seismic shift

A major change. (Seismology is the study of earthquakes.) The implication is that the change being described is so significant that the earth will move under your feet. Like paradigm shift, this phrase has become overused marketing hype.

In just the last century, there has been a seismic shift in the treatment of women in this country.

Ego-seismic

Thinking about the cause of an earthquake relating to yourself.

Maybe us moving, redirected the epicentre of U.S earthquakes to where we were from. I like to think of it as Ego-Seismic thinking
