Deep Earth tremors may foretell major earthquakes | The Extinction Protocol: 2012 and beyond: "December 29, 2012 – SEATTLE - Tiny tremors, smaller than earthquakes, are shaking the Cascadia subduction zone deep beneath the Pacific Northwest. The Cascadia subduction zone is where two of Earth’s tectonic plates meet in an epic collision and one haltingly slides below the other. The Cascadia Fault stretches for almost 700 miles (1,100 kilometers) from Northern California up to Canada."
