Since this just happened, I may as well post about it. A medium-small earthquake just rolled through ten minutes ago and the epicenter was about eight miles from my house. It was initially rated a 4.3 but got downgraded to a 4.1. Magnitude 4.1 does not sound like much, but it is pretty large if the epicenter is close. Here is the USGS site and map:

Having lived in California for close to forty years, I have been through many earthquakes, the most famous being the 1994 Northridge earthquake. That was 400x larger than the M4.1 just now, but realeased about 8,000x more energy.
A picture fell over on a shelf in the room I was in. I need to go cheek the house in case anything else fell over or off the wall.
