I remember an earthquake in Maine in late 1981. I was up late, and I felt our house shudder slightly, as if it had settled a little more than usual. --It turned out that it was an earthquake that measured about Richter 6 a bit further downeast from Portland, where I was at the time.
I also remember in 1998 when I was living in Charlotte, NC. I heard a loud distant rumbling like thunder early one clear April morning. --It turnd out to be an earthquake of about the same strength epicentered near Greenville, SC. --I didn't feel anything from that one, though.
