Anchorage, 1964

Nine of the ten of the US’ largest quakes were in Alaska, most near the Alaska Subduction Zone – where the Pacific plate moves under the North American Plate.

The biggest quake occurred in 1964 – 9.2 magnitude. The tsunami from the quake was powerful enough to drive a 2×6 piece of lumber through a truck tire.

This school was completely destroyed.

    I though the Cascadia one was down in the Pacific Northwest?
    But on the bright side, at least they do not have to worry about hurricanes, right? 😉

    On the topic of earthquakes, does anyone have a clue as to why, over the past year or so, Central Oklahoma has been having several minor quakes? We have been averaging about one a week or so with swarms a couple of time a year. I haven’t been able to dig up a single fact explaining them.

    Thanks and Cheers,
    Dan

    I have a cousin who lived in Anchorage for the 1964 quake. I understand that it qualified as “interesting”.

    Oklahoma?
    Probably subsidence quakes from pumping out the oil over the last 100 years.
