I heard this earlier, but latest I have heard was that water went six mile inland.... I don 't know which is correct, but even six miles is devastating....

6 miles sounds like it makes more sense.

no i thought i heard 65 miles inland too
maybe bad reporting by news people

It changed time in the world.

Earth's day length shortened by Japan earthquake - CBS News

I told my 16 yo last night as we watched videos and pictures that this is probably the largest disaster to strike in my entire life and quite possibly his and it's going to get alot worse before it gets better. Radiation clouds can easily cross the Pacific...

I'm betting at the minimum there will be another VERY large quake somewhere on the other side of the ring of fire within the next few months...



I have a question that I haven't been able to answer.... Maybe Mr Oakley can chip in with some professor geoisms...

If there was a mile wide whirlpool that was s#^&#^&#^&#^&#^&g down sea water....where does the water go..does it stay underground now forever and does the ocean level now drop because of the water? Or does it maintain the level of ocean height and filter back into the environment?

It actually displaces the water, which generates the energy for the tsunami. If you imaging the length of the fault, x the displacement (8ft) all of the displaced water does not go into the crust.

it is a subduction zone, and water circulates down into the earth (crust and mantle) as the ocean floor is subducted under Japan, but it is mostly in the pore spaces of the sediment on the ocean floor and in the cracks in the underlying rocks..

but.. caveat.. I'm a glacial/coastal guy.. not a seismologist!

what are they gonna do with this enormous amount of debris?

i mean they are an ISLAND and allot of the material was imported
over many years so that means huge Barges and euks trucks hauling it where
to the ocean? China wont touch it now that it's radio active.

So is the speed of the tsunami, english meaning is death wave, like a wave going thr speed of sound minus the friction caused by the water itself.

8.9 quake!!!!!! I never heard of one even close to that. That scale is logarithmic , 8.9 is incredible.

Lots of concerns about what may happen next saturday or around that date with the moon so close and the perfect alignment. I read somewhere that the earths crust could be distorted as much as 1 percent. 1 percent doesn't sound like much but 1 percent of something as large as the earths crust is a big deal. Could be the moons pull as it gets closer that has cause this huge quake.

10X in shaking for every number but I heard today 32X in energy for every number increase? Never heard it expressed that way.

Mag 1 = 6 oz TNT
Mag 9 = 6 x32x32x32x32x32x32x32x32/(16*2000) = 200 Million TONS TNT

Great news. Relieved to hear this.

Lots of deaths, been hard to follow at the show.
