I have lived in California a long time. I have also lived in both hurricane and tornado country.
IMO, earthquakes and wild fires are not as large a threat as seasonal hurricanes, tornadoes, etc. Every place has its own set of risks. You get used to them. Most people, the vast majority, are never directly affected by any of them.
What does matter is when a risk, a potential threat, becomes YOUR reality. If the earthquake is right under your house, if the wildfire is in your back yard or at your Club's range, only THEN is it a BIG deal. For most, that never occurs.
For most, a wild fire is a disruption in traffic as you commute to work (or can't get there). For most, an major earthquake damages their freeway route to work and they have to adapt.
This is analogous to hurricanes and tornadoes, except hurricanes and tornadoes happen multiple times every year. IMO, they're a much bigger risk.
If you have a great job offer at Beale, I'd say TAKE IT! Plan ahead for the cost of living and housing but if those are in line, take the job.
