It was over in less than a minute. Three miles below the surface of the earth near a town in Virginia called Mineral, a fault line shifted. As a result, a 5.8 magnitude earthquake was felt from Georgia to New England and as far west as Detroit. The National Cathedral lost several stone spires, the Washington Monument cracked, and Sojourners' office was closed for the afternoon, as our building was checked for structural damage.
Tectonic plates move beneath our feet in the part of the globe that scientists refer to as the lithosphere. Over the course of a year, an average plate will move as little as 3 to 6 centimeters. The speed of their movement is 10,000 times slower than the hour hand on a clock and even slower than the rate of growth of human hair. For decades, sometimes centuries or millennia, a plate's movement might go almost entirely unnoticed. Then, in less than a minute, the world shakes and everything changes.
