Earthquake

So apparently last night around 2AM there was a Level 4 Earthquake in Los Angeles that not only rattled and shook my building but was large enough to knock objects off shelves in home and stores. The reason I say 'apparently' is because I managed to sleep through it! My roommates felt it as did several of my friends who were awake at that hour, but I was fast asleep and didn't even wake up. As far as I've heard, there were fortunately no injuries.
