PhD Research

My research is focussed on the past 1000 year of eruptive activity of Mt. Taranaki, New Zealand. At least nine eruptive events are known to have occurred in this time. The dominant eruptive style at Mt. Taranaki is the emplacement and destruction of lava domes generating hazardous block-and-ash flows with only one sub-Plinian eruption having occurred in this period. The transition from an effusive to explosive eruptive style is the main subject of my studies. Applied analytical techniques comprise XRF, EMPA, He-pycnometry, porometer, FTIR.
