There is moisture above ground too and ground movement can affect the poles as well. I would think that there is more exposure to damages above ground with cars hitting them, tree limbs, strong winds, animals chewing through wires, etc. While it’s easier to repair damages above ground I believe there would be less of them with buried lines.
