I live in Northern Virginia. We have had a few earthquakes over the past several years. I always thought there was a rolling or swaying movement. But it's more like a boom and a shake. Why is this?

The sensation of an earthquake is not necessarily a swaying or rolling motion. Often the sensation is one of a shock or "boom".
