Summary.

Northeast of East Cape 4.0 2.43pm
Weak solar conditions during the period are slightly typical for solstice months December and January.
A strong supermoon made no difference to a weak quake response.
Lunar position is secondary to solar activity for driving quakes...when solar conditions are weak, lunar position has no modulating effect.
Quakes may remain settled until approx. 8 January when another weak quake period may begin.
