Reply #6: Does anyone know exactly how many 7.0+ magnitude quakes have occurred?

I think 4, but I can't recall.

I also know there was a 7.2 magnitude "foreshock" on March 9th, but I don't know if seismologists count such foreshocks in their "totals".

Thank you for your comments MineralMan. You are right, this is definitely uncharted territory to say the least (or, "relatively uncharted" anyway). The prospect of an 8.0 somewhere near Fukushima or Tokyo is certainly worrisome though (as is the prospect of more 7.0 quakes to come!).

Things seemed to settle down for a few days, but then we had a few aftershocks one after the other a couple of days ago. And again now it's quiet (eerily quiet).

Hopefully it's calmed down now, but historically speaking that's not too comforting. Feels ominous to me.
