Understanding volcanic hazards and their mitigation is a central challenge in geoscience. Volcanoes impact human societies and the environment on regional to global scales, yet they remain among the most complex and least accessible systems on Earth. Knowledge of their plumbing systems, eruptive histories, and the frequency or magnitude of eruptions and collapse events is still limited. Traditionally, insights were derived primarily from petrological studies and the restricted exposures of volcanic edifices.
In recent years, seismic imaging has emerged as a powerful tool to investigate volcanic systems, providing constraints on plumbing structures, eruptive products, and associated mass-wasting processes across a wide range of spatial and temporal scales. Advances in seismic tomography enable imaging of magmatic systems from crustal mush zones to shallow, melt-rich reservoirs. Meanwhile, high-resolution reflection seismic methods reveal the shallow architecture of volcanoes, including internal stratigraphy, intrusive networks, pyroclastic flow deposits, and collapse-related features. These complementary approaches not only illuminate past eruptive and mass-wasting events but also provide insights into the current stability of volcanic flanks. The integration of seismic methods across scales therefore offers a unique opportunity for a holistic understanding of volcanic systems and for developing more robust hazard assessments.
This session welcomes contributions that apply earthquake seismology or controlled-source seismic data (from land or marine settings) to the study of modern or ancient volcanic systems. We particularly encourage studies that combine multiple approaches or datasets to advance our understanding of volcanic architecture, evolution, and associated hazards.
