Cf. Captain_Swoop's links to ships being struck by various ordnance, including -- at the end -- a Mk 48 naval torpedo. You are correct in that a substantial detonation is required to heave the ship. Also, torpedoes are designed to swim under the keel of the ship and detonate there, thus causing such heave and breaking the keel. The combination of explosive charge and charge placement is required.
Also, such detonations are evinced in seismographs. No such detonations were recorded that night.
I am a bit surprised that explosions near the surface of the ocean would show up on seismographs. Surely, it would have to be a pretty large explosion? Or am I just wet?
