    As noted in Wikipedia "Ocean floor shifts created large tsunamis (up to 70 feet (20 m) in height), which resulted in many of the deaths and much of the property damage." Places like Kodiak actually saw that kind of tsunami height.

    Sad/Ironic twist to the Japan Quake, 12 Japanese Firefighters are training with Menlo Park CA FFs for USAR. Some have not been able to locate their families. They have decided to continue their training with Menlo Park Fire on search and rescue. They will deploy with Menlo Park Fire (CATF3) on Military jets if they get activated so they can get back home. CATF3 is the next up to get activated but they are not cleared by the US State Dept for deployment yet.

    Also, at least one person has been swept out to sea in the Crescent City area USCG has set up a rescue mission............the person was WATCHING THE WAVES.

    It does appear that Crescent City harbor got hit hard again. The story in the local paper is here. Because it faces open ocean tsunami's cause damage there. That story also indicates heavy harbor and boat damage in Brookings, Oregon, 26 miles north of Crescent City.

    In the 1964 tsunami the town of Crescent City suffered major damage. The LA Times today did a story that includes a YouTube video of that damage.

    In 1964 police had a hard time getting gawkers to safety before the tsunami hit and 11 died. The local story about today's fatality reads:

    I guess I should note that it's the morning after and the story in Japan is really bad http://www.reuters.com/article/2011/03/12/us-japan-quake-idUSTRE72A0SS20110312

    It's pretty certain that hundreds are dead and hundreds are trapped calling out to be rescued. And then they've got the two nuclear power plants in a "state of emergency."

    New Zealand is still struggling and the Chinese are still coping with a recent quake.

    The Pacific Rim is hot right at the moment....

    I see absolutely no need to be snarky. Hawaiian Islands is a long strip stretching all the way from Niihau/Kauai to Hawaii; and the epicenter was near Sendai (North East Honshu). Depending on which Hawaiian island you draw the line with, I can see it stretching anywhere from coasts of Peru to Chile. So Peru/Chile border was more accurate.

    Anyhow, thankfully the tsunami is now behind us and the damage to any of Americas (North/South) coast was minimal. In California, I heard of minor incidents in Half Moon Bay, Pacifica, Santa Cruz as well as up North in Crescent City near Oregon border.

    In Japan on the other hand, as expected it's going to be a long recovery effort. :(

    Both reactors should be OK ,but right now they both are boiling like a pressure cooker and releasing steam with a small amount of radio activity.

    The main concern now is to keep the water pumps working,and to have plenty of back up power for those pumps.

    The direct path from the epicenter to Santiago, Chile runs the length of the islands. Pick any island ... they are pretty much lined up and any one you pick just pulls the line further south in Chile.

    Santiago - perhaps further south. Nowhere near Peru. Perhaps you have the orientation of the Hawaiian islands turned 90 degrees on your globe?

    In any case ... it is good to see minimal damages outside of Japan. The world can keep the focus there where there is the most need.

    Many news reports now say "the Kyodo News Agency" reports. You can go to the source such as this page. From that story:
    Not very positive news for those waiting to find out about relatives and those who must do the rescue, cleanup, and recovery.

    Also they report:
    Still not good, but better than the whole core blowing up.

    CNN reporting officials in Japan say a Nuclear meltdown may be in progress. Although there is actually no such thing (in NEA terms) as a meltdown, and its more of a term used by laymen, it sure doesnt sound good for a nuclear core to burn through the bottom of the containment building. I always wondered (but dont want to find out) how far into the earths crust it would go before it stopped. In this case, if it gets just a little bit through the crust, and hits the water table, which is right on the ocean, I can imagine the steam release will blow the entire core up like a cork in a bottle.

    Sure bodes badly for additional nuclear plants being built in the US.

    I read one article that mentioned four missing trains that were on the move at the time of the quake. Kept Googling until a couple of articles mentioned they've found one, then I saw this picture:

    I've been watching NHK World English. Really solid reporting, interesting analysis, etc.

    It's been active off and on for a couple of months, but had been dormant the past two weeks. Of course now it would start launching projectiles and creating a need for another public safety response.

    It makes one begin to wonder who in Japan failed to make a timely sacrifice to the gods? I can't imagine what's going on in the offices of their equivalent to FEMA.

    The whole "China Syndrome" thing is pretty much a myth. The core produces heat after shutdown, but this heat does not continue to generate indefinitely. It is called decay heat, and it decays away over time. The worst time is the first 48 hours, after that the amount of decay heat generated is minimal, although the core needs cooling for several weeks to prevent overheating.

    The current situation strongly suggests they have had some melting of the core, as the hydrogen explosion is probably a result of a zirconium/water reaction that occurs at about 1300 degrees and rapidly heats the surrounding metal past the melting point of the zircalloy (around 2200 degrees).

    If people actually understood what was happening...these plants performed at or above design specifications...deaths as a result of this accident will be minimal/non-existent.

    I am just curious why they did not mount the diesel generators on TOP of the containment buildings, knowing they were in a tsunami area, and that the odds of a tsunami following an earthquake was a very real possibility.

    Another thing that comes to mind, is that since the heat continues for 48 hours after the shutdown, why they couldnt have designed the plant to divert this steam to a secondary (smaller) turbine, to generate electricity for the plant itself, as it was shutting down. It would seem their shortfall here was underestimating the results of a major earthquake while located right on the oceanfront.
