V13D:
Volcano Seismology and Acoustics: Recent Advances in Understanding Volcanic Processes III Posters


Submit an Abstract to this Session


Session ID#: 44116

Session Description:
Volcanic eruptions may involve a variety of hazardous phenomena including ash plumes, gas emissions, explosions, pyroclastic flows, lava flows, and lahars. Mass wasting may also occur during periods of volcanic quiescence. All of these phenomena produce seismic and infrasound signals that may provide key real-time information on hazardous surface phenomena. We can also gain insights into volcanic hazards by tracking subsurface processes such as magma and hydrothermal fluid migration using volcano seismology.

Recent advances in analysis and interpretation of seismic and acoustic data facilitate a precise characterization and quantification of the physical processes leading to and producing hazardous volcanic phenomena. However, volcano seismology and acoustics remains an emerging area of research.

We welcome submissions that explore new seismic and acoustic observations, interpretations, models, instrumentation, or techniques that further our understanding of volcanic processes and potentially aid future monitoring efforts.
