Last Thursday morning, an earthquake hit the Bay Area at 4:30 in the morning.  It was a magnitude 4.3 and epicenter was just across the bay in Oakland.  The strong shaking and loud rumble actually woke us up.  I was still very groggy but it still registered in my mind as an earthquake.  Sara said "It's an earthquake!" and I sleepily replied "it's okay, nothing will happen" and we promptly fell back asleep.  On my drive to work the next morning, the radio shows were flooded with callers saying things like "the earthquake this morning really shook me up, I'm staying home today."  Those kinds of comments were weird, since I didn't think too much of the earthquake.  Does that mean I'm now acclimated to quakes, or maybe I was just too sleepy to really feel the full strength of the quake.

I think it may be more the former.  My office is on the 4th floor of a four storey building located just off the highway, and a couple times a week there's a soft rumble and vibration.  I'd always thought it was nothing more than a big truck passing by on the highway or even some movers inside the building dropping a piece of furniture, but then I found out from corworkers that the rumbles are indeed earthquakes.  I was actually thinking my coworkers were pulling my leg - the ol' "Let's scare the newbie and tell him these are earthquakes" - but then we had this happen to one of the main conference rooms in my office:

Glass-shattering quakes

The window actually shattered from a quake!  That means I've been experiencing earthquakes all along!  They're so weak as to not even register as an earthquake, though, so I'm not considering them as earthquake experiences - that means I've been through two earthquakes so far and both of them have been harmless.  Hopefully my future earthquake experiences stay harmless.
