The process chart is representing the developing of a super volcano in nine stages. The beginning of formation starts from appearing the magma chamber inside the crust which causes high pressure building in the crust that create the volcano eruption. The final stage is the crater formation because of land depression.
The magma chamber expends in sizes due high temperature as it goes straight from the hot mantle. Also this creates extra pressure in the crust and force the magma find a way out to release high presser. In addition, this event involves deep surface structural changes, such as fissures developing, which expend the surface and push the magma out of the chamber. This transformation led to massive smoke and lava exit from the surface. More fissures make the formation goes faster.
However, after the eruption initial chamber is down size. When, land from the surface depress in to the crust empty space, filling the chamber and create super volcano crater. Also this change significantly surface landscape and dangerous for infrastructure.
