Japanese earthquake / tsunami discussion

CNN TV is gone sh1te again, showing the same footage over and over

Important point of note about the range of this Tsunami: it's to be expected. This one from 2009 traveled extremely far. It was an 8.1

If you look a little down the page there is a shockwave animation that is fairly interesting.

Definitely the effect of the moon. Sure it's not as if earthquakes ever happen around the Pacific ring of Fire.

Caused Tsunami effects and damage on Irish coastal areas

That was 260 odd years ago. Stretching it a bit.

I had read that a massive earthquake was due in Japan, that meterologists have been waiting for it for the last few years. Apparently these things are cyclic.(

News reports that I have seen this afternoon suggest this is NOT 'theee' massive one they've been waiting for. There's a bigger, even more damaging one due on the Nankai Trough further south west than where the epicenter of today's quake is located.

We do. We have geological evidence of being completely destroyed by 30m tSunamis.

There was a bit of worrying in my house this morning as my brother is in the very south of South Korea, but from what I hear he's alright!

Terrible images coming from Japan. As has been said before the Japanese will recover and fast too. One of the most resilient cultures on earth. Very very sad. The loss of life is going to be pretty huge I imagine. I hope that nuclear plant gets made safe and soon.



It's not another Portugal earthquake that would be the problem(except to Portugal. The last one flattened Lisbon). You're referring to one half of one of the Canary islands that will sooner or later slump into the atlantic, causing an unreal wave. Up to 100 metres.

I saw a documentary on this a few years ago, and this is due to happen within this century. Half of one of the canary islands will fall into the sea, cause a massive tsunami that will have a devestating effect on the east coast of America, from Boston all the way down to Florida.

Time-scale is a little longer, that's all.

You've missed the point. Nobody said the gravitational effect of the Moon is the cause. It just gives an extra nudge.

Any news on how big the waves that hit hawaii are??

It's said to be one of the biggest tsunami's ever recorded. What was the number on the Richter Scale?

And that's all that may be needed.

Not any more there isn't.

Earthquake mechanics basically are that the longer you go without one the bigger the potential energy is when it finally happens. Think of Anti-Lock Brakes in your car, and a bunch of smaller actions vs. one big action. Earth's plates are always moving and in cases where those plates get stuck on eachother it's a good thing if they more frequently nudge/slide across eachother, each time they break loose it's essentially a quake. If plates go a very long time trying to slide against eachother, at some point they will come loose and *snap* almost elastically toward the positions they would be in if there was no friction between those plates. No-longer lining up perfectly of course, a fault-line forms between them - like Nankai.

They will definitely have to re-assess whether a "big one" is still on the table. This may have been it. The record magnitude for an earthquake is 9.5: this was 8.9

The CNN coverage of Hawaii isn't great, anyone got a better stream?

I wonder what M.Ring thinks of this moon theory,I believe his weather forecast's are very accurate & he uses the Moon etc..

Hopefully, for Japan's short term future this does relieve some of the stress. We probably won't know that for a few weeks. Iirc, the Haiti quake actually added to already building up stress rather than relieve it.:(

Jesus Christ. The NHK newscaster on at the moment is seriously struggling with all of this - it's incredible.

You know what conjecture is?

Look at the citation for that line says it all.

On another topic I hope it is a conincidence that amazon sent me a reccomendation for this book this morning @8.40 am (I have a book or two by this author already).

Two waves. Six feet each roughly. No damage reported last I heard. They don't expect a lot to happen. Though there may be some odd refracted waves in among the islands or in certain bays.

6ft waves recorded en route to Northern Hawaii on CNN

RTE News: 1351 Japanese police: Up to 300 bodies have been found floating in the water off the coast of the northestern city of Sendai.

Events like this make me feel really lucky I live in Ireland, and put my extremely minor problems in perspective for me.
