This session focuses on the transport and chemical evolution of erupted materials during and after volcanic eruptions, and includes studies of both short-term (hours-years) and long-term (decades and longer) eruption impacts on Earth’s atmosphere, oceans, ice sheets, and land. We welcome studies that employ field, remote-sensing, laboratory, and numerical modelling approaches, and particularly encourage interdisciplinary submissions.

Studies may focus on any aspect of transport from the magma system, through the conduit, and into the atmosphere, ocean, and along the ground during effusive, explosive and hybrid eruptions. This includes processes that physically and chemically modify erupted solid, liquid, and gas phases during transport and deposition. We are particularly interested in studies that 1) investigate the evolution of multiphase physical transport and chemical alteration processes and 2) explore the implications for hazards and environmental impacts during and after eruptions.
