All earthquakes are products of the dynamic planet we live on. They typically occur as massive slabs of the Earth's crust, called tectonic plates, bump against, over and past each other.
But the East Coast isn’t anywhere near a plate boundary. So what causes the earthquakes we feel in Appalachia? A seismologist at the University of North Carolina thinks he might know. A team led by Dr. Berk Biryol examined the patterns of seismic waves passing through the North American continent, and discovered it appears parts of the crust under our feet are slowly falling away and sinking deeper into the Earth. Biryol talks about his findings with Method host Brandon Hollingsworth.
