As a result the Magnitude 5.9 earthquake that occurred today in Virginia was felt in at least 22 states plus the District of Colombia. Ground shaking has been reported to the USGS and by news accounts in: New Jersey, New York, Pennsylvania, Delaware, Maryland, Virginia, West Virginia, North Carolina, South Carolina, Tennessee, Kentucky, Ohio, Massachusetts, Rhode Island, Connecticut , Vermont, New Hampshire, Maine, Indiana, Georgia, Florida and Washington, DC.
