The Renewable Energy Reality Check

[Benton D Struckcheon]

41. You're not getting it

There's a reason it's spooky & scary: it's undefined. If you can't define the risk you can't mitigate it.
The flaw is in the sentence "once every 1,500 years". That may be the overall rate of some random event, but random events don't sit there with their hands folded waiting for 1,500 years just because some probability model says so. They tend to cluster because, well, they're random.
Secondly, the thing you're not getting is that an undefined risk is just that. You have no idea, and neither does anyone else, when the next one will happen or how many people it will affect or how large an area will be rendered uninhabitable when it does.
The general public's fear may look irrational to you but it's not. Your response is that of a typical utopianist. The real world doesn't fit neat probability models in much the same way the real world doesn't fit the good/evil worldviews of Christians waiting for the end of days or Marxists waiting for the revolution.
