How does an underwater volcano erupt when it is filled with water in the vent ?

It is interesting that hree-quarters of all volcanic activity on Earth actually occurs underwater.
It is no use as water entering vent would evaporate causing pressure . When magma reaches the level of the seafloor, it meets cold ocean water and quickly cools to form basaltic rock, often termed "pillow lava" due to its rounded shape. This pillow lava, along with slower-cooling magma beneath it, forms the vast majority of oceanic crust.
