Think of it as a big clock, Chile has been having some big shakers. New Zealand - huge one just a few weeks ago. China major movement the last few weeks. Now Japan - fucking mother of earthquakes.
Now go back to my clock:
Chile about 5:00
New Zealand about 6:00
China about 9:00
Japan about 12:00
California about 3:00
I'm just saying time may be running out for those of us on the West Coast.
Of course my analogy requires that you know what a clock with hands looks like.
