T51D:
Scientific Advances from Subduction Zone Observatories IV Posters


Session ID#: 7617

Session Description:
Subduction zones contain the Earth’s richest diversity of tectonic processes, from plate-scale over millennia to grain-scale over micro-seconds. Most span continental to oceanic environments, and interact with climatological and biological processes, which multiplies the diversity and observational challenges, but also opportunities to leverage and learn.  Finally, subduction zones host many of Earth’s most extreme natural events, which coupled with increasing human populations, leads to an urgent need to understand how they work. The scientific community is exploring the potential to develop a new Subduction Zone Observatory (SZO) as a multidisciplinary facility, stretching along several circum-Pacific’s subduction zones.  A SZO would provide a comprehensive suite of multidisciplinary onshore and offshore observations to understand the entire subduction zone system.  We welcome contributions that show scientific advances resulting from coordinated instrumentation, sampling, and analog experimentation/modeling of a subduction zone, or present scientific ideas and findings relevant to future development of a SZO.
