Making a last check of quakes before logging off for the night and noticed three 5.0+ quakes within the past 3+ hours.

They're all in the Japan trench about 200km due east of Tokyo. If memory serves at this late hour, that's south of the Tohoku rupture area.

(yep, just checked - http://www.tectonics.caltech.edu/slip_history/2011_taiheiyo-oki/)

Just noting. Hope it does not portend something more.
