it breaks down
During the more violent eruptions, pieces of the rim of the volcano can break away, changing the shape of the volcano.
Composite cone volcanoes containing high amounts of silica with a gas content of four to six percent in highly viscous magma can become superheated. The gases expand a thousandfold and can blow whole portions of the cone away with other pyroclastic materials.
It becomes a liquid, loosing its consistent shape.
It changes shape and volume.
it becomes smaller
The orbit becomes more eccentric until the orbit becomes almost a strait line.
It becomes denatured which means it changes its shape. Enzymes that change their shape do not function properly anymore.
The type of volcano was a cone volcano because it has a big cone shape at the top of it.

The parabola shape is magnified. If you keep the same scale for the graph, the parabola will look wider, more flattened out.
