The magnitude is essentially useless for measuring the intensity that *you* felt during a particular earthquake. The Japanese do use magnitude but they also use a system that tells you the power of that earthquake where you are on a scale of 1 to 6+. Anyway read about it here http://en.wikipedia.org/wiki/Japan_Meteorological_Agency_seismic_intensity_scaleHopefully he likes quakes that are low level where no one gets hurt.
Here in So Cal we do tend to get complacent about them since we have so many of them. We haven't had a really BIG quake in a long time and I think that sometimes we forget how deadly a quake can be.
The Whittier quake was a bit scary, being kinda close to the epicenter in Rosemead. I remember jumping on my bike and riding around town seeing broken glass everywhere and houses with collapsed porches, and chimneys.
I am certainly glad I wasn't close to the epicenter of the Northridge Quake in 94. I sure felt that one.
Far more relevant scale imo.
We had one here in 2001 that I felt as 5+ (6.8 magnitude)....the most unpleasant 20 or so seconds of my life.
