SZ4D (Subduction Zones in Four Dimensions) is a growing, community-driven initiative aimed at transforming our understanding of subduction zone geohazards—including earthquakes, volcanic eruptions, and cascading surface processes—through interdisciplinary research and capacity building. Now entering a critical phase of project development, SZ4D is advancing proposals for major infrastructure deployments, including field arrays in the Andean subduction zone, and expanding collaborative modeling, laboratory, and data integration efforts.Community engagement remains central to SZ4D’s mission. The initiative continues to broaden participation through workshops, webinars, working groups, and an annual open call for volunteers to help shape science, infrastructure, and other activities. International partnerships, through SZNet and other avenues, are fostering global collaboration.At this Town Hall, representatives from the SZ4D leadership will present updates on recent milestones, funding strategies, and upcoming opportunities for participation. This session will offer an open forum for questions, feedback, and scientific input to guide the next stages of SZ4D development. All interested researchers and students are encouraged to attend and help drive the future of subduction zone science.
