About COT and IAVCEI
International Association of Volcanology and Chemistry of the Earth’s Interior was founded in 1919, originally as the International Association of Volcanology (IAV).
IAVCEI focuses on research of volcanology and mitigation of volcanic disasters. Scientists also participate in IAVCEI research in closely related disciplines, such as igneous geochemistry and petrology, geochronology, volcanogenic mineral deposits, and the physics of the generation and ascent of magmas in the upper mantle and crust.
