- •
GPS and repeating earthquake data are combined to estimate coupling in NE Japan.
- •
Vp and Vs data are used to infer effective pressure, porosity, and clay content.
- •
Creeping areas overlap regions of low effective pressure and porosity.
- •
In the Tohoku rupture area both clay content and effective pressure are high.
- •
These results are discussed in the context of mechanisms driving creep.
