The Local Organising Committee, on behalf of the International Association of Volcanology and Chemistry of the Earth’s Interior, invite the global volcanological community to convene in New Zealand for the IAVCEI 2023 Scientific Assembly. The Scientific Assembly will be held within the Rotorua caldera amongst some of New Zealand’s iconic volcanic landforms and deposits, and in the heart of one of New Zealand’s cultural and touristic centres. We are developing a diverse and inclusive scientific programme involving high profile plenary speakers and broad suite of session themes. Particular attention will be given towards assisting early career researchers to participate in contributing to the conference. A range of exciting and informative scientific field trips will be offered before and after the conference that will show case the world-class volcanic landscapes and deposits that New Zealand and surrounds have to offer. Mid-conference field trips will highlight the volcanic and geothermal geology of the central Taupo Volcanic Zone. The conference will also feature a selection of pre- and post-conference scientific workshops.
