The International Association of Volcanology and Chemistry of the Earth's Interior (IAVCEI) is a learned society that focuses on research in volcanology, efforts to mitigate volcanic disasters, and research into 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.

The Executive determines policies for the Association, enacting them through a series of commissions and task groups.

The name was changed to International Association of Volcanology (IAV) at the Fourth General Assembly of the IUGG (Stockholm, 1930).

The medal is given every 4 years to a scientist who has made outstanding contributions to volcanology based primarily upon field observations.
