Volcanic hazards and risk mitigation are central to the field of global geoscience. Volcanoes have far-reaching impacts on human societies and the environment. Despite their significance, volcanic systems remain among the most complex and challenging environments to study due to their inaccessibility. Our understanding of their internal structures, eruption history, and the volumes and recurrence intervals of eruptions or collapses is still limited.
In recent years, seismic imaging has become a powerful tool for investigating volcanic systems. This technique offers valuable insights into volcanic plumbing systems, their eruptive products, and associated mass-wasting deposits across various spatial and temporal scales. Advances in seismic tomography have enabled detailed imaging of volcanic plumbing systems at crustal level, revealing features such as trans-crustal mush zones and shallow, melt-rich magma reservoirs. Additionally, high-resolution reflection seismic surveys have provided detailed images of the shallow regions of volcanic systems, allowing for the study of volcanic edifice architecture, the geometry of dyke and sill intrusions, and the mapping of pyroclastic flow deposits and related mass-wasting events. Seismic imaging also offers critical information about past collapse events and the current stability of volcanic structures. By integrating seismic imaging techniques across different scales, researchers can gain a comprehensive understanding of volcanic systems, which is essential for improving risk assessments.
This session invites submissions that utilize earthquake and controlled-source seismic data (both land and marine) combined with various imaging techniques to study active or ancient volcanic systems. Contributions focused on volcanic arcs, mid-ocean ridges/rifts, and intra-plate volcanoes are all welcome.
