Twardzik and Ji (2015) The Mw7.9 2014 intraplate intermediate-depth Rat Islands earthquake and its relation to regional tectonics
Summary: Finite-fault inversion and relocated after shocks suggest a deeply dipping fault plane of 87 degrees, extending from 80 to 140 km depth. This extends from the top of the slab to the 600-650 degree isotherm. This is similar to the 1993 Kushiro-oki and 2005 Tarapaca Chile earthquakes which also ruptured the region between the DWB-zones. If large intermediate depth earthquakes are not limited to the crust or slab's elastic cores, we may need to re-evaluate seismic hazards.

Summary:Some subduction zones experience earthquake supercycles. Numerical simulations show that successive megathrust earthquakes may load neighbouring parts of the fault, causing it to eventually fail in a giant earthquake that completes a supercycle.

Summary:GPS + InSAR shows central SAF Creeping Section accumulates 5-25% seismic moment which is not released by seismicity.
