    Wow – I live in Raleigh, NC and was sitting in my living room when the house began to shake back and forth. Although I am over 60 and never felt anything like that before, I knew it was an earthquake. Fortunately there was no damage and I got the dog back after he ran outside. I saw in one report that there have been no larger quakes east of the Appalachians since 1970 but I wonder if any larger ones have been recorded in the eastern US?
