Our son and his wife lived in Temecula, California for a couple of years where he was in charge of one of the most complex robotic manufacturing machines yet invented, which operated to incredibly tiny tolerances. He could never understand why it had been installed in an earthquake zone...
Once when we were staying with them and on holiday with a hire car we went specially to drive across the San Andreas Fault, naively imagining a visible crack that snaked across the landscape. We were very disappointed when we couldn't see anything at all other than a road sign.
I bet it's a lot warmer in California at the moment than in England or the Creuse - though I must admit that today in our bit of Cheshire we are now at +2C - positively tropical.
