If you're referring to the scientific term, magma collects in magma chambers.
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)
A caldera may form inside the crater of a large volcano. A caldera is a large depression caused by the collapse of the summit of the volcano following a massive eruption. It can be several kilometers in diameter.
The material inside the volcano.
Each volcano is different, but some show changes in temperature, the crater may vent more or change shape, earthquakes often happen, cracks form, the area around it may have more steam vents, new mud pots, or gas vents. Some just blow with no warning.
· It is determined by the primary factors of the magma's Temperature, its Composition, and the amount of Dissolved Gases it contains.

No
magma flows up to form the eruption
All volcanoes erupt for the same reason: magma making its way to the surface of the water inside the volcano, where it turns into steam and gas. The steam and gas propels the magma from the volcano, causing the eruption.
"Magma"
Magma chamber.

Not a bomb in the usual sense- lava bombs are globs of lava formed inside of a volcano- blown out by the force of an eruption.
The material inside the volcano.
You have to clear all the other worlds before you can do that.
Each volcano is different, but some show changes in temperature, the crater may vent more or change shape, earthquakes often happen, cracks form, the area around it may have more steam vents, new mud pots, or gas vents. Some just blow with no warning.
To make an easy volcano at home, you can use materials like baking soda, vinegar, dish soap, and a container like a plastic bottle or a mound of dirt. Create a volcano shape around the container, then mix the baking soda and vinegar together inside the container to create a foamy eruption. Adding dish soap can make the eruption more bubbly and realistic.
