Lake Taupo [SEP] Lake formation and volcanism
Lake Taupo is in a caldera created by a supervolcanic eruption which occurred approximately 26,500 years ago. According to geological records, the volcano has erupted 28 times in the last 27,000 years. It has ejected mostly rhyolitic lava, although Mount Tauhara formed from dacitic lava. Taupo has been active for 300,000 years with a very large event known as the Oruanui eruption occurring 26,500 years ago. It was the world's largest known eruption over the past 70,000 years, ejecting 1170 cubic kilometres of material and causing several hundred square kilometres of surrounding land to collapse and form the caldera. The caldera later filled with water to form Lake Taupo, eventually overflowing to cause a huge outburst flood.
