So my guess is that the geomorphological response will become more pronounced over time. There are decade old studies which show an uptake in seismic activity during abrupt SLR.
A short intro into this topic
http://galaxymachine.de/2013/05/02/will-climate-change-cause-earthquakes/Because of these features i doubt migrating to the poles is a feasible option. During MP1 (Meltwater Pulse 1) there has been substantial SLR in a couple of years. Though somebody pointed out that was a different situation, however today we have unprecedented rates of emissions.
I hope that all these Arctic & Antarctic missions or some at least focus on the required degree for seismic observations.
