CA's a big place. Much of it, e.g. the Central Valley, seldom if ever feels quakes. That's probably true of much of the Sierras and Cascades. I've lived in Silicon valley for 32 years and in CA for almost 50; I've probably felt between 5 and 10 quakes (I can only remember 3 or 4). Of those, 1, that of October, 1989, did significant damage. While some died in a freeway collapse and some homes in SF's Marina district were seriously damaged, the vast majority of Bay Area people experienced perhaps 12-24 hours' power outage and some had to detour around the freeway section that had to be rebuilt. People die every year from extreme snowstorms and tornadoes; buildings collapse every year from extreme snowstorms; every year, tornadoes destroy large swaths in towns. My in-laws in KS live a good part of every year "guarding" the weather channel for tornado warnings, and several months a year worrying of ice storms and "black ice" on roads. The SF Bay Area is peaceful by comparison (other than the fruits and nuts in the orchards of Santa Cruz, SF, Berserkeley, Oakland and Marin. But they aren't a natural phenomenon.
