5.4 magnitude earthquake

I was at my cube when it shook the building and around 11:45am. It was pretty scary and I’m sure I wouldn’t know what to do because I just sat there and looked up. Got that image from www.usgs.org which keeps track of earthquakes here in California. I haven’t felt one this strong in a while. At first, I thought someone was jumping up and down but after realizing that there isn’t anyone that large here at work.. it had to be an earthquake. My co-worker thought it was the same. Near our desks we have a weak section on the floor where, if someone were to jump, you could really feel it. Luckily, nothing big came after that but there were numerous aftershocks after the big one. Please, Earth, do not scare me during my lunch. kthxbai.
