It's pretty fucked up all round. The 6.4 (which is somewhat bearable by Japanese standards) was just to soften them up so the 7.3 could mince everything.
Then again, the 6.4 was pretty bad on the Japanese scale too - 6 strong or 7 which in terms of damage potential.
On the upside, the number of soon to be funerals is still relatively low for now.
