Not really. But when they do happen, they travel far due to the granite underground that transfers the vibration. The "DC" earthquake was actually centered some miles away in VA, but was felt from the Carolinas up thru New England...
Think of it like hitting an iron bar. Not much movement in the rigid bar, but you can feel the vibration all along the bar...
As opposed to the CA earthquakes, which are much more centered with lots of ground motion, causing much more damage...
