Overview

Taranaki image
Taranaki

Taranaki has a long history of volcanism as well as cone building collapse over the past 200kyr. Detailed tephra sequences have revealed patterns of cyclicity in the eruption record over the past 30,000 years. The magmatic plumbing system controls on these patterns have as yet not been clearly defined.

This project statistically investigates petrographic and chemical changes within the eruptive record (from single eruption to eruptive periods) to understand the dynamic conditions of magma storage and evolution and reveal the sequence of processes that may lead to different eruption styles.

The study is done in collaboration with Professor Shane Cronin (University of Auckland) and Associate Professor Ting Wang (Otago, Department of Mathematics and Statistics).
