The Taupo eruption of 232 AD was one of the most violent volcanic events in the past 5,000 years, and the caldera it left behind is now Lake Taupo, the largest lake in New Zealand. This is the North Island Volcanic Plateau, also called the Central Plateau, and it is currently the most frequently active and productive area of silicic volcanism anywhere on Earth. Three active volcanic peaks anchor its southern end. A supervolcanic caldera fills its centre. Two of New Zealand's longest rivers begin here. It is a landscape that is still, quite literally, being made.

At its heart lies the Taupo Volcanic Zone, a rift system where the Pacific Plate is being subducted beneath the Australian Plate. Extensive ignimbrite sheets, the hardened remains of pyroclastic flows, spread east...

The Waikato, the country's longest river, begins its journey from the northern end of Lake Taupo, flowing north through the Waikato basin to the Tasman Sea. The Whanganui rises on the wester...

Mount Pihanga, north of Tongariro, sits at the centre of a love story in which the mountains themselves are characters: Tongariro, Taranaki, and Pihanga are bound in a legend of...

North Island Volcanic Plateau: Living on an Active Landscape

People ski on Ruapehu's slopes, fish for trout in the Tongariro River, and mountain bike through the forests that cling to its margins. The Raurimu Spiral, a railway engineering marvel, climbs 122 metres in just 1.6 kilometres through tunnels an...
