Dr. Kilgour started out at GNS Science as a geothermal geologist, working for almost 10 years on the largest development of geothermal energy in New Zealand. He then started working on the phreatic eruption of Mt. Ruapehu (NZ) in 2007, examining the mechanisms and energy of the eruption and the lahars that followed. He subsequently gained his PhD at the University of Bristol on the reservoir and ascent conditions of magmas preceding small volume eruptions at Ruapehu. Current work focusses on the magmatic processes, with specific reference to volatiles and their exchange during magma mixing, responsible for generating basaltic and rhyolitic Plinian eruptions. But his real passion is trying to unravel the timescales and providing forecasting tools for small, phreatic and small volume magmatic events.
White Island is New Zealand’s most frequently active volcano and activity have been noted for more than 100 years. A rather puzzling aspect of its recent eruptions is that the volume of ejecta in each event has been remarkably small (
