That depends on the depth. I can't remember the exact depth, but once you reach a certain depth, pressure is so immense that that just won't happen
- the lava will actually continue to move, without cooling for quite a while, the pressure is so enormous that gases will not escape. Think of it as
a state of equilibrium.
Anyways, Lava is spewing out of the ocean depths all the time, and you don't see these "BOOMs" that you are talking about. If the lava vent is
close to the the surface, all you really get is a bunch of continous steam and a bunch of hot water. There are underwater explosions, but not on the
scale you are thinking. Most of the big problems in the ocean are earthquakes and landslides - those we must be worried about, because they can cause
tsunamis. :-D
