2. Science Goals and Needs
1) Understand deformation and fluid flow at geologic
(preconditioning) and event (hazard) time and
length scales
2) Fully coupled deformation, flow, reaction models
- large strain behavior, complex rheology
- strain/reaction-controlled material properties
- continental margin evolution through slope
stability
3) Easy access (uploader, user) database for data of all
scales (bathymetry through mineralogy)
4) Improving utility of large data sets in numerical
models (one permeability point vs pore-scale
imaging)

6. Impact of Easy Access Data - Tohoku
Slip facilitated by pelagic brown clay
(Moore et al., 2013)
Clay shows rapid slip weakening
(Ujiie et al., 2013)
Fault zone has lower permeability
(Tanikawa et al., 2013)

2013

7. Communication

What experimentalists and modelers have
What they want
What they need
Metadata – capture as much as possible,
allow comment by others,
adaptability (don’t know what we want
until we need it/can’t find it)
