Well, Chile had a big quake, 8.8, Feb 2010.
 Christchurch had a 7 in Sept 2010 and a shallow more devastating one Feb 2011
Japan had a 9.0 March.
The pattern was Santiago Chile and directly across and down a little bit to Christchurch.
Next North to Sendai Japan.
If the pattern continues the next quake should be a little north of that in the Pacific NW region around Washington state.
That would make a lopsided rectangle like a rhomboid I guess.
Time wise, it seems to be speeding up.
The ring of fire seems to be adjusting itself
