5.6 on the richter scale

I woke up and my bed was shaking.  All I could think about was 'oh now what, another bed story?'  The last few nights have been memorable.  Bed bugs.  Then the next night man with my undies on.  Tonight, well less than an hour ago I wake up to my bed shaking.  No noises.  I look around my room no one is in here.  Then I contemplate ghosts.  But it last too long.  Earthquake?  Do I get up and run to a doorway?  I grew up in tornado country, not shaky land.

Attempted to close my eyes again after it ended.  Riiiight.  You think I can sleep after that?  Failed attempt.  When I looked at my ipod it said 4:53a.m.  Instead of sleeping I ran a series of events through my head that could have been the reason for my bed shaking.

After researching seismic activity, this is what I found from the quake at 4:52am:
