| that's a big earthquake. i didnt feel anything, but i am pretty far south. |

| Yeah the warning area was out in the alleutians....so for anyone in ...even mainland alaska, let alone anywhere on the west coast to feel it would have been a fluke....there is a lot of country up there. |

| I heard nothing of it on the news here. Although I believe Alaska usually has alot of earthquakes. Most of them aren't too major, but 7.5 is definitely a strong one. I guess an earthquake in Alaska is like a volcano spewing in Hawaii...they just don't report it on the news very often. |

either that or it's just cause of how few people live there. |

Yeah but that shouldn't matter. Like the second an earthquake hits (no matter what magnitude) somewhere like California or an urban community every news broadcast is interrupted. |
