Our biggest volcano isn't a cone. It's Lake Taupō, formed about 25500 years ago in the massive Ōruanui eruption.

The Taupō supervolcano system was created by subduction of the Pacific Plate below the Australian Plate. The movement of plates stretches the Earth's crust.

The bottom visible unit is an exposure of an unwelded pyroclastic flow deposit from the Oruanui eruption, which formed Taupo's initial caldera about 22,600 ...

Lake Taupō was formed about 26,500 years ago by the massive Ōruanui eruption. This threw out 1,000 times more pumice and ash than Mt St Helens (United States) ...

Caldera volcanoes are created by collapse of the ground surface due to emptying of their sponge- like magma chambers in huge eruptions - which.

Oruanui was so explosive that its ejecta was deposited away from the vent, collapsing the ground over its emptied magma chamber to form a caldera.

The Lake Taupō caldera was created by an eruption 27,000 years ago called the Oruanui Eruption. Since then there have been at least 26 much smaller eruptions.
