Honshu is very narrow in some parts from coast to coast, some under 75km, so maybe not surprising to see quakes on both sides. Obviously they are tied. I'm no seismologist, is it possible that in that close proximity they are part of the same aftershock?
Since the two are on different fault lines, then no. It wouldn't be considered an aftershock. That's not to say the main 9.1 quake didn't cause a secondary quake on another fault line though. That's entirely possible and probably what happened.

:eek: OMG! Japan has quakes and aftershocks on two coasts. The number of aftershock have been so many that it's almost one long earthquake with a 'few minutes' pauses sputtered throughout the day. May the victims R.I.P. :sad:

Oh right, so the eastern ones are on the North America/Pacific plate fault line, and the western ones on the Eurasian/North American plate fault line?

Is there an ETA for Hawaii and the US West Coast? And is there a possibility that the waves fade away? Hopefully they do.

Hawaii was hit at 8:00am this morning and the first waves arrived to the US West Coast around 11:00am or noon.
