Resource assessment and reserve estimation play a crucial role in the decision-making,
financing, development, and operation of geothermal projects. The present study critically …

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 …

Abstract The nature of Yellowstone National Park's plumbing system linking deep thermal
fluids to its legendary thermal features is virtually unknown. The prevailing concepts of …

The Taupo volcanic centre lies at the southern end of the Taupo Volcanic Zone in the central
North Island of New Zealand. Major rhyolitic eruptions of 400 and 35 km3 (dense rock …

During 2002 and 2003, carbon dioxide fluxes were measured across the Rotorua
geothermal system in the Taupo Volcanic Zone (TVZ), New Zealand. The results of a 956 …

Within the installation of a shallow geothermal system, the lack of information on the subsoil
frequently leads to errors in the design of the geothermal wellfield. This research presents …

Hydrothermally altered rocks, particularly if water saturated, can weaken stratovolcanoes,
thereby increasing the potential for catastrophic sector collapses that can lead to far …

The Rotorua geothermal field is a shallow geothermal reservoir lying directly beneath
Rotorua Township in New Zealand. Temperatures of up to 200° C have been recorded at …

An integrated geophysical study consisting of magnetic, very low frequency (VLF)
electromagnetic and electrical resistivity tomography (ERT) surveys has been carried out in …

Electrical resistivity measurements have been used to investigate a 650 km 2 region
containing four separate areas of geothermal surface activity: Waimangu, Waiotapu, Waikite …
