Yes. Japan engineers tunnels -- one longer than the Chunnel -- to survive 9+ earthquakes and they do. BART was undamaged by the Loma Prieta quake that brought down the Bay Bridge and the Oakland freeway.
- CamperBob2 11y agoThe length of the tunnel doesn't have much to do with earthquake survivability, beyond the obvious linear scale factor. What the tunnel is tunneling through has a lot to do with it. Seattle's geology is somewhat different from any of the usual cited examples, as we've learned by watching everyone from journalists to politicians to engineers stand around with dumbfounded looks while the Bertha saga unfolds.
