2011 Virginia earthquake East Coast earthquakes, equations that predict ground shaking might need to be revised." In addition to the great landslide distances recorded, the landslides from the 2011 Virginia earthquake occurred in an area 20 times larger than expected from studies of worldwide earthquakes. Scientists plotted the landslide locations that were farthest out and then calculated the area enclosed by those landslides. The observed landslides from the Virginia earthquake enclose an area of about , while previous studies indicated an expected area of about from an earthquake of similar magnitude. It is estimated that approximately one-third of the U.S. population might have
