| Don't know much about plate tectonics but I was wondering would having such a major release of energy on the fault line make it LESS likely for an equally major quake to strike closer to Tokyo with obvious orders of magnitude of greater destruction. |
| Earthquakes, by definition, release pressure. It's kind of like an emergency release valve. So in general an earthquake will make future earthquakes less frequent or less powerful. But I suppose it's possible that some of the earthquake's energy could go into tightning a certain area and making the next earthquake there worse. |

Earthquake predictions: http://www.nextearthquake.com/ Interesting website. |

This site does a better job of graphically breaking down the locations and stress types associated with tectonic plate convergence in the region than anything else I've seen.

Quoted:
The USA would fall into the Atlantic Ocean.
Talked with my Aunt last night that lives in Alaska and she says usually they have a quake after the Japan area does. But that's just based on a personal point. So guess we will see. Wonder what would happen if Kalifornistan moved 8 feet. |

Wonder what would happen if Kalifornistan moved 8 feet. If it happened all at once, you would see similar damage to what we're seeing in Japan. But over even a hundred years, it has moved more than that. Also, the nature of the movement is not the same as the tectonic activity that caused the Japan quake. That quake happened in a convergence zone with a subducting plate. The plate boundry in california (San-Andreas Fault) is a sheer fault where the two plates are rubbing against each other. A good example of the rate of relative motion can be seen in the following image:

well... it did move Japan 8 ft... I also heard today that it also caused the earth to tip 10* on its axis, which will affect the length of a day and seasonal changes until it corrects itself. LOL at Arfcom counterintelligence.

Read an article yesterday that it shifted the earth's axis ~4 inches. 10 degrees is an enormous amount |

Quoted: An "expert" on Fox this morning said that there was almost certain to be at least one 8 magnitude quake and ten magnitude 7 quakes with 2 years of an earthquake this large. So that would mean that they have the 8 coming and nine more 7s coming. They've been having several 5's and 6's lately...  |

So they are saying that its close to 10,000 confirmed dead and estimating as high as 100,000. With nuclear drama thrown in. With more big quakes to come. Wow. Sucks to be Japan right now. |

Quoted:
I think in Japan's case it might depend on which fault moved. They are sitting on three fault lines. This one happened just West of the Okhotsk/Pacific plate boundary. At 24 km deep, that places it in the subducting portion of the PAC plate . They estimate a 150 x 50 mile chunk of plate broke free from the rest of the plate causing the quake. This image shows all the plate boundaries and individual faults in the NKTZ. It's the most active seismic zone on the planet.

Ya 10 degrees would be a rather large shift. It would make eating tacos easier. |
