Underwater volcanoes are formed when the floor of the ocean cracks and tears apart. This exposes the underlying mantle and lava starts to flow out. In time, and after enough lava has flowed, these volcanoes will become islands.
And also,a volcano works because lots of heat comes up&then it pushes all the magnum up
the earths magma is hotter than the water but there is so much water that the evaporation re condensates mostly into the water, magma being pushed up by the movement of tectonic plates allowing passages to build pressure and break the earth surface

They erupt with a force greater than hundreds, sometimes thousands of atomic bombs.
Water is hardly a problem.
