Earthquake?!

According to all the people around me we just felt a quake in the building. Now the fire safety emergency director is calling out in the speaker system saying that nothing is going on and that we are probably ok. The problem here is that I did not feel it! I just stood up from my chair as all the other people started asking what just happened. I feel so left out: finally an earth quake and I did not even register it. Remains to hear what it was, should I call Uppsala?
