Over 75% of the volcanic activity on Earth occurs under water. Recent increased unrest at many submarine volcanoes raises serious concerns regarding the level of risk posed to local communities. The overall goal of this session is to promote an integrated volcanological and socio-economic approach to underpin new concepts (e.g. for risk monitoring protocols or civil hazard planning), next-generation commercial products (e.g. for in-situ sensors or imaging instrumentation), and innovative services (e.g. for education/training or early-warning systems for society) for understanding the impact of disastrous submarine volcanic hazards on society.The topics of session should cover, without being limited to, the following areas: i) documentation and identification of submarine volcanic hazards such as: volcanic eruptions and related seismic activity, submarine landslides, hydrothermal emissions and volcanogenic tsunamis using classical field geology, numeric modeling, and analog experiments, ii) exploration of optimal monitoring technologies and state of the art methods, providing new insights for further exploration and potential exploitation of submarine volcanoes,which host significant hydrothermal deposits, minerals and fauna, iii) volcanic crisis management, general public awareness and preparedness, for a better understanding of the hazards and impacts of submarine volcanoes.

This session is under the aegis of the IAVCEI Commission on Submarine Volcanism.
