Davide Bonadonna is an Italian volcanologist and researcher specializing in the study of volcanic ash dynamics, tephra dispersal, and eruption forecasting. He has held academic and research positions at several European institutions, notably serving as a professor of volcanology at the Institute of Earth Sciences, University of Geneva, and as a senior researcher at the Swiss Federal Institute of Technology Zurich (ETH Zürich). Bonadonna’s work focuses on quantitative modeling of volcanic ash transport, the development of probabilistic hazard assessments, and the integration of field observations with numerical simulations to improve predictions of volcanic impacts on aviation, public health, and climate.
Education and Career
Bonadonna obtained his doctoral degree in Earth Sciences from an Italian university (specific institution and year not publicly documented). Following his Ph.D., he pursued post‑doctoral research in volcanology, during which he contributed to seminal studies on tephra particle size distributions and plume dynamics. He later joined the University of Geneva, where he leads research projects on volcanic ash hazards and collaborates with international agencies, including the International Civil Aviation Organization (ICAO) and the European Commission’s research programs.
Research Contributions
Bonadonna is widely cited for his contributions to the quantitative description of volcanic ash fallout. His publications include studies on the effect of particle size distribution on tephra dispersal, the development of probabilistic ash cloud forecasting tools, and the assessment of volcanic eruption impacts on air traffic. He is a co‑author of the textbook Volcanic Ash: Hazard, Dispersion and Impacts (Springer, 2020), which synthesizes contemporary knowledge on ash generation, transport, and mitigation strategies.
Professional Activities
Bonadonna participates in interdisciplinary consortia aimed at improving volcanic risk mitigation. He has served on scientific advisory panels for the European Space Agency’s satellite monitoring of volcanic eruptions and contributes to the development of operational ash forecasting systems used by aviation authorities. He is also involved in training programs for emergency responders and public communication of volcanic hazards.
