Awww you are a nice wall! What happen when you smile? Does the building shake?

I smile when when I have visitors; except when you tell me sad things. Glad you asked if the building shakes.  Yes, and we measure it objectively.  Down on Level One in O’Neill, check out our live seismograph (bit.ly/OneillShakes)! I am guessing the 2 bursts of interesting activity between 8 and 9 UTC this morning were due to the two Mag 5.9 earthquakes off the coast of Oregon, though, not my smiles…
