Hmm, I thought there was a much larger one in 2001 or 2002. I remember my cabinets rattled a bit and I lived on the first floor at the time.

I was in Pasadena for two decent quakes, one of which was the Northridge quake (1994). I remember thinking a train was going by until I realized that I didn’t live near any trains. We were studying elastodynamics in Kip Thorne’s class so that made it passably interesting, if a bit geeky—you know when you have an aftershock at lunch and think to yourself, oh so there is a difference in speed between the two waves. (Bonus points for timing that difference as a way of measuring the distance from the epicenter.)
