On National geographic they have been showing a series of documentaries related to the March quake. Since Japan had such an extensive system of seismographs, the amount of information gathered is unprecedented. This is very helpful, especially when it come sto understanding phenomena like tsunami and liquefaction, which did not act completely as per textbook expectations.
A couple of items called my attention from the last documentary:
The quake lasted 5 minutes… That is 5 minutes of 9 force. Yet, “the milions invested in seismic preparation paid off for Tokyo, as its buildings were not damaged”. The tsunami and the energy infrastructure are another story…
That village with the 10 meter walls had a 10 meter tsunami, and otehr places with tsunami walls. The walls could not witstand it because, and this is the kicker, the coast sunk 2 meters or more in some areas when the quake struck, so their defenses were actually lower. Subsidience they called it. So many areas were already under sea level when the waves struck. That was a wild card they were not ready for. As to why it hit north, then south, then north again, I did not understand the explanation.
Oh, and some lovely, never before captured on film, footage of the liquefaction in a park plus the cracks opening and closing. The land under your feet is not as solid as you think after all…

I get this email from a neo Commie pal from college, regarding how HAARP was use dto convince the Japanese government to support whatever imperialist strategy in teh Middle east/financial control/whatever. Sigh and double sigh I think, and erase the thing.
Lo and behold, I rturn on the TV and there is Donshen -Eastern TV- radcasting the same #$%#%^& nonsense.
EDIT:
and to prove their point, they claim the taiwanese satellite saw a decrease in the ionosphere over the quake area…[/quote]
I have no idea how the ionosphere relates to other things, but some observations that were made just prior to the quake showed upper-atmosphere heating. They are theorizing that radon gas was released over the days just prior to the quake, causing the heating. There was some talk that this may be a way of getting early warning of major quakes.
