The field of plate tectonics is not that old, and scientists continue to learn the details of earthquake-producing geologic faults. The Cascadia Subduction Zone - the eerily quiet offshore fault that threatens to unleash a magnitude-9 earthquake in the Pacific Northwest - still holds many mysteries. A study led by the University of Washington discovered seeps of warm, chemically distinct l
