Every time I see something like this I’m shocked that we can build infrastructure in fault zones at all. What happens if a tunnel passes the a a fault line and an earthquake happens. Some googling suggests they wouldn’t build a tunnel through this large of a fault and for smaller faults the tunnel is designed to safely deform with the ground in an earthquake
You want them to empty San Francisco? In Chicago they tunneled into the lake and flooded it, but you wouldn't say we shouldn't build next to water would you?
Sorry if I gave that impression. I love sf and I currently live there. I just thought it was interesting how infrastructure must be built to handle this. As an aside I believe sf is not built directly on top of a fault line that’s quite this active. There’s are major faults near by so in a major earthquake I think there might be some sheer on tunnels, but nothing like this
It's ok! The bronze age collapse was brought on partially by earthquakes too. Fault lines and waterways are very useful but can be dangerous. I know Japan has lots of earthquakes but they're better prepared. I heard they never sell buildings, only land and if it has a building on it they often demo it to make it safer.
