinet secretary, Yukio Edano, said Sunday, adding that authorities are concerned about the possibility of another meltdown at a second reactor.
"We do believe that there is a possibility that meltdown has occurred. It is inside the reactor. We can't see. However, we are assuming that a meltdown has occurred," he said about the No. 1 reactor at the Fukushima Daiichi nuclear facility.
"And with reactor No. 3, we are also assuming that the possibility of a meltdown as we carry out measures," Edano said.
Edano's comments confirm an earlier report from an official with Japan's Nuclear and Industrial Safety Agency, who said, "we see the possibility of a meltdown."
"There is a possibility, we see the possibility of a meltdown," said Toshihiro Bannai, director of the apan's Nuclear and Industrial Safety Agency international affairs office, in a telephone interview from the agency's headquarters in Tokyo. "At this point, we have still not confirmed that there is an actual meltdown, but there is a possibility."
A meltdown is a catastrophic failure of the reactor core, with a potential for widespread radiation release.
May kumpyansa ako sa mga Hapon, kaya nilang gawan ng paraan yan or i minimize yung effect.
Btw, kumusta na kaya sina Miss Ozawa and co. I hope they're all ok![]()

Tsunami at Airport
the movement in the earth's axis is a given and this also explains why Japan will always have more earthquakes than us.
contrary to popular belief that there is only one magnetic anomaly region on earth or the so-called deadly triangle otherwise dubbed as the Bermuda triangle, Japan also has its own version of the atlantic triangle which is called the devil's triangle. another location is in russia but this time inland.
the magnetic anomaly regions along with magnetic north pole and south pole (not the true north pole and south pole) always adjust itself in order to change the earth's path or revolution around the sun as was the changing of the axis in the previous event.
now why does this happen? to prevent heavenly object collisions in the not so distant future. i firmly that our ancient ancestors had found a way to change the direction of our mother earth's path to escape major global disasters. the trade off or the collateral damage would be that of the japan event as well as what happened in 2004.
---
regarding the bandah aceh quake, a theory has been proposed that are actually 6 magnetic anomaly regions and not 3 as was mentioned earlier. the 3 were all located on the northern hemisphere so logic will dictate that must be 3 more on the southern hemisphere. but since the southern hemisphere is rarely explored, we have yet not found the magnetic anomaly regions bec. they are in the somewhere in the middle of the vast ocean systems in the south
This is a hoax...
http://www.theweatherspace.com/news/...fakeimage.html(TheWeatherSpace.com) -- A hoax is going around the Internet about a nuclear fallout map, which kills people in the Western United States.
The hoax is going around and has caught a few off guard. The Australian Radiation Services did not issue a fallout map that reaches the Western United States, including Canada.
There is not much to say about this other than it is a hoax. TWS has corrected and pulled the article.

Many homes that washed away are old and made of wood. If those homes were concrete, many would still be standing. Just look at the Sendai airport...
The crazy thing about all of this...
I woke up that morning at around 4:30... I had a nightmare that our house was flooding. A bit unusual, since we live on the third floor.
I think my latent Japanese genes (I'm about 1/4th Japanese) may have been talking to me...
We watched the whole thing unfold that afternoon. Wasn't able to go back to work. Wasn't able to do anything but watch. Was almost in tears when watching the tsunami, something us Lagunenos can relate to...![]()
Ang pagbalik ng comeback...
