The IAVCEI Commission on Tephra Hazard Modelling (THMC) was born in 2003 to improve our quantitative understanding of tephra hazards using numerical models and field data. Over the past 20 years, the commission has actively organized workshops, symposia, and fostered communication among numerical modelers, field geologists, and operational forecasters from the observatories and volcanic ash advisory centers.
Current leaders of the Commission are Dr Alastair Hodgetts (Univ. of Edinburgh – UK), Dr Paul Jarvis (GNS Science – New Zealand), and Dr Thomas Aubry (Univ. of Exeter – UK).

Alastair is a physical volcanologist and geologist at the University of Edinburgh, UK. His research is focused on the reconstruction of past eruptions and their processes to better understand a volcano(es) history and future hazards. Alastair has experience in field geology, stratigraphy, geochemistry, geochronology, petrology and numerical modelling and has worked in both academic and government environments. Through his research, Alastair aims to better understand explosive volcanism with a goal to gain knowledge that will ultimately save lives.

Paul is a physical volcanologist and fluid dynamicist at GNS Science, New Zealand. His research is focused on developing and testing models for the processes that happen at volcanoes, both beneath the Earth’s surface and above ground before, during and after volcanic eruptions. Previous and current research has used a combination of laboratory experiments, numerical modelling and field observations to address problems ranging from the dynamics of explosive eruption plumes and clouds and the sedimentation of ash through to dynamics of magma mixing.
Dr Thomas Aubry

Thomas is a physical volcanologist and climate scientist at the University of Exeter, UK. His research is focused on the dynamics and dispersion of volcanic plumes, and on interactions between climate and volcanic eruptions. He uses numerical modelling, observations, and laboratory experiments to address his research questions. When not thinking about volcanoes or climate, hiking, kayaking, surfing, and running are some of his favourite activities.
