The tunnel is called a lava tube or magma tube.
It's called a conduit.

Vents in the volcano are passage ways for the magma, steam, and heat to escape the earth.
The channel through which magma rises within a volcano is called the "magma conduit" or "volcanic conduit." This passage allows magma to move from the magma chamber beneath the Earth's surface to the surface, where it can erupt as lava. The size and shape of the conduit can influence the type and intensity of volcanic eruptions.
The part of a volcano that connects the vent with the magma chamber is called the "conduit" or "volcanic conduit." This cylindrical passage allows magma to travel from the magma chamber, located beneath the surface, up to the vent, where it can erupt. The conduit plays a crucial role in determining the characteristics of volcanic eruptions.
The channel that magma uses to travel toward the vent in a volcano is called a "conduit." It is a narrow passage within the volcano that allows molten rock to move from the magma chamber to the surface during an eruption.
A Magma Conduit is hot fluid or semi-fluid material within the earth's crust from which lava and other igneous rock is formed by cooling.

The order of parts through which magma reaches the surface of a volcano is the magma chamber where it accumulates, followed by the central vent or conduit where it travels upwards, and finally the crater or vent at the surface where it erupts and flows out as lava.
It was the middle leg of the triangular trade route that Europeans followed.
The amount of viscosity present in magma depends on the amount of silica it has. A composite volcano produces rhyolitic lava which is very thick. A shield volcano produces a basaltic lava with less silica and significantly less viscosity.
