You're welcome, La Enchiladita. While not surprising I don't think I'll ever get used to being jolted awake to the sound of flying books, furniture and walking refrigerators. Just something about it is unsettling. ;)
One thing I remember re Northridge was that first it was a SOUND, a rumble, and THEN it shook. It was such a deep rumble.... oooohhh, I’m scaring myself remembering:-(
