- dredmorbius 7y agoEarthquake-induced ground movements tend to be in limited areas immediately adjacent to faults, unless the effects are cause by induced land movements (e.g., landslides) elsewhere. An above-ground fault-crossing, with slace sufficient for maximum predicted ground movements (generally on the order of 5m or less) should generally address that.
- marcyb5st 7y agoThat sounds like and excuse. I'm Italian and back at home we also have heartquakes and wildfires problems. And yet a lot of our distribution lines are underground (apart from the high and ultra high voltage ones).
- djrogers 7y agoIt's the high and ultra-high voltage lines taht are the problem here. A lot of in-town power lines are buried in California, but those aren't the lines that are under scrutiny here.
