Volcano Processes, Monitoring, and Hazards

Volcano Processes, Monitoring, and Hazards

Session ID#: 248866

Session Description:

Volcanic eruptions result from complex processes which lead to different eruptive scenarios, each associated with distinct hazards such as lava flows, pyroclastic density currents, lahars, ash clouds, and volcanic bombs. Monitoring volcanic activity is essential for both understanding ongoing processes and assessing potential hazards. By combining observational data, numerical simulations, and experiments, we can better understand eruptive dynamics and improve risk mitigation strategies. This session aims to bring together studies that deepen our understanding of the complex processes driving volcanic eruptions through the integration of multi-parameter monitoring techniques, advanced modeling approaches, and experiments. We welcome contributions that utilize seismic, geodetic, thermal, geochemical, and remote sensing observations, as well as those employing numerical simulations or experiments to investigate the mechanisms of magma ascent and eruption dynamics. Emphasis is placed on the synergistic use of these approaches to enhance eruption forecasting capabilities and inform effective volcanic hazard assessment and mitigation strategies.
