Groundwater that comes in contact with magma or rocks heated by magma can boil into steam. If it boils quickly enough it can result in an explosion called a phreatic eruption.
The matter thrown out of a volcano while it is erupting is called lava, and it consists of melted rock matter. Before erupting, the lava moves underground towards the opening of the volcano. When it is underground like this, it is called magma.
A fumarole is a vent on or near a volcano that emits gas. A hot spring is a pool of water heated by an underground source.
Underground water is cleaner.
Deep underground, water can be contained in porous rock formations such as aquifers, which are layers of rock that can hold and transmit water. Another way water can be contained underground is in underground water reservoirs or natural underground chambers created by geologic processes like caves or caverns.
An aquifer is an underground accumulation of water.
A geyser is an underground volcano with water on the surface of it. This water is then boiled by the magma.
Water is heated by an underground volcano and boils.
subterranean
Yes, water vapor can come out of a volcano along with other gases and volcanic materials during an eruption. Additionally, some volcanoes have crater lakes that can release water during eruptions or due to interactions with magma underground.

Lava, which is melted solids from the underground

Underground water is called underground water, because it is "underground" not because it is fresh or salt. You can have underground salt water reservoirs just like you can have fresh water ones.
No mines. But there is an underground chamber in Arturus. And the volcano passages are underground. (see related questions)
The underground pressure inside of the volcano built up and finally exploded. It was looking for a pathway with the least resistance and the volcano's central lava tube was it.
Underground water is cleaner.
It could have been an underground volcano and then a rift formed and it erupted and rose above sea level.
