A Little Earthquake

Work a few minutes ago was interrupted by a little earthquake. The floor seemed to rumble like a bomb had gone off, then my whole floor (I'm on floor 5 of 8 in my building) started moving back and forth a few centimeters. It was pretty cool. Popping my head out of my cubicle, some people were headed for the stairs to leave, but a little shaking isn't going to get me out of here -- I've got too much work to do to be chased off by a little earthquake.

A whole slew of aftershocks followed a few minutes later. Good to get some of that tension out ... ;)
