White Island is New Zealand's most active volcano and primarily characterised by phreatic and phreatomagmatic eruptions. A phreatic eruption on August 2nd, 2012 ended an eleven year quiescence. More than 100 years ofintense hydrothermal activity from magmatic fluids and groundwater has created a...

Constraining conditions for phreatic eruptions and evaluating the influence of hydrothermal alteration on the process: an experimental approach (Vuelco mini conference Barcelona 2013)
20 Mar 2013 | Contributor(s): Klaus Mayer, Betty Scheu
Phreatic eruptions are caused by rapid evaporation of hydrothermal fluids to steam with the resulting pore overpressure leading to fragmentation of overlying rocks.We investigate White Island (New Zealand) and the active volcanic sites Solfatara and Monte Nuovo in Campi Flegrei (Italy); further...

Constraining edifice stability and phreatic eruptions at White Island, New Zealand (CoV 7 2012)
20 Mar 2013 | Contributor(s): Klaus Mayer, Betty Scheu
White Island is New Zealand's most active volcano and is primarily characterised by phreatic and phreatomagmatic eruptions, interspersed by occasional strombolian events. The common occurrence of magma-water interaction at White Island derives from the presence hydrothermal system that induces...
