I live on a 6th floor of an apartment building in S.D. and was awaken by my fiancee putting the death grip around me.
Had no idea what was happening until a few seconds later I hear the concrete walls and ceiling creaking and making wierd noises.
I'm from Florida so these quakes are definitely a wake up call.
The last earthquake (4.? on the RS) was a lot scarier for me since I was actually awake for the whole thing. Just thanking my lucky stars that this building is in S.D. and not on the north coast... not sure it wouldve came out unscathed.
Anyone all of a sudden scared to death of the concrete ceilings???

I miss trusses... LOL
