Mel, you don't sound like a doomcryer, nor like a conspiracy theorist.
But I will hasten to assure you, as I've been watching this map for, literally, more than 10 years, that it's not as bad as it might look. I've seen it far more "red" than it is now. And, to be honest, I'd prefer to see more "red" right now because I want the pressure which I suspect is enormous right now be released a bit at a time...
There are certain areas which are always lit up, sure...the Salton sea to the south, San Fran and surrounding to the north, and a big one in the last month off of Eureka, at the border of OR/CA. But it's nothing unusual, it really isn't.
Still, as I've said before, it's a worry that most of the Pacific Rim has had large magnitude quakes recently (last 6 months), but we have not...and that is a concern to me.
Time to check emergency equipment and supplies, but I don't think it's time to be terribly worried. Just cautious.
Best-
