fissure
The opening that you are asking about is called a vent. Magma can burst through any weakness in the side of a Volcano or underground passage where Magma is close to the surface. There are also openings called Tubes that are sometimes formed that Magma flows through that are like channels and the Lava stays very hot and flows very fast through them to the end where it comes out very fluid.
Magma becomes lava after reaching a volcano's vent.Volcanoes have a pocket beneath the surface called a magma chamber. The magma moves upward through a pipe, witch is a long tube that connects the magma chamber to the surface.Molten rocks and gas through it's opening called a vent.It's all written here in a text book called Prentice Hall Earth Science. This information is at page 210.
Magma reaches the Earth's surface through a process called volcanic eruption. This occurs when pressure builds up underground and forces the magma to flow and eventually break through the Earth's surface. Once the magma reaches the surface, it is then called lava.
A vent through which gas, ash, and magma erupt onto Earth's surface is called a volcano.
The tunnel that magma goes through to reach the top of a volcano is called a conduit. This conduit is often a vertical pipe-like structure that connects the magma chamber beneath the volcano to the surface.

Once magma breaks through the earths crust it is called"lava"

the magma gets to hot it bursts under the sea forming island

Mountain chains formed by magma coming through rift zones are called volcanic mountain chains or volcanic arcs.
The term for the flow of magma through cracks in the Earth's surface is called volcanic eruption. During an eruption, magma is forced through fissures or vents onto the surface, leading to the formation of volcanic features like lava flows, ash clouds, and pyroclastic flows.
These pipelike structures within a volcano are called magma conduits. They are formed when molten magma rises from a magma chamber towards the surface. Conduits can vary in size and shape, and they play a crucial role in allowing the movement of magma, gases, and volcanic materials during an eruption.
Before lava reaches the surface it is called magma.
