Well, I am awake now. A 4.1 earthquake is not much as these things go, but when it is a few miles due east of the house, it does get your attention http://earthquake.usgs.gov/earthquakes/recenteqsus/Quakes/nc71336726.php So I jumped out of my chair to get out from under my A/V receiver which sits smack over my computer. About the time I got to the hall, it quit shaking. I looked out the back window to see Fritz the cat twisted in a quarter turn, glaring into the house at me. It was, of course, my fault, as are all the loud human disturbances to his quiet universe. Nothing seems to have fallen, although I did hear stuff moving during the shaking. After inventorying all of the various cracks, we see the concrete next to the side of the house has moved another 1/2"away from the foundation, there are several new cracks, and all the existing ones are now bigger. But the important stuff, the retaining walls, all look to be the same as before. Yay!
