The Taupo Volcanic Zone (TVZ) of New Zealand is characterised by extensive volcanism
and by high rates of magma production. Associated with this volcanism are numerous high …

To investigate the underlying magmatic systems that drive high-temperature geothermal
fields and volcanism in the north-central Taupo Volcanic Zone (TVZ), we use a combination …

Hydrothermal systems develop secondary mineral assemblages due to rock and fluid
interactions. Such minerals can be identified on the surface and mapped using …

Magnetotelluric data were recorded in a 45× 10 km band crossing the Rotorua and
Waimangu geothermal fields in the northern part of the Taupo Volcanic Zone in the central …

Abstract The Taupo Volcanic Zone (TVZ) hosts 23 geothermal fields, seven of which are
currently utilised for power generation. Ngatamariki geothermal field (NGF) is one of the …

The c. 15 km-long Ngapouri-Rotomahana Fault (NRF) is a major splay of the Paeroa Fault at
the eastern margin of the modern Taupō Rift, the active tectonic structure embedded within …

We investigate the geological and hydrothermal setting at Lake Rotomahana, using recently
collected potential-field data, integrated with pre-existing regional gravity and aeromagnetic …

Magnetotelluric (MT) data from 169 locations covering a 700 km 2 region in the southeastern
part of the Taupo Volcanic Zone, New Zealand, are used to generate a 3-D resistivity …

Hydrothermal eruptions are characterised by violent explosions ejecting steam, water, mud,
and rock. They pose a risk to tourism and the operation of power plants in geothermal areas …

Inferno Crater Lake, Waimangu, one of the largest hot springs in New Zealand, displays
vigorous cyclic behavior in lake level and temperature. It provides a natural small‐scale …
