More than 75% of the volcanic activity on Earth occurs underwater. Recent unrest observed at many submarine volcanoes raises serious concerns regarding the level of risk posed to local communities. Many parameters of submarine to emergent volcanic activity are under active investigation, including how explosive activity varies with water depth, magma properties and magma composition. This session brings together experts from diverse disciplines to explore hazards posed to island and coastal communities as well as mechanisms of submarine to emergent volcanic activity.

The session will include presentations that integrate innovative and emerging technologies to enable focused and multi-disciplinary studies of recent and ancient eruptions and their products, as well as breakthrough developments in understanding the impact of disastrous submarine volcanic hazards on present and past societies.

We call for abstracts in the following areas:
- Identification of submarine volcanic hazards such as explosive eruptions, volcanic earthquakes, submarine landslides, hydrothermal emissions and volcanogenic tsunamis.
- Studies of the mechanics of submarine and emergent volcanic eruptions and formation of oceanic islands.
- Investigations of optimal monitoring technologies and state of the art methods that provide new insights into explorations of submarine volcanoes, which host hydrothermal systems, mineral deposits and biomediated processes.
- Recommendations for volcanic crisis management, public awareness and preparedness through an improved understanding of the hazards and impacts of submarine volcanoes.
