Do the bullet train and hyperloop involve traveling over the ground at incredibly high speeds across major fault zones?
On the plus side, if you’re traveling in the train/hyperloop when the temblor hits, it’ll be over quick!
I’m not worried about being in the tube when the quake hits. The faster people are moving, the less likely they are to be in the tube at the exact moment the quake hits.
The bigger concern with the fault lines is that the tube must be straight, and correcting for plate movement would be much harder than with conventional rail. I might think that a minor amount of slippage could knock service out for a long time.
