Japan is slowly burying all their overhead lines into the sidewalks. A lot of urban streets look so much nicer now than they did 10 years ago.
It’s probably no worse in an earthquake than the water mains, which would inherently be a lot more rigid than cables with intentional slack built into every segment.
Afaik, the problem with buried cables is that in case of a flood or tsunami they might break, get exposed and electrocute someone.
Is that less likely to happen if the pole is knocked down instead of the line dug up?
No idea, that's what I've been told, but Japanese engineers usually know what they are doing.
I know that a downed power line is very visible, especially if it's live and touching water! I wonder if it's underground if you might miss the signs
