Many smaller eruptions, primarily of dacite and lower silica rhyolite, occurred in between the two large eruptions. It is a type example of an "inverse volcano" that slopes inward towards the most recent vent location. The mega-eruption began on February 2nd, when a … Such a giant eruption would have regional effects such as falling ash and short-term (years to decades) changes to global climate. Radiocarbon dating indicates an uneven spacing of Taupo's eruptions, from decades to thousands of years apart. The Taupo eruption was the most violent eruption in the world in the last 5,000 years; it was a complex series of events. Those parts of the surrounding states of Montana, Idaho, and Wyoming that are closest to Yellowstone would be affected by pyroclastic flows, while … The Plinian eruption column probably would have been 50 km high, which collapsed to produce pyroclastic flows.

The Taupo Eruption 1800 years ago The most recent eruption of Taupo was about 1800 years ago. To put that into context, Krakatoa’s eruption in 1883 was VEI-6 and Mt St Helens in 1981 was VEI-5 This eruption is of interest for several reasons: (a) It was one of the largest explosive eruptions in the world within the past 7000 years; New Zealand’s Taupo Volcanic Zone hosts the most frequent recent rhyolitic eruptions than anywhere else in the world, all active in the last 2 million years. The large proposed volume of the Kaharoa tephra requires confirmation. In New Zealand, the Taupō caldera system shares many similarities with Yellowstone—a history of large eruptions, geysers and hot springs, and even earthquake swarms and ground deformation, some of which might be related to magmatic … Pictured here in New Zealand’s Tongariro National Park, is Mount Ruapehu, one of the most active volcanoes in the world. The VEI 8 eruption with the greatest volume of ejecta known is the Wah Wah Springs eruption that occurred in what is now the state of Utah, about 30 million years ago.
