    elsongs - I'm not sure you got your facts right.

    The 1964 Alaska earthquake was a 9.2 megathrust, the same type as the Japan earthquake. It was between the Pacific and North American plate - and those are the two that go alongside the west cost of the entire US, not just Alaska. Megathrusts are possible in all of the West Coast, and they're typically above 8.0.



    And this is an Alaskan ghost town that was destroyed and where trees were killed by the salt water of the tsunami. Still to this day, trees doesn't grow there, and you can see the dead trees still standing:



    There were tsunamis in the US and Canada as the result of that Alaska earthquake... so tsunamis are possible in the US.


    No, I have my facts right, I studied some geology in school. You simply misread what I said.

    I'd like to know where you got your "Megathrusts are possible in all of the West Coast" statement, when it's simply not true: http://www.latimes.com/news/local/la-me-tsunami-california-20110315,0,7384994.story

    Megathrust quakes are generated where there are subduction zones. Subduction zones are where one plate is forced under another. There are no subduction zones off the coast of California, which is what I was specifically referring to. I am well familiar with the diagram you posted. The boundary between the Pacific Plate and the North American Plate in California is the San Andreas Fault, which is NOT a subduction zone but a strike-slip fault. The plates slide against each other, instead of forcing one plate under another. See the red arrows iover California n the diagram you posted? They are moving in different directions. Now look at the arrows near Alaska and Japan. They are pointed towards each other. I guess you didn't know what they mean.

    Just because a plate is bounded by another, it doesn't meant the geological action is the same all throughout. The Pacific Plate is moving in a northwesterly direction. Off of Alaska and Japan, it is being forced under another plate. Along California, it is sliding with the other plate. in the Southeastern Pacific Ocean, the Pacific Plate is moving away from the other plate.

    A lot of people misunderstand "The Ring Of Fire." It is simply a zone around the Pacific Ocean that is highly geologically active, but the mechanics of that activity differ in various places.

    As for tsunamis, I was talking about earthquakes in California GENERATING tsunamis, which will not happen. Will we receive tsunamis? Of course, it's already been demonstrated on Friday. But they will be generated elsewhere, like off of Alaska or in the Pacific Northwest, or across the ocean.

    Again, you totally misread what I had to say.

      Cool. I had my facts wrong (that's what I get for trusting blogs...). Thanks for clearing that up

        The reactor 4 fire was linked to an explosion earlier that saw the roof crack. Whilst they put that fire out originally, it may have been caused by the release of hydrogen from the heating spent fuel rods. They advised earlier that the pool for keeping the spent fuel rods cool was leaking away (appears to be high in the building near the top of the reactor but otherwise exposed with just the outer top roof (and now crack).

        Some experts have been praying this lot does not over heat and start to burn. News just in is there is another fire. I hope this is not the rods, this will be worse than Chernobyl if so so the experts say...

        They were considering dumping water with helicopter, that would risk damage and exposure etc. They may be forced if it is the rods on fire...

          The people sticking around to work on the reactors in hopes of stabilizing them are heroes.

          Oh, and to the previous post: I sent them money and I'll probably send more soon. They are friends and really need a hand up right now. We'll worry about the other issues another time. (Note: The post I was referring to here was removed.)

              Flames at Reactor 4 no longer visable, hopefully good news.

              Other reactors that have multiple spent fuel rods still rising in temperature.

                Praying for them as well. Wish we could help more.

                I have watched some incredible human interest stories about Japan during this crisis and how they deal as a nation. What incredible courage and selfless-patience this Nation has.

                The reactor problem was a combination of old age and water damage. Ironically the seawater may be their only hope to finally kill these things then it is on to the next problem. This will take years before we as a World are ever the same, then do we ever remain the same?

                      I listened to an economist today who suggests the financial impact will be lower than the Kobe quake. The predicted death tolls are higher than Kobe.

                      The challenge just now is logistics not helped by the nuke mess. They are such a proud people, you just know no mater what they will clear up and get on with it.

                        every self-serving fat cat that made bank convincing the public how safe and bullet-proof nuclear power plants are should be stripped of all wealth, all of their money going to the relief effort. let's put it to a vote, a lot of americans involved in those designs.

                          Those particular plants were designed by GE engineers around 40 years ago. There were engineers that raised concerns about that generation of plants and eventually GE conceded there were improvements that needed to be made. Good design, just like good security, is a journey, not a destination. As you learn more and study the issues you evolve and implement better and safer ideas. GE retrofitted the plants to beef them up and offered to do the same for the plants in Japan. I'm not going to get involved in a discussion about the safety and necessity of nuclear power on a keyboard & synth based board. I'd love to see the creative energy of the world spent working the problem first and worry about blame and finger-pointing later. Emotions are too high to start making huge decisions and running for the torches and pitchforks.

                            not me- stakes are waaay to high for a 40-year wait & see operation. worst case scenario has a power plant thousands of miles away effecting my health.

                              You have a pretty steep uphill climb to ban nuclear plants if that's what you are suggesting. Good luck with that. Here's a map to help you get started.

                              http://www.nrc.gov/info-finder/reactor/

                              I live not far from one and my fear that it may kill me are at the same intensity as my fear of a plane falling into my living room. As someone else stated, the Japanese were hit by a massive earthquake followed by a huge wall of water. That's tough to plan for and engineer against. I believe the people of Japan did and are still doing the best they can to handle the situation. I'm not prepared, nor arrogant enough, to tell a friend that has been a responsible member on the world stage for as long as most of us have been alive what kinds of power sources they are allowed to use.

                              Your posts have been helpful to me and I really respect you for your contribution here, but this is one subject where I'm on a different path than you.

                                Why worry about that when PG&E has found plenty of other ways of killing us much closer to home. Of course PG&E does always have Diablo Canyon if they want to irradiate the whole state.
