Subduction Zone Observation through Time and Space: Path to an SZ4D Initiative on the Science of Subduction Hazards

Session ID#: 75837

Session Description:
Subduction zone processes produce volcanic unrest, megathrust earthquakes, and shape land- and seascapes associated with plate convergence over seconds to millions of years. New technologies, including ocean-bottom and conventional seismometer networks, on- and off-shore geodetic networks, high-resolution imaging of subduction zone geomorphology, continuous multi-parameter instrumentation of volcanoes, as well as novel geochronologic, paleoseismologic, and geologic approaches, will all be critical to advancing new discoveries. At the same time, new modeling capabilities that integrate geologic and geophysical observations will be required to understand them and to develop and test hypotheses about subduction zone processes spanning human and geologic time scales. Submissions that highlight present and emerging observational capability, data acquisition, and modeling across a wide range of disciplines are welcomed. The session will also explore new research directions that promise to produce substantial advances in our holistic understanding and forecasting of subduction-related hazards in the coming decade.
