Slide1
Subduction Zone Observatory
An international multi-disciplinary observatory along a subduction zone plate boundary (ies?)
“subduction collaboratory”
2014 Fall AGU meeting, San FranciscoSlide2
EarthScope Beyond 2018
“The #1 most epic project in the universe” – Popular ScienceSlide3
Subduction
Zone Observatory
A coherent, structured, multi-disciplinary observatory along the length of the eastern PacificSlide4
Subduction
Zone Observatory
Must have:
Transformational & high impact science
Societal relevance (
strong focus on hazards
)
International collaboration
Multi-disciplinary components
On-shore/off-shore
New technologies
New high quality data
Strong integration with modelingSlide5
Subduction
Zone Observatory
Interdisciplinary approach to solving major scientific challenges
Observe the entire
deformation
spectrum from sec to
Myrs
Capture the pre-seismic, co-seismic and post-seismic deformational response to a
megthrust
earthquake(s)
Mega thrust interface - earthquakes, slow slip events, episodic tremor
Tsunami generation
Volcano processes & hazards
Imaging the factors controlling geochemical variability in arcs
Lithospheric dynamics and orogeny – lithospheric destruction?
Subduction
of water and the Earth’s water budget
Subduction
into the lower mantle and the fate of slabsSlide6
From O.
Oncken
and IPOC GroupSlide7
Current Availability of Observations Varies Widely
From SAGE proposal
Observations 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)Slide8

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?Slide11Slide12

We need your feedback and help
We 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?
