A Magma Reservoir is a Magma Chamber so to speak.
It is an underground cavity containing molten rock, esp. below a volcano.

Magma chamber? Or the lithosphere or a mantle plume, depending on where the volcano is.
Under the Earth's crust. When it surfaces it is called Lava
Lava collects inside a Magma Chamber. "When an erupting volcano empties a shallow-level magma chamber, the edifice of the volcano may collapse into the voided reservoir, thus forming a steep, bowl-shaped depression called a caldera" (Quoted from How Volcanoes Work at http:/wwwzperiodzgeologyzperiodzsdsuzperiodzedu/how_volcanoes_work/Calderaszperiodzhtml)
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.

Micro seismicity, an increase or change in the chemical composition of volcanic gasses and potentially deformation or bulging of the Earth's surface may all be evidence of magma being fed into a volcanic reservoir.
The force of a volcanic eruption is affected by many factors. They include, viscosity of the magma, its temperature, amount of gas content, and the size of the magma reservoir.
A volcano magma chamber is a large underground reservoir that holds molten rock (magma). It is a key component of a volcano's plumbing system and acts as a storage unit for magma before it is eventually erupted to the surface. The magma chamber is typically located beneath the volcano and can vary in size and shape.

Factors that determine the force of an eruption are magma viscosity and gas content.
Well, the magma reservoir or chamber beneath every volcano gets it's fuel from the Earth's mantle (a layer of seething magma). So every time a volcano erupts, emptying or lowering the level of magma in the chamber, some magma from the mantle will rise (over time) to fill the gap.
A magma chamber in a volcano is a pool-like container of liquid rock just below the earth underground. It is constantly under tremendous pressure, and with enough time, it can start fracturing rock to make places for magma to escape.
No. The continents 'float' on a huge reservoir of magma - melted rock - and the deep underground/undersea forces push the continents slowly but unstoppably around on the surface of the globe.
