King of Prussia PA....Yep

I wear headphones when I work and people have been know to shake my chair to get my attention.  I kept looking around and nobody was there.  We started seeing everyone leave the building so my area did as well.  After about 20 minutes everyone went back inside.  I wonder if someone actually checked something in our building or if people just got tired of standing outside and decided to go back in.

Felt it in NYC.  I thought someone was jumping on the back bumper of my ambulance until I looked up and saw buildings shaking and people rushing out of buildings in to the streets.  NYPD is under a "level one mobilization" due to overcrowding in the streets of lower Manhattan.

Hey LoneLock and CampingPhil-

We felt it too!  DH works in West Chester PA; he was on a rubber roof working on an industrial AC unit when it began to shake; I was sitting in a concrete-slab building (waiting for my tow vehicle to be inspected - I'll use this opportunity to give a shout-out to the excellent folks at Gene's Auto Body on Stout Drive in Warminster!)

I initially thought that a car or something heavy had fallen onto the floor of the auto body shop; I thought I was having a stroke or something and was about to die - the thought of an earthquake never entered my mind.  After my oldest son and sis called/texted me to discuss, I felt much better!

DH was evac'd from QVC; my youngest sis was evac'd from her building in Ft. Washington.  My mom in Roslyn saw crystal prisms on her lamps shake; my mother-in-law five blocks away doing yard work didn't feel a thing. 

I was working.. Shooting practice. 8)  I was better off than my 2 co workers who were 60' in the air on lifts.
