Julia is a volcanologist specialising in explosive volcanic eruptions and associated hazards. Her main interests lie in volcanic hazards and impacts of volcanic eruptions on all scales, from local communities to national and global. Julia’s recent research focuses on the implications of volcanic hazards on international tourists; physical vulnerability of buildings to tephra fall and the impacts following multi-hazard events. Julia’s background is in geological mapping, specifically using volcanic stratigraphy, tephrochronology and the petrology of eruption deposits to understand past behaviour and potential future behaviour. Her research includes volcanic hazard analyses in Ethiopia, Ascension Island and Mexico using a scenario-based approach and expert elicitation to determine frequency, magnitude and likelihoods of potential future eruptions.
