Subduction zones are responsible for the most-damaging and tsunami-generating great earthquakes. Deep earthquakes occur in the oceanic crust that is being bent downward into the subsurface.

^ "Okataina: Eruptive History". Landslides and Rockfalls Groundshaking due to earthquakes destabilises cliffs and steep slopes, causing landslides and rockfalls as a significant side-effect. Mauna Kea measured from the seafloor to its peak is the tallest mountain on Earth. Significant amounts of metals in association with hydrothermal fluids and magmatic gases are known to discharge from subaerial geothermal systems of the Taupo Volcanic Zone, New Zealand, and active volcanoes such as White Island , .

The Pacific Ring of Fire is aptly named.

Volcanology of New Zealand is the scientific study of volcanoes and volcanic phenomena in New Zealand. Map of the SW Pacific showing features associated with the Eocene–early Miocene subduction boundary adapted from Schellart, location of the Waitemata Basin (W) in New Zealand, and present‐day physiographic features.

Such variations demonstrate that hydrothermal fluids discharging along the southern Kermadec arc are complex products with multiple sources and/or processes at work. Taupo volcano, comprising several calderas (collapsed volcanoes) makes up the northern part of the lake. This is an east–west cross-section of the central North Island, passing though Lake Taupō and Taranaki (Mt Egmont). Learn vocabulary, terms, and more with flashcards, games, and other study tools. Intra-oceanic subduction-related hydrothermal venting, Kermadec volcanic arc, New Zealand. The Mariana Trench is the deepest point on Earth and a prime example of a deep subduction zone. This lesson will discuss the meaning of the term 'subduction zone,' and where they occur in terms of tectonic plate boundaries.

There are 2 main types of subduction zones: Oceanic-oceanic plate boundaries: If the subducting plate subducts beneath an adjacent oceanic plate, anisland arc is formed. The island nation sits . Most New Zealand volcanism in the last 1.6 million years has occurred in the Taupo Volcanic Zone (TVZ). ... A curving line of volcanoes formed where two oceanic plates collide is a(n) _____. Examples of island arcs are New Zealand and _____ In a subduction zone, an oceanic plate submerges into the mantle under a continental plate. The surrounding lighter-coloured region is the area most thickly covered by the deposits of Taupo eruption 1800 years ago. atop an active subduction zone where the Pacific Plate slips below the Australian Plate. New Zealand is the site of one of the world's youngest subduction zones, where the Pacific Plate of Earth's crust dives beneath the Australian Plate. As one plate descends under another plate, it heats up and becomes magma. A typical example of this type of volcano is Mount Etna on the east coast of Italy. Examples include the Aleutians, the Kuriles, Japan, and the Philippines, all located at the northern and western borders of the Pacific plate.

As the Pacific Plate descends, heating causes fluids to rise into the overlying mantle, producing magma.

To the north of New Zealand and beneath the eastern North Island, the thin, dense, Pacific plate moves down beneath the thicker, lighter Australian plate in a process known as subduction. Other articles where Subduction volcano is discussed: volcano: Subduction volcanoes: As an oceanic plate is subducted beneath a continental plate, seafloor sediments rich in water and carbon dioxide are carried beneath the overriding plate. But these examples are unusual, as other volcanoes are mixtures of these extremes.
