1. Subduction Zone ObservatoryAn international multi-disciplinary observatory along a subduction zone plate boundary (ies?)“subduction collaboratory”2014 Fall AGU meeting, San Francisco
2. EarthScope Beyond 2018“The #1 most epic project in the universe” – Popular Science
3. Subduction Zone ObservatoryA coherent, structured, multi-disciplinary observatory along the length of the eastern Pacific
4. Subduction Zone ObservatoryMust have:Transformational & high impact scienceSocietal relevance (strong focus on hazards)International collaborationMulti-disciplinary componentsOn-shore/off-shoreNew technologiesNew high quality data Strong integration with modeling
5. Subduction Zone ObservatoryInterdisciplinary approach to solving major scientific challengesObserve the entire deformation spectrum from sec to MyrsCapture the pre-seismic, co-seismic and post-seismic deformational response to a megthrust earthquake(s)Mega thrust interface - earthquakes, slow slip events, episodic tremorTsunami generationVolcano processes & hazardsImaging the factors controlling geochemical variability in arcsLithospheric dynamics and orogeny – lithospheric destruction?Subduction of water and the Earth’s water budgetSubduction into the lower mantle and the fate of slabs
6. From O. Oncken and IPOC Group
7. Current Availability of Observations Varies Widely From SAGE proposalObservations are concentrated in some regions, sparse in others (GPS: red, seismic stations: blue)Tremendous lateral variability in the seismogenic portions of the subducting slab (brown)

10. Questions that need to be resolved soon:What are the major scientific and geographic targets? What is needed to solve the big science problems? - greatly improved observational systems - what other improvements?Should there be a longer term plan (post-2018) to start developing a more ambitious program?Who are the partners, both nationally and internationally?

13. We need your feedback and helpWe need input on future major initiativesWhat subduction zone observations does your science require that you don’t have now?Alternatively, what are the science gains from a Subduction Zone Observatory?
