Nothing over 5.5 since these:

2014/04/20 5.4 Mb at 01:54:13 EASTER ISLAND REGION -26.40 -114.99

2014/04/20 6.1 M at 00:15:58 Bougainville - Solomon Is -7.17 155.31

And that was only a 5.5 then:

Such a time lapse generally indicates tropical storms. But maybe they are storms of a different persuasion?

Once geophysics comes to terms with the fact storm tracks depend on their gyroscopic behaviour and has nothing to do with Coriolis (as Newton stated before that damn fool was even a twinkle) we will be getting track definitions every few minutes, rather than every 3 or so hours and they will have considerably closer margins too, as well!
