While I was setting up this site late last night, I felt like something was wrong. I heard my wardrobe make aching noises, and the ground started moving. First slightly, then more and more. At the end, it felt like our house was swaying from side to side with an amplitude of at least a few centimeters. Pretty scary stuff. Turns out the source of this was an earthquake whose epicenter was actually quite a ways from Karlsruhe.
