The workshop aims to bring together experts in selected fields of geophysics and physical volcanology, qualified graduate students, and early career scientists to discuss oscillatory source processes in volcanic fluids and plumes. There are two primary objectives for the FOVSys II Workshop. The first is to bring more cohesion to the fields of volcano geophysics and physical volcanology. The second aim is to take the original orkshop topic, escalate the eruptive intensity, and consider processes closer to the vent and aloft. The conveners propose to address the increasingly available geophysical data sets for Vulcanian to Plinian eruptions, and consider how researchers can use these data in the fields of explosive volcanism, physical volcanology, eruption prediction, and hazard forecasting.
Outcomes for NSF FOVSys II There were two primary objectives for the Second Fluid Oscillations in Volcanic Systems (FOVSys II) Workshop. The first is to continue the FOVSys I workshop's aim to bring more cohesion to the fields of volcano geophysics, explosive volcanism, and physical volcanology. The second aim was to take the original workshop topic, escalate the eruptive intensity, and consider processes closer to the vent and aloft. The primary audience for this workshop was graduate students, postodcs, and early career scientists, which were strongly represented. Of the total 36 participants, 14 were Ph.D. students, 7 were postdocs, and 5 were early career faculty, totaling 26. Of these participants, 22 graduate students, postdocs, and early career faculty in US institutions were supported by this grant. The geophysical and physical volcanology communities may study the same volcanic processes, but often speak in a different language. This is partly due to different measurement timescales. Most geophysical fluctuations in volcanological interest have timescales of fractions of a second to hundreds of seconds, whereas many physical volcanologists specialize on geological records (millennia) or at best on timescales of years. With the increase in multidisciplinary research, there is a need to bridge this gap. The workshop promoted a closer interaction between the geophysical and physical volcanology communities, which should help facilitate basic research collaborations. This workshop also filled a pressing need to educate the next generation of volcanologists on the interdisciplinary methods available to understand complex, unsteady eruptive processes, and how to interact with colleagues in complementary disciplines. The relatively small size (36 participants) and workshop format promoted interaction between students, earlier career scientists, and specialized experts Workshop participants were exposed to a very diverse range of subjects spanning from geological to geophysical studies of Hawaiian to Plinian eruptions. The workshop format left abundant time for questions and discussion after the lectures, as well as during the communal breakfast, lunch, and dinner. A unique, active infrasound source was set up at the conference venue and incorporated as part of Dr. Garces' presentation, providing the audience a rare immersion in a fully developed, carefully controlled reverberant infrasound field. H. Gonnerman, B. Houghton, B. Chouet, M. Garces, and A. Clarke were all invited speakers to the workshop, and the material they presented was published in the text "Modeling Volcanic Processes". This knowledge will make a lasting impact on future generations of volcanologists through courses that use this textbook as a reference. References: The Physics and Mathematics of Volcanism, 2013.
