My children have hardly experienced any earthquakes and we live in Southern California. A far cry from me experiencing some of the larger quakes to hit our area, one of which threw me out of bed pre-dawn and had our power out for some time. My parents experienced some large quakes as well, and some of the family of a previous generation experienced the large Alaska quake that lasted several minutes.

10 seconds is huge, but I'm afraid for a generation that has no concept of what a quake even is at this point. They haven't seen the ground shake or roll, literally looking like it's breathing.
