Caldera Volcanoes of the Taupo Volcanic Zone, New Zealand
The Taupo volcanic zone (TVZ) has been active since 2 Ma and has erupted >104 km3 of dominantly rhyolitic magma during the last 1 m.y. Most of the volcanism is concentrated in a 125×60 km area
Growth of a young, frequently active composite cone: Ngauruhoe volcano, New Zealand
Abstract.Ngauruhoe cone, in southern Taupo Volcanic Zone, New Zealand, has grown rapidly over the last 2,500 years in an alternation of effusive, strombolian, vulcanian, and sub-plinian eruptions of
Vulcanian eruption mechanisms
Application of a newly developed theory to volcanological observations of explosive eruptions shows that previous estimates of pre-explosion gas pressures may be overestimated by an order of
Geological setting of the 1987 Edgecumbe earthquake, New Zealand
Abstract The 1987 March M L 6. 3 Edgecumbe earthquake occurred at shallow depth within the Whakatane Graben at the northeastern end of the onshore Taupo Volcanic Zone. The graben has formed where the
The 1976–1982 Strombolian and phreatomagmatic eruptions of White Island, New Zealand: eruptive and depositional mechanisms at a ‘wet’ volcano
White Island is an active andesitic-dacitic composite volcano surrounded by sea, yet isolated from sea water by chemically sealed zones that confine a long-lived acidic hydrothermal system, within a
Growth of the Tongariro volcanic complex: New evidence from K-Ar age determinations
Abstract New K‐Ar age determinations indicate that the exposed portion of the Tongariro volcanic complex has grown steadily since at least 275 ka, with intervals of vigorous cone growth at 210–200,
Millennial timescale resolution of rhyolite magma recharge at Tarawera volcano: insights from quartz chemistry and melt inclusions
Most rhyolite eruption episodes of Tarawera volcano have emitted several physiochemically distinct magma batches (∼1–10 km3). These episodes were separated on a millennial timescale. The magma
