Taupo

Kaldera · New Zealand · 760 m

Lake Taupo fills a roughly 35-km-wide caldera that is the site of the most prolific rhyolitic volcano of the Taupo volcanic zone. The caldera was formed during two major explosive eruptions, the Oruanui eruption, roughly 22,600 years ago, and the Taupo eruption, about 1,800 years ago. The latter was one of the world's largest Holocene eruptions. Additional Plinian eruptions during the Holocene have produced widespread airfall pumice deposits.

Taupo, the most active rhyolitic volcano of the Taupo volcanic zone, is a large, roughly 35-km-wide caldera with poorly defined margins. It is a type example of an "inverse volcano" that slopes inward towards the most recent vent location. The caldera, now filled by Lake Taupo, largely formed as a result of the voluminous eruption of the Oruanui Tephra about 22,600 years before present (BP). This was the largest known eruption at Taupo, producing about 1,170 km3 of tephra. This eruption was preceded during the late Pleistocene by the eruption of a large number of rhyolitic lava domes north of Lake Taupo. Large explosive eruptions have occurred frequently during the Holocene from many vents within Lake Taupo and near its margins. The most recent major eruption took place about 1,800 years BP from at least three vents along a NE-SW-trending fissure centered on the Horomotangi Reefs. This extremely violent eruption was New Zealand's largest during the Holocene and produced the thin but widespread phreatoplinian Taupo Ignimbrite, which covered 20,000 km2 of North Island.
