Dear Colleagues,

Please consider submitting an abstract to our interdisciplinary volcano
seismology, acoustics, and hydroacoustics session:

*Observations of Volcanism in the Three Spheres: Land, Air and Sea*

Volcanoes are naturally situated at the intersection of the solid Earth
with the air and/or sea. As a result, we can probe the volcanic system
using a diverse range of observable waves: seismic, infrasonic and
hydroacoustic. While these waves can undergo conversions and move between
spheres, information is typically lost in the conversion process and is
best analyzed in the sphere where the source originates. Thus, observations
in the different spheres may be necessary to fully characterize and
understand volcanic activity.

Recent advances have been made using combinations of these observables in
complementary ways to improve our understanding of volcanoes in eruption
and repose. Monitoring networks are increasingly using infrasound to detect
explosions, lahars and other subaerial activity. Underwater cabled
networks, such as that at Axial Seamount and other instrumentation are
opening new possibilities for monitoring and studying submarine volcanism.
Additionally, new seismic technologies, such as large-N arrays, are
allowing for more thorough seismic studies. New or improved methods—such as
machine learning techniques—for processing, analyzing and combining the
variety of data collected from volcanoes are also needed to improve our
understanding of volcanism. In this session, we encourage interdisciplinary
studies but also welcome new studies that showcase the diversity of
advances in volcano seismology within a single sphere. Topics may include
scientific studies as well as work focusing on techniques and
