The meeting is intended to be of interest to scientists who study any aspect of Hawaiian or similar volcanoes (for example, Etna, Piton de la Fournaise, Iceland, Galapagos, etc.). In particular, the conference should be of special interest to geoscientists who study mantle geochemistry/physics/dynamics; mantle plumes and hotspots; magma ascent, storage and transport; ocean island evolution; and volcanic eruptions and degassing.
