I agree a release of such energy there must have built up more energy somewhere else one would think.
and moved the Earth's axis 4 inches...!?!
Read that and more here:
http://www.cnn.com/2011/WORLD/asiapcf/03/12/japan .earthquake.tsunami.earth/index.html?hpt=T1
If anyone hears which way the island and the axis got moved, do say.
in all seriousness, that's exactly what I didn't want to hear. God damn it
Nuclear power as a replacement for our primary source of energy (replacing oil) needs to be reconsidered. Although Oil Spills are terrible for the environment, nuclear power plant accidents are FAR worse.
Solar, wind, tide, and geothermal all have their issues still. However, nuclear power plant disasters are just..just ridiculous. Potential for total destruction of life.
We have none of such yet. We cannot discern the impact without the impact-er. Let's hope we don't have to do so. I anticipate that sea water will help us. Last resort..........Think positive.............
I really don't know anything more than what reading I've done today, but what you say makes sense. I wonder if the powers that be have thought of using the Gamma ray telescope. Maybe turning and looking back through Earth's atmosphere would be somehow prohibitive. Who knows? Good thought.
2 total reactors face meltdown, not 3. #1 & #3 reactors.
To say "2 other reactors" means there's another, #1 that's been known for a while now. CNN should have said 2 reactors.
Axis moved 25 km or 10 inches.
So what does this mean for someone like myself in California?
Thanks!
Got link?
10" sure is a lot!
CNN says it was 10cm or 4".
(I may be a little behind on info;
just got home from a funeral.)
Not sure, I'm not knowledgeable in the nuclear field. I would imagine that the effects would be based on the quantity of release which, atm, is quite minimal.
Good catch. Somehow I read it as cm anyway! Ha!
km would just make my head go boom. ;-D
It would end up turning into corium lava and start melting through the reactor. Maximum temperature isn't maintained for very long as the reaction takes place much quicker. It also depends on how the material disburses. If it pools, it stays hotter longer. If it spreads out, it cools quicker as there is less close contact nuclear material to sustain the reaction.
Unless there is a big pool of material waiting to be spontaneously vaporized/combusted sitting underneath the reactor, then this is NOT going to be worse than Chernobyl. Chernobyl had it's containment vessel blown apart with the core open to the atmosphere being made worse by a massive graphite fire. Those two factors combined to create a massive radioactive plume which distributed radioactive material over a wide area.
And you can get 100x the power without 100x the fuel. Better efficiency and better fuel can give a much better power yield.
Yes, that is correct. But even more ominous is that it seems that parts of Japan are now lower than they were before. Those parts still have water on them. It's been confounding certain experts as to why the water is still pooling in certain areas, but the reality is, Japan has changed forever.
The shifted 8 feet east is all over. Hit google news...
Some are saying that some parts of Japan moved 12 feet east. Other areas, not as much.
Japan's recent massive earthquake, one of the largest ever recorded, appears to have moved the island by about eight feet (2.4 meters), the US Geological Survey said.
"That's a reasonable number," USGS seismologist Paul Earle told AFP. "Eight feet, that's certainly going to be in the ballpark."
...
Kenneth Hudnut, a USGS geophysicist, said experts read data including from global positioning systems to determine the extend of the shift.
"We know that one GPS station moved (eight feet), and we have seen a map from GSI (Geospatial Information Authority) in Japan showing the pattern of shift over a large area is consistent with about that much shift of the land mass," he told CNN.

It's non-zero, but everything is just speculation at this point. And even if it did as long as the containment system remains in place there isn't much to worry about as most of the material will remain relatively contained to a local area.
If it does reach meltdown, best case scenario is for the corium to melt through the floor of the reactor into bedrock where there is no water table. The heat will melt the rock and turn it into a sarcophagus for the corium slag. This would keep the contamination highly localized and easier to manage.
Worst case, there is a large pool of easily vaporized/combustible material sitting under the reactor or inside the reactor chamber. If the corium lava hits this pool at a fast enough rate, then the venting won't be able to keep up with the pressure and the containment vessel will fail. Depending on several factors, that could result in minor plume or become a raging inferno akin to Chernobyl and spread contamination far and wide. This is an unlikely scenario.
Answers:Depends on what you're comparing, most likely, and yes.
Perspective is key here. For our current technology the power output vs. ecological footprint vs. human deaths comparison still favors nuclear power by a significant margin.
What we need to STOP doing is leaving ancient reactors with known flaws running in areas that are susceptible to cataclysms. Or running at all.
TOTAL EXPOSURE ONSET & DURATION OF INITIAL SYMPTOMS & DISPOSITION
30 to 70 R From 6-12 hours: none to slight incidence of transient headache and nausea;
vomiting in up to 5 percent of personnel in upper part of dose range. Mild
lymphocyte depression within 24 hours. Full recovery expected.

