Thesis Title
Small-volume volcanism associated with polygenetic volcanoes, Taupo Volcanic Zone, New Zealand
Read article at Massey Research Online: 
The Taupo Volcanic Zone was the world’s most productive silicic volcanic region over the past 0.5 million years. Besides the dozen large-volume caldera-forming eruptions, more than three hundred smaller-volume eruptions have been recognised, usually producing pyroclastic deposits and lava domes. With the aim of understanding the volcanic hazard posed by future small-volume eruptions in the central North Island of New Zealand, Mr Kósik researched the physical volcanology and geomorphology of three case study sites in different environmental settings with eruptions that are characterised by diverse eruption styles and chemical compositions. In addition, the spatial, temporal and volumetric patterns of small-volume eruptions of the entire Taupo Volcanic Zone were examined using Geographical Information Systems (GIS). Mr Kósik's research results contribute to understanding the evolution of the volcanism of the Taupo Volcanic Zone, as well as the creation of better policies for hazard assessment and mitigation for future volcanic events.
