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)]

"Where other people had debated whether or not it [the tear] was there, we can pretty confidently say that it's real," study lead researcher William Hawley, a doctoral student in the Earth and Planetary Science Department at the University of California, Berkeley, told Live Science.

1. Cool, and thank you for posting that.

I am fascinated by all things tectonic and geological.

5. Thanks for taking the time, last lib.

"I Feel the Earth Mover Under My Feet" wouldn't have been as memorable!

7. Thank you for this and your other Science articles.

I pay attention to the Pacific NW. I have two nieces and their famlies in the Portland area.
