  1. Experimental approach to constrain phreatic eruption processes on White Island, New Zealand (IAVCEI 2013 poster presentation)

    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...

  3. Between cyclic eruptions (VUELCO meeting, Barcelona, 2013)

    20 Mar 2013 | Contributor(s):: Fabian Ben Wadsworth

    Volcanic unrest begins with precursory signals which are the detectable manifestation of dynamic subsurface changes. In 1997, Vulcanian eruptions from Soufrière Hills volcano (SHV), Montserrat, had a mean repose time of 9.5 hours and produced remarkably regular precursory signals. Cyclic...

  4. 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...

    I am especially interested in interactions between magma/lava/tephra and ice/snow/water. Most of my field work has been in Iceland, British Columbia, Russia and Alaska, with lesser work in...
