The Earth's axis is always the same in relation to the Universe. The Sun has a pull on the Earth and may have more of a pull on the magma when the volcano is facing the Sun.
The volcano's distance to the equator may make a difference in the rate of eruption and explosiveness of the eruption as there is more centripetal force propelling the magma at the equator than at the pole.
The prime meridian really has nothing to do with the erupting of volcanoes except that certain places on Earth are more likely to have faults in the crust, which is the cause of volcanoes.
The equator and the Greenwich meridian.
The equator, and the prime meridian.
The angular distance north or south of the earths equator, measured in degrees, along a meridian, as on the map or globe.
The two hemispheres are not separated by any physical barrier. The equator on maps/globes mark the separation.It's called the equator.And it's not a meridian, meridians (such as the prime meridian) deal with the earths lines of longitude, aka west to east.The units dividing the earth north to south are the lines of latitude, zero being the equator.
It depends on which one. The one that goes from pole to pole is the Prime Meridian. The one that goes the other way is the Equator.
The two main imaginary lines on Earth are the Equator, which divides the Earth into the Northern and Southern Hemispheres, and the Prime Meridian, which divides the Earth into the Eastern and Western Hemispheres.

A Meridian or Meridian Line is an imaginary line drawn between two points. In geography these two points are an imaginary arc on the earths surface from the North to the South Poles. In astronomy it is an imaginary circle in a perpendicular plane to those planes of the celestial equator and horizon.
Celestial Equator
Every line of longitude north of the Equator is a baseline that runs on the Earth's surface to the North Pole. Prime here is the Prime Meridian -- 0 degrees.
Volcanoes are created by the movement of tectonic plates on the Earth's surface. When two tectonic plates collide or move apart, magma from the mantle rises to the surface, eventually erupting through a volcano. Additionally, hotspots, subduction zones, and rift zones can also contribute to the formation of volcanoes.
The eastern and western hemispheres are separated by a single continuous line which passes through the geographical north and south poles. On the one side of the earth, it is the 0, or Greenwich, Meridian and, on the other (Pacific) side, it is the 180 meridian (which should not be confused with the International Date Line - though this approximates to the 180 meridian, it zig-zags across it repeatedly, at the behest of political convenience).
