Major Research Gaps:

Ongoing Scientific Problems Motivated by MARGINS Research:

Work to date highlights the longevity of the scientific themes addressed in the science plans, and also sharpens the focus on particular aspects. These include:

What controls the updip limit of the seismogenic zone?

How does one define the updip limit of the seismogenic zone?

What controls the seismic energy release during subduction zone earthquakes?

What controls the locking patterns on the plate interface and subsequent energy release?

What controls propagation and slip rates and the distribution of fast, slow, tsunami, and silent earthquakes in time and space?

What is the nature of temporal changes in strain, fluid pressure, and stress during the seismic cycle?

What is the role of slow slip events in releasing the strain energy along seismogenic zones? Are these events episodic?
