    Caldera volcanoes are violent eruptions that throw magma, ash and rock across large areas. After the eruption, the volcano collapses into the space left by the empty magma chamber, forming a very large crater.

    In this model, the balloon represents the magma chamber. The hole that is formed represents the crater.

    Note that the video does not have a soundtrack.
