Is it possible for subway tunnels to collapse?

This has been on my mind since Sandy. As we know the tunnels/equipment were it possible that the structures have weakened and could collapse? Would the East River flood the stations if that happened? What about the Brooklyn Battery Tunnel/Holland Tunnel/etc, can they just cave in? Would you drown?

The amount of damage that would have to be done in order to get a tunnel to collapse would be so extensive, it is very unlikely you or anyone would even be in the tunnel in the first place.

And I'm talking about the tunnels that go from borough to borough (i.e. Brooklyn to Manhattan)

What about the N train on the Manhattan bridge? I'm always afraid that something will happen to the track and the train will be sent careening into the river.

if the tunnel floods for some time, yes

How about an earthquake? There must be a point on the Richter Scale that would rupture a tunnel, but perhaps there is nothing that could damage them enough for water to enter, just have some mud?

Are they rated on a once in a thousand year quake, or once in ten thousand?

Sure it is. Anything's possible OP.

I wonder that myself if there is an earthquake--not only that but all those dams in Tennessee built by the TVA in the 1930s make me wonder too about collapse should there be an earthquake like the one in 1811 in that same general area. I understand in that one the Mississippi River flowed backwards for certain amount of time. The thing is, then there were relatively few people in that area since it was then considered frontier. One can't begin to imagine the disaster to this countryand the world if an earthquake like that should happen again.

It's an interesting quake, and projecting the damage should a similar quake occur today just mind-boggling...

They are not tunnels. They are actually tubes.

Isn't the Boston Big Dig dropping concrete and springing leaks?
