why are the earthquakes in Japan moving south?
The first one was off the coast of sendai and a number 9. It caused a Tsunami. A huge aftershock (at around level 8) was predicted in the following 72 hours.
The one just now (about 10 minutes ago local time) was in Shizuoka and a number 6.
Are they moving along the plate line? The TV are saying this was an after shock, but not the huge one they are waiting for. Was this the big aftershock? And If so why was it so far away?

Well TV and news always blows things way out of per portion. There will be a series of aftershocks and these aftershocks are not called earthquakes. They aren't moving along the plate line. They are happening because the plate is shifting. Because the plate is shifting, different faults are also shifting or widening. After shocks can vary in distance from the initial quake, some are in the same area and other may occur along a fault line miles away. All this is possible because of the shifting or sliding earth or plate that the island is on.

An earthquake relieves stress at a point of a fault line and the aftershocks relieve secondary stress at new points along the fault. Direction does not matter.
