Can you survive a tsunami in a submarine?
Submarines are relatively unaffected by weather or tsunamis when submerged in deep open waters. Once a submarine is deep enough the conditions on the surface are not felt. However if a submarine has to go shallow or to periscope depth then conditions on the surface become a major concern.
Is it hot inside a submarine?

How long can an average submarine stay under water?
Submarines generally stock a 90-day supply of food, so they can spend three months underwater. The diesel-powered submarines (not now used by the United States Navy) had a limit of several days submerged. They couldn’t run the air-breathing engines while fully submerged and had to rely on battery power and electric motors when underwater.
What is the longest time a nuclear sub has submerged?
Longest time submerged……. HMS Triumph sailed to Australia in 1993, travelling 41,000 miles submerged without support — the longest solo deployment so far by a nuclear submarine. Can anyone tell me how long this took?
How long can a nuclear sub stay underwater?
