Do you hear them...or are they just alot of rolling and shaking?
I have never heard them. However when I used to live in Sunnyvale, I would hear the sound of glass moving back and forth in the windows. maybe that is the sound, I don't know. I always thought that was the effect of the earthquake and not the quake itself.
Depends...I remember in the early 80's here in the Inland Empire...what sounded like a freight train coming toward my house. Seconds later an earthquake hit. In '92 the Landers/Big Bear quake came from the same area and it too had that same sound although not as pronounced, but the quake was much greater. Most quakes don't give you that kind of warning. This one today, I didn't feel at all as I was driving. Rats. Nothing like a good earthquake to liven up the day.
