An illustration of the Ōruanui eruption 25,500 years ago. The magma expelled from this supervolcano creates a
depression where the magma once was, the volcano collapses, thus making the
crater. This crater is then filled in with water over time, creating a crater lake: this is the geographic history of Lake Taupō.
