Thanks. That helps put it into a time perspective. However, the entire West Coast is over-due for "the big one". This is a super quake bigger than anything experienced since the area was inhabited by Europeans. The San Andreas Fault is just a pesky little crack compared to the Cascadia Subduction Zone (CSZ) which was not discovered until recently. Over the last 10,000 years, the CSZ has "gone off" only 41 times, generally producing the largest kind of earthquakes known, those exceeding 9.0. That's an average interval of 243 years. The problem being, the last time it happened was 1699-1700, over 320 years ago. And longer intervals of quiet can lead to more powerful quakes. These are the type of land movement that can cause entire coastal cities to end up underwater and one event can basically deconstruct the entire coast. And, yes, it's more than 75 years "overdue". Which is quite a bit considering the average interval is 243 years.
Without straying too far into the weeds, let's just say that having your sole manufacturing plant lose power, water, sewer, natural gas and access to public roads (that can be driven on) for many months or even longer than a year is something to factor into the risk equation. I was very concerned about this over the last several years but now that Tesla production has diversified to China (and soon into Germany) it is becoming less of a major risk and more of a potential "thorn in the side". Still a major potential disruption, but survivable in a way that it would not be if Tesla was a one-trick pony.
In other words, those of us with quake concerns are not looking to the 1940's or 1950's as our measuring stick, we are looking at a timescale that pre-dates European settlement. In fact, this risk was unknown in the 1950's.
