What's up with China and Japan?

Looks like there is some interesting EQ's around today lately:

Japan
China
Pakistan
Indonesia

Does those EQ's falls to the same longitude? At least the same region is moving.

A 5.6 in Antarctica today as well, I dont ever remember a quake in Antarctica.
Is that unusual or what?

It's one of nine in recorded history. The first one was in 1995, though, so they probably weren't looking for them down there before then. 2012 is the only year there's been more than one quake south of -75 latitude; there have been three so far this year. So yeah. Highly unusual, but a sign of the times. (To compare, there've been over 1,400 quakes near the north pole since 1963...)
