Topic:
Global population growth and connectivity have increased the vulnerability and awareness of natural hazards. Destructive earthquakes occurred in the past, including the recent Sumatra 2004 or the Sichuan 2008 events, and have lead to very high economical and human losses. Major volcanic eruptions, such as the Etna 2002 or the Chaiten 2008 events, affected population, disturbed air traffic and resulted in economic loss across the borders. These events once more demonstrated the far reaching and often indirect effects associated with dynamic shaking, site amplification, explosivity and ash transportation, tsunami generation and associated processes, and the need to investigate underlying processes and monitor time dependent activity states. This session aims to serve as a general and special platform to exchange novel techniques, results and understanding related to hazards in association with earthquakes and volcano activity. In particular it encourages, but is not limited to, studies related to:

• the physics of earthquake and volcanic eruptions
• triggers, occurrence and associated hazards
• long-term and short-term deformation and structural evolution
• field and modelling methods to investigate earthquake ground shaking and volcano eruption processes and associated effects
• relationships between earthquakes, volcanoes and their environment - evolution, migration and intrusion of magmas
• hazard assessment and risk reduction in earthquake and volcanic regions as well as general topics related to earthquake and volcano research.
