It is not. It is forced up through the Earths mantel and then through the volcano. The volcano itself is just solidified magma (called lava as it exudes from the volcano).

Is magma a explosive eruption and why?
Magma is not an eruption. Magma is a mixture of molten minerals and dissolved gas that is underground. All volcanic eruptions, apart from phreatic eruptions, involve magma.
What signs can scientist study to try to predict volcanic eruptions?
Before an eruption, magma moves into the area beneath the volcano and collects in a magma chamber, or reservoir. As it comes closer to the surface, the magma releases gases. These events can offer valuable clues about the likelihood of an eruption.

How does magma composition and the resulting eruption affect the form of a volcano?
If the composition of the magma is high in silica, the eruption will be explosive. The Eruption of Mt. St. Helens was an explosive eruption. If the composition of the magma is low in silica, it will produce a quiet eruption. The eruption(s) of Mt. Kilauea are quiet eruptions.
Lava is magma that has reached the what in an eruption?
Lava is magma that has reached the surface of the earth in an eruption. When this cools down, it will form igneous rocks.
What comes out first magma or lava?
magma is lava that has not been exposed to the air before eruption.
How does magma chamber differ from a vent?
A Magma Chamber is a space (that can change size) at a depth below a volcano in which magma can accumulate prior to an eruption. A volcanic vent is a conduit connecting the magma chamber to the surface. It is though this that the magma flows during an eruption.
What causes small earthquakes before a volcanic eruption?
The earthquakes are caused by the movement of magma underground and the breaking of rocks by that magma.
What are the crystal structures in porphyritic rocks?
They're called phenocrysts, allowed to slowly cool in magma before eruption of the magma.
What about magma affects how explosive an eruption will be?
The composition of the magma affects how explosive a volcanic eruption will be.
Is molten rock called lava before it erupts?
No, it is called magma before eruption and lava afterwards.
What happens before a volcanic eruption?
magma falls from underground to form an opening in the volcano
How is strength of a volcano eruption related to the magma in the volcano?
If the magma is more viscous, the eruption is stronger.