immediate medical attention.
Unlikely this would work. Gamma radiation is absorbed by the Earth's atmosphere, so unless there was a MAJOR burst of gamma radiation it is unlikely it would see anything. That's assuming it didn't get blinded by all the other gamma radiation happening due to cosmic bombardments at the top of our atmosphere, the solar wind, etc. in the process.
The real danger from radiation isn't external exposure, but internal exposure. Radiation such as alpha, beta, and gamma radiation don't really travel that far from their source as they react with pretty much anything that gets in their way. In fact, alpha radiation isn't even a danger as a piece of paper or your skin is capable of stopping it. However, if you happen to ingest an alpha emitter you can have some problems. Once a radioactive material is inside the body it can cause all sorts of issues , and most of them hang around for quite some time, especially elements like cesium which can replace sodium and potassium in normal biological processes.
That's not to say there is nothing to worry about when it comes to external exposure. Beta and gamma radiation are capable of penetrating to internal organs, so high enough doses will definitely make you unhappy. But death from external exposure is really hard to accomplish unless you're near the source of radiation. For example, despite the size of the Chernobyl disaster, the only people who died from direct external exposure were those souls unfortunate enough to have gone near the core while it burned (emergency personnel and plant employees).
Thanks. I have a question. Please understand I am not questioning your knowledge or the truth of your words. I am trying to understand what you said.
Are we talking about two different kinds of gamma here? In other words, if the atmosphere absorbs gamma "rays," why worry about gamma "radiation" getting into, or being borne by, Earth's atmosphere?
Isn't radioactive fallout going to be mostly gamma radiation? And we know radioactive fallout can have consequences-at least those of us who are old enough to remember the Cold War know this.
I'd appreciate anyone's attempt at enlightening me here.

Unfortunately, the reactor design they used has no "outer containment" wall. Unlike the TMI design which had a secondary containment dome, the Japanese reactor only has one containment vessel.
The explosion this morning was most likely a result from steam pressure and possibly hydrogen build up from the overheating core. The containment vessel is still intact (you'd know if it wasn't, because it would make a damn pretty light).
I'm not sure what you mean by "already vaporized into the atmosphere". If you're talking about the nuclear materials, then no they wouldn't be. Even in a full open air breach with a raging graphite fire, only a small part of the corium was vaporized and distributed from Chernobyl. Most of it just melted through the floor and eventually cooled off.
It doesn't take much to cause significant contamination, but there's no way the entire fuel load vaporized.

It's not the gamma radiation that is being transported, but gamma ray emitters. Small particles of nuclear materials (nuclear dust) will emit radiation depending on the material type. Plutonium is alpha emitter, cesium is a gamma emitter, and so on. The shorter the half-life of the material, the more radioactive it is.
The problem occurs when these particles accumulate and contaminate an area. This increases the risk of them being ingested or inhaled. Once inside the body, you no longer have the air or your skin or a wall of rock protecting you from radiation exposure. And as I mentioned, a lot of these fission by-products have a tendency to hang out in the body for quite some time, allowing them to do more damage.
Fukushima nuclear plant does NOT have a combustible graphite core like Chernobyl. A total meltdown should flow into underground containment.
Nuclear safety authority: Any radiation from explosion at Fukushima nuclear plant will likely be blown out over Pacific
The don't use graphite. If they did, we'de already have a Chernobyl-like situation on our hands.
Plus, it's a serious breach of nuclear regulations to do so. Only a seriously sociopathic group of human slime would use graphite in this kind of reactor design after Chernobyl.
Please don't post that fallout map, it has been proven to be fake
Did i say they used graphite, let me repeat again....
Fukushima nuclear plant does NOT have a combustible graphite core like Chernobyl. A total meltdown should flow into underground containment.
Government officials have started handing out iodine pills to combat the radiation. Around 3am local time, officials began testing residents living near the Fukushima nuclear plant for radiation poisoning. At least 3 of the 90 randomly selected people tested positive. Residents are being told to stay inside, not drink tap water and keep wet cloths over their faces as radiation levels were still well above safe limits.
It's not the gamma radiation that is being transported, but gamma ray emitters.
Got ya. Thanks!
OKYO -- Japanese officials battling dual disasters raced against time Sunday to contain a potentially catastrophic failure at a nuclear plant while, as the death toll climbed, rescue workers battled a panorama of devastation to locate some of the more than 10,000 unaccounted for following Friday's monster earthquake and tsunami.
After several hours of speculation that a meltdown may be underway at one of Fukushima Daiichi's six nuclear power reactors, Chief Cabinet Secretary Yukio Edano Sunday confirmed that officials believe "there is a possibility that meltdown has occurred" in two units.
He was referring to reactor Unit 1, which was rocked by an explosion Saturday, and Unit 3, which became the subject of great concern Sunday after its cooling system had failed.
He said a nuclear fuel rod had been exposed, but was now covered in water, and stressed that a full meltdown -- which occurs when the tremendous heat from a reactor cannot be cooled, causing part of the internal structure to melt -- was not yet confirmed and officials were battling to contain the damage.
Meanwhile Japanese nuclear plant operator Tokyo Electric Power (TEPCO) said Sunday radiation levels had surpassed the legal limit at Fukushima, describing the situation as an "emergency," broadcaster NHK reported.
And Japan's US envoy insisted there was no evidence of a full meltdown but acknowledged there had been a "partial melt" of a fuel rod.
"There was a partial melt of a fuel rod ... but it was nothing like a whole reactor melting down," Ambassador Ichiro Fujisaki said, according to AFP.
Earlier, Edano confirmed water was being pumped into Unit 1 and Unit 3, and that air was being vented.
"We believe we can stabilize the situation," he added.
He admitted some of the vented air could contain radiation but added "we believe it is a minimal amount" that was not a threat to human health.
He said nine people "may have been exposed to radioactive material." He added that if, as expected, exposure was merely external, it should not be dangerous -- although four of the nine were being checked for internal harm.
Adding to concern Sunday, Japan continued to be hit by aftershocks -- including one of magnitude 6.3 and a 6.1-magnitude tremor striking just 82 miles and 77 miles (124 kilometers) respectively from Fukushima, the US Geological Survey (USGS) said.
A later 6.2-scale tremor -- one of more than 150 aftershocks since Friday -- caused buildings to shake in Tokyo.
On Saturday, an explosion sent huge clouds of smoke billowing into the air at the Fukushima plant, triggering fears of a meltdown on the heels of the 8.9 earthquake -- one of the largest in history -- that spawned a 30-foot wall of water so ferocious it washed away whole towns.

