I wonder why they haven’t gone underground there.

Also most of the wildfires around here get started by lighting strikes, so I can only assume that occurs there as well.

Short answer: It’s really expensive. It can be worth it in a densely populated area where you have a few dozen feet of underground wire per household. But when you are burying tens or hundreds of miles of cable for a relatively small number of customers the cost is prohibitive.
