    We Could Be Witnessing the Death of a Tectonic Plate, Says Earth Scientist

    A gaping hole in a dying tectonic plate beneath the ocean along the West Coast of the United States may be wreaking havoc at Earth's surface, but not in a way most people might expect.

    This gash is so big it may trigger earthquakes off the coast of Northern California and could explain why central Oregon has volcanoes, a new study found.

    The researchers in the new study aren't the first to suggest that the Michigan-size Juan de Fuca (pronounced "wahn de fyoo-kuh") plate has a tear. But thanks to a new, detailed dataset, they're the first to say so with certainty. [The Science of Plate Tectonics and Continental Drift (Infographic)]

  • Interesting stuff...Does any of this have a potential impact on the possibility of "The Big One" occurring in the PacNW?

    The article doesn't address that directly, but it seems pretty likely it would be related. I believe the Pacific Plate is moving more or less Northwest, while the North American Plate is moving generally westward, so this small plate is kind of in an interesting location.