That image is a hoax. The image they use in the lower right corner is the image from the tsunami model. You can check it against the image at the top of the blog. Not too mention that there has been no serious releases of radioactive materials, let alone anything even remotely close to the radiation levels in that image.
The only way you're going to get 300 rads of radiation right now is if you were inside the reactor. The highest reported verified radiation levels are 882 microsieverts, or .882 sieverts with a brief spike to 1.2 sieverts, and that was near the reactors. The 300 rems in the image is equivalent to 3 sieverts. At that level people would be experiencing the unpleasant symptoms of low grade radiation sickness, which they aren't. Only a handful of people have been treated for radiation exposure and that was because they were actually at the plant or near it.
Please verify your information before posting. There is a lot of misinformation, sensationalization, and speculation already.
Sorry, read the conflicting part and thought you were saying that there were two tweets conflictins as to whether or not the core used graphite control rods. It's late. :P
I posted that fallout map yesterday and pulled it down as i found out it was fake.
I did post 2 conflicting tweets. one said any meltdown would flow into underground containments and the other stated it would go into the air over the pacific.
My son has used it. Thought it was okay.
A JAPANESE man who was swept 15km out to sea by Japan's deadly tsunami was plucked to safety today after being spotted clinging to a piece of wreckage, officials said.
A Maritime Self-Defence Force destroyer rescued 60-year-old Hiromitsu Shinkawa after discovering him floating on a piece of roof in waters off Fukushima Prefecture, two days after the disaster struck.
The man, from the city of Minamisoma which has been virtually obliterated, was swept out along with his house after the massive tsunami tore into Japan's northeast following a 9-magnitude earthquake on Friday.
He is conscious and in "good condition" after his rescue which took place around 12.40pm local time, ministry officials said, adding that he was taken to hospital by helicopter.
"I ran away after learning that the tsunami was coming," Shinkawa told rescuers, according to Jiji Press.
"But I turned back to pick up something at home, when I was washed away. I was rescued while I was hanging to the roof from my house."
The government has said that at least 1,000 people are believed to have lost their lives in the disaster, and police estimate more than 215,000 people are huddled in emergency shelters.
However, the police chief of badly-hit Miyagi prefecture, which lies north of Fukushima, said that the death toll was certain to exceed 10,000 in his district alone.
The real embarrassment for the Japanese government is not so much the nature of the accident but the fact it was warned long ago about the risks it faced in building nuclear plants in areas of intense seismic activity. Several years ago, the seismologist Ishibashi Katsuhiko stated, specifically, that such an accident was highly likely to occur. Nuclear power plants in Japan have a "fundamental vulnerability" to major earthquakes, Katsuhiko said in 2007. The government, the power industry and the academic community had seriously underestimated the potential risks posed by major quakes
