I emailed #1 Son in NYC to see if he felt the earthquake. His reply:
Yeah, we were on the eighth floor of the pediatrics building, and it started swaying back and forth. We all thought of terrorist attacks or some structural problem in the building before we thought of earthquakes. We were in a session where medical students present cases to a friendly attending, and the attending we were with was this very practical (though also very smart) "I'm a mom" sort of pediatrician, and then we just went on with it. But my first year friend told me they were doing CPR training and all had to evacuate the building for no reason, so yeah, Sinai did do its panic routine.
And there you have it.
