Is Lake Taupo a caldera?
In Māori mythology Tia discovered the lake. Taupo is a ‘supervolcano’ and one of the most frequently active and productive rhyolite caldera in the world. The huge caldera (collapse crater) has been partly filled by New Zealand’s largest lake, Lake Taupo.
Is there a volcano under Lake Taupo?
Taupo volcano last erupted over 1,800 years ago and is today filled by New Zealand’s largest lake. Lake Taupo fills the large caldera volcano. Taupo volcano first began to erupt over 300,000 years ago. It is very large and has many vents, most of which are now under Lake Taupo.
How big is the Taupo caldera?
roughly 35-km-wide
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.
What’s the deepest lake in NZ?
Lake Hauroko
Kayakers paddle on a calm Lake Hauroko, at 462 metres New Zealand’s deepest lake, in the southern part of Fiordland National Park.
Is New Zealand a supervolcano?
New Zealand has the world’s most frequently active supervolcano system! The central Taupō Volcanic Zone (TVZ) has two recently active volcanic centres, Taupō and Okataina. Every few decades the TVZ experiences unrest and every few hundred years it erupts.
What happens if Taupo erupts?
“If Taupo were to erupt, we would expect to see major ground deformation and thousands of earthquakes, not hundreds,” Jolly says. White Island’s 2000 eruption followed a long period of activity and is one of “a couple” of eruptions Jolly has seen.
How did the Taupo caldera form?
The huge caldera (collapse crater) has been partly filled by New Zealand’s largest lake, Lake Taupo. The caldera is created by subsidence of the ground surface due to emptying of the magma chamber in huge eruptions.
What type of volcano is Lake Taupō?
Unsourced material may be challenged and removed. Lake Taupō, in the centre of New Zealand ’s North Island, is the caldera of a large rhyolitic supervolcano called the Taupō Volcano. This huge volcano has produced two of the world’s most violent eruptions in geologically recent times.
How many vents does the Taupo Volcano have?
The Taupō eruption’s three main vents ran parallel to Lake Taupō’s current southeastern shore. The Taupo eruption (also known as the Hatepe eruption) represents the most recent major eruption of the Taupō Volcano, and occurred about 1,800 years ago.
What happens in the Taupō Volcanic Zone?
Hot magma rises and feeds a long chain of volcanoes. The Earth’s crust is unusually thin in the Taupō Volcanic Zone. Magma gets close to the surface – and sometimes breaks through. Every now and then, huge eruptions leave giant holes in the landscape. The volume of erupted material was 8–9 times the volume of water in Lake Taupō today.
