I was eating lunch in a restaurant in King of Prussia, PA
the whole place was shaking
although it was all over pretty quick, maybe 20 or 30 sec?
but everyone knew or suspected immediately, we were all saying “wow that must have been an earthquake” although it wasn’t violent enough for stuff to fall off tables etc.
I think we are maybe 150 miles northeast of the epicenter??
KYW news (AM radio 1060) was reporting a water main break has closed PA Rte. 23 at Valley Forge National Park
apparently attributed to the quake
