And he was on hand to adjudge it safe. I was thinking more of when 
buildings fall over (as happened in the quake I mentioned, but that was 
Tammin, quite a small place). At least one building in Perth did crack 
and the crack was visible from the street.

If there's nobody on had to decide it's safe, I would rather no volts. 
B'sides, if there's serious building damage, who cares about the average 
server?
